Brake Caliper Press Tool

Compare capabilities and delivery evidence. Source discovery, qualification, deployment and accepted outcomes are separate; an open contract names work still to verify.

Nishi even-pressure dual-piston caliper press with force indication (designed from the first bit up) vs single-plate spreaders and ratcheting dual-plate presses and rear wind-back kits and the EPB scan lane -- Aug-2026 field

Overview

The purpose, declared position and evidence coverage of this domain. Source presence and completed acceptance are different measures.

Where we are. MEASURED 2026-08-19: no Nishi hardware. In tree and measured: the product decomposer, the sovereign slicer, the landed-cost corridor engine and the sourcing-mix pricer. The field is mirrored: commodity single-plate spreaders, ratcheting dual-plate presses with no force feedback, rear wind-back kits, and the EPB scan lane that owns service mode on electronic parking brakes.

Where we need to go. OPERATOR ASK (2026-08-19): a better double brake caliper expander. The design thesis: even pressure BY GEOMETRY plus clamp-force indication with overload refusal plus a rear wind-back head plus an EPB workflow card -- the four capabilities the incumbent classes each hold one of and none holds together.

The unit. 1 u = one measured session-leg (organ plus gate plus live flip), the standing calibration.

Cost to a proven design pack: 3 u. BT1 force model against a load-cell fixture, BT2 even-press geometry with displacement-delta gate, BT3 fluid and EPB data cards.

Cost to a priced BOM and manufacturing verdict: 2 u more. BT4 composes lc_calc and sp_mix over the steel and hardware list. 5 u cumulative.

Cost to a bench-proven first article: 3 u more plus hardware. BT5 printed-fixture lane then machined prototype, BT6 bench gate on real dual-piston calipers. 8 u cumulative.

Research bar. The dual-plate ratcheting class, best incumbent is measured on the 2026 review field on multi-piston caliper presses. Theirs: dual push boards compress paired pistons evenly enough to win reviews [presspicks]. Ours: our BT2 gate must beat it MEASURABLY: piston displacement delta under a declared threshold on a dual-piston fixture, plus the force indication the class lacks [pistonpicks].

Business case

Axis	Position	Figures	Decision
Investment	Design and gate legs are organ work; hardware exposure is one load-cell, printed fixtures and one machined prototype batch	estimated 8 u to a bench-proven article; incumbent tools for teardown cost tens of dollars each [pistonpicks]	fund the organ leg now; buy the three incumbent classes for teardown -- the cheapest competitive research in the estate
Market	The caliper-tool shelf is a crowded commodity lane at the bottom [gjthread] and undifferentiated in the middle [presspicks]; nobody sells force-indicated even-press	the wedge is the measured tool: even-press proof plus force gauge plus EPB card, priced above the ratchet class and below shop hydraulics	sell the measurement, not the steel -- the gate results ship WITH the tool as its spec sheet
Opportunity cost	Smallest of the three product lanes; BT1 (thread mechanics) and BT4 (BOM costing) are reusable across the physical program	low blast radius, fast proof of the physical-lane workflow	use this lane as the pathfinder article for the physical-products program
Go to market	Mechanics buy on forum reputation and review-field placement [gjthread] [presspicks]	review-field placement is earned by the measured spec sheet no rival publishes	seed the measured evenness and force data publicly; the honest spec IS the marketing
Buy vs build	Every incumbent class is a cheap BUY today; the four-capability combination does not exist to buy	BUILD only the combined article; BUY all three incumbent classes as teardown references [pistonpicks]	build the wedge, buy the references

Evidence profile — what the gaps on this board actually are

Measured by nx_swcompare_evidence, read back by nx_evprofile_lib. Every figure is a count with its denominator — there is deliberately no score, no grade and no percentage anywhere in this band, because a stored scalar is a field a seat can edit and a counted partition is not.

proven able to fail counts the gates that have a RECORDED RED — nx_gate_bite mutated the gate subject, rebuilt it, watched the gate go red, and that record is inside the shared TTL. never bitten is its complement over the same denominator: those gates ran and were green, and nothing has ever shown them able to detect anything, so their green is a statement about this run and not about the gate. green at 0/0 is a separate and much weaker observation — the gate printed GREEN on a zero denominator, so its own tooth counter says it examined nothing. A gate can be green, non-zero, and still never bitten; that is the common case and it is now visible instead of implied.

partition: grounded + unsupported = 7 vs present 7 · named + unnamed + withheld = 7 vs open 7 · both reconcile

liar-kill conj=GPqN · first failing conjunct: quorum

graded document: BUILDROOT tree, 6087 bytes · gates map: NONE · stamped 36d 23h ago · STALE against the shared TTL of 604800s — this is evidence about a build nobody can vouch for now · source ../knowledge/status/evstamp_braketool.verdict

Gap class	What it is, and the work it names
CLAIM-ONLY	No declared gate ran for this board, so every capability mark here rests on a symbol existing in source and on nothing executing. The remedy is to WRITE a `.gates` map naming gates that already run — authoring, not research.
STALE	This profile is older than the shared TTL, or its clock ran backwards. It is reported as unusable rather than as fresh, because being wrong in the direction of refusing is the safe direction.

This band reports the referee counts. The per-axis worklist rows — which axis is unsupported, which watch is ready to flip, which gap is unnamed — are printed by nx_swcompare_evidence braketool itself and are not carried on the stamp, so this page names the classes and the producer names the rows. That split is stated rather than hidden: a count without a worklist is not actionable, and this band is honest about which half of that it is.

Production map

Follow the dependencies, declared acceptance criteria and recorded priorities. Inspect source binding before treating a rank as executable work.

Ranking source binding: PLAN_MATRIX_BOUND_ONLY. Recorded priorities require current acceptance evidence and resource checks before execution.

Ranking matches the captured plan and matrix only. Latest execution outcome, research freshness, accepted delivery and investment return are unverified.

Recorded priority estimates

Order from nx_compare_rank (nx_dr_ocm: (deficit + cost-of-delay + option + enables) x sponsor x self-sufficiency x momentum / cost). FINISH rows are rungs whose symbol is present but whose organ is short of full adoption: listed before new work by this heuristic. Priority is not measured delivery cost or execution readiness.

Ladder verdict. NOT DECLARED. This board names no dated best-in-class or frontier target and no rung roles (sotatarget and rungrole rows on its plan); the ranker labels it NO-LADDER until it does, and until then its rungs climb toward a target nobody has written down. Bars read NO-BAR against the current month 2026-10.

Rung dossiers — every record that bears on a rung, in one place

Joined by symbol, never typed. Each dossier is assembled on every publish from the rows this board already carries: the plan's rung row, the matrix row that carries its contract symbol (its status re-measured by the one symbol ruler), the gate the organ declares and the verdict the evidence referee recorded on its last run, the reference marks in the rung text, the design rows that name the rung and the work log filed against it. The capability matrix links each cell to its dossier and each dossier links back to its cell and forward to the rungs it stands on; a dependency naming no rung on this plan is written as UNRESOLVED rather than linked. Absences are named: NO-MATRIX-ROW, NO-GATE-DECLARED, UNRECORDED.

Gate verdicts: UNSTAMPED — no per-gate verdict artifact is published for this domain yet (nx_swcompare_evidence braketool writes it beside its stamp); every gate below reads UNRECORDED until it runs.

Gate declarations: knowledge/organ_gate.conf read from this working directory (1 rows) and from the estate root (196 rows); rows in both counted once: 0; declarations read: 197. Every declaration in either copy counts, so a stub beside the publisher can never hide the root.

Capability comparisons

Compare the field, search individual capabilities and open their source and adoption evidence. Documented presence does not establish comparative quality.

Position map — centrality and distinctiveness

The four-quadrant map the field uses for brand strategy (Dawar and Bagga, HBR June 2015), re-derived from this matrix on every publish. Centrality is the share of the category's feature mass a player covers, each feature weighted by how many hold it; distinctiveness is the average lead over each rival on the rows the player holds; breadth is the depth-weighted share of the whole matrix (the bubble); depth is how deeply the rows held are held; momentum is the day-over-day move off the spine (green rising, red falling, grey until day two); the dashed path runs first day → previous day → today. Dividers are the category means. Axes are fitted to the field of play, so read the tick numerals, not the frame. Rival marks are documented presence, so a rival's position reads the record, never its quality. The picture grades its own readability below; the table beside it is the same data for a screen reader or a second method.

Rows. 14 feature rows mapped of 14 matrix rows; 0 substrate rows (kernels, bounds and instruments the plan's rungrole marks substrate) are the estate's scaffolding, not category features, and stay off the map

Views. 2D cut: centrality, distinctiveness · 3D cube: centrality, distinctiveness, breadth · axes registered: centrality, distinctiveness, breadth, depth, momentum · a board picks its own in knowledge/compare/braketool.cdmap (cut|x|y, cube|x|y|z); absent = the HBR defaults

How to read this evidence. A Nishi source mark records whether the named symbol is declared in the selected source file. It does not establish working behavior or accepted delivery. A watching tag names an expected source entry; discovering it updates source coverage only. A dark tag means the file exists but the named symbol was not found: inspect the source and contract before assuming the capability is missing or renaming code. Peer codes are authored assessments; unassessed means no comparison is established, not absence. Qualification, deployment identity, runtime observations and acceptance must carry their own evidence. Adoption records the catalog's observed path through source, build, promotion, registration and invocation; libraries use importer evidence and gates use declared execution surfaces. A full catalog path does not establish quality, freshness or a successful user outcome. Partial and unknown states retain their stated next action. Census stamps: importers asof 1790637268, gate census asof 1790104131 (unix seconds; -1 = census absent).

Rival-claim provenance. Every Yes, Best or Part mark in a rival column is a claim about someone else's product. A cited row carries a reference mark that resolves to a pinned mirror (the refs gate measures that); an uncited row is an observation read and is badged in its evidence until a reference lands. The badge is the receipt, never the proof: a mark proves a mirror exists, not that the mirror supports the code. The rows are counted below.

Rival claims, counted

rows with rival marks	5	rows carrying a Yes, Best or Part in a rival column

Risk register

Risk	Likelihood x impact	Mitigation
Brake work is a safety domain -- a tool that damages a seal or an EPB actuator creates a braking failure	possible x severe	BT3 encodes the scan-lane requirement as a refusal card [foxwellepb]; BT6 witnesses the force-ceiling refusal on real calipers; no article ships on partial coverage
A watch contract flips on symbol existence, so a stub reads green	possible x high	the flip is the receipt, the rung gate is the proof
The commodity floor undercuts the price	probable x medium	the biz position is the measured spec, not price; M1 gates the manufacturing decision on real BOM numbers

On these two registers. Rows are declared in the domain's plan file and carry the debt id, which is the join key back to the sovereign debt plane — that plane, not this page, is the authority on state. Reconciling them automatically (the regen reading the plane and refreshing these rows) is a named, owed rung; until it lands, treat an id here as a pointer to look up, not a status to trust.

Honest verdict. The Aug-2026 hand-tool field, honestly: single-plate spreaders and plain C-clamps own the single-piston case at commodity prices and working-mechanic forum practice happily uses an old pad and a clamp [gjthread]. Ratcheting dual-plate presses -- the FIVE BANANAS pick of the 2026 review field [presspicks] and the TUTOOLS, BARTOO and OMT class beside it [pistonpicks] -- push paired pistons with matched boards, but none publishes force feedback or an evenness proof, and reviewers note the ratchet mechanisms need pressure on both plates before they act. Wind-back kits own the rear rotate-while-press case the dual-plate class cannot touch. And the electronic-parking-brake era moved part of the job into the scan lane entirely: an EPB caliper must be motor-retracted into service mode before any press, or the actuator and mechanism are damaged [foxwellepb] [epbreset]. The better double expander is therefore not a stronger screw. It is even pressure BY GEOMETRY, clamp-force indication with an overload refusal (the exceed nobody ships), a rear wind-back head so one tool spans the axle set, and an EPB workflow card bound to the tool -- each proven by its own gate before steel is cut, with the BOM priced through the estate landed-cost and sourcing engines.

Person · product · place — not yet measured for this domain

Every compare carries this layer. Declare knowledge/compare/braketool.ppp (rows surface|nishi or c1..c4|label|url|connect naming OUR live surface and each rival's front door), run nx_ppp_probe domain braketool, and this section fills itself on the next beat: the same ruler on both sides — privacy and CX (third-party hosts, tracker classes, cookies, security headers), design and longevity (design hygiene, computed WCAG contrast, render-blocking resources, unsized media, script weight, theme and motion queries), findability (landmarks, skip link, on-site search, breadcrumb, headings, internal links).

The field — discovered, not chosen

Rows written by nx_field_discover from braketool.seeds: the industry's own lists (Wikipedia wikitext, GitHub topics, awesome lists) read mechanically, every candidate counted across seeds. The matrix columns above are a SEAT'S pick; this band is the population they were picked from, and the stats line measures one against the other. A rival here is a lead, never a verdict — it earns a column when its capabilities are read and pinned.

Discovery receipt. One row per counter the run wrote, in the receipt's own order; the rival rows follow in their own table.

Exclusive and shared capabilities

One capability is graded on one board; every other board references it. The fleet duplicate census (nx_rivalcensus dupes, on the fleetdupes clock row) reads every board's matrix and names each capability graded as a row on two or more boards, with a home derived from evidence: rung when exactly one board's plan contracts the symbol (that board is starred), gates when no plan contracts it and exactly one board's executed gate map runs the organ's gate (that board is plussed), ambiguous when several boards carry the deciding evidence (a decision for their seats), and none when no evidence decides it, with the reason beside it: unmapped (no board of the duplicate declares a gates map; declare the maps) or unproven (a map exists and runs none of the organ's gates; gate the organ on its proving board, or declare it a shared library by policy). A home elsewhere means this board should carry an @xrow reference to the home board's row rather than a graded row of its own; a home here means the other boards should. The table is this board's slice of one estate-wide census: the shape is shared, the rows are the board's.

This board grades 14 capabilities: 8 exclusive to it and 6 shared with other boards. Shared rows on this page: 6 = home here 0 + home elsewhere 1 + ambiguous 0 + undecided 5 + refused 0 (partition 6); undecided = unmapped 2 + unproven 3 + unevidenced 0; homonyms 0; since the previous census: new 0, resolved 0. Census FRESH age_s=6686.

Gaps from the record — what the estate does that no board carries

The record census (nx_goalmap record) reads the invoked-tool population and every plan queue row and files each organ or directive that NO matrix, plan or gates row names. A row here is a callout the boards missed: adjudicate it onto a board or declare it infrastructure. Census state STALE (age 1395791 s), sources read 4 of 7 declared — a BLIND census is a FLOOR: unread sources can only add rows.
