Failure 01
Bolt holes do not line up
If the bracket hole pattern is off, the bolt binds before it reaches torque. We finish critical holes on CNC and prove the pattern on the gauge.

Four ways a bracket kit fails at install.
The bracket, shim stack, sleeve, fastener, thread, and coating are checked together on one fixture before the kit reaches a carton.
VIA kit pass fixture
CHECK critical dims · every lot
Checked before pack.
A physical checking station verifies bolt-circle pins, datum seating, shim stack, sleeve length, and post-coat thread fit before the kit is released to packing.

Failure 02
Caliper sits off center
The bracket can be right and the kit can still fail if the shim pack drifts. The stack height is checked as a kit, not guessed from a nominal sheet.
Caught at · shim stack block
Failure 03
Clamp load changes
A short or long sleeve changes the clamp path. That is how a clean looking kit creates movement under brake vibration.
Caught at · sleeve length block
Failure 04
Threads gall at install
Coating can build in the thread root. Thread class is checked after coating, not before, so the installer is not fighting the bolt.

A note from the founder
I know what happens when one hole is off.
For 12+ years I was the buyer. The drawing looked right, the supplier said it was easy, and the real problem showed up at installation. One bolt would not start. One shim stack was wrong. One sleeve changed clamp load. Then the whole kit became my problem.
FitmentShip parts after CMM sampling.Gauge the full kit before it leaves.
Stack heightTreat shims and sleeves as hardware.Control the tolerance chain as one BOM.
CoatingPlate it and hope threads run.Check coating, thread fit, and torque behavior.
On your caliper bracket kit that means our network builds it and we answer for plate, machining, shims, sleeves, fasteners, coating, inspection, packing, and delivery. A brake kit is only good when it bolts on cleanly the first time.

Grade 8 or class 10.9 bolts, washers, and nuts checked for thread fit, finish, and kit count before they join bracket pack bracket.
Clean surfaceSand blasting
Machined brackets are blasted before plating so edges, recesses, and faces carry a consistent surface for coating adhesion.

Black zinc, zinc-nickel, phosphate, e-coat, or black oxide selected by spec. Thread fit is checked after coating, not before.

Inspection sweep before release
The gauge is not a final photo prop. It is where the bolt circle, shim stack, sleeve length, post-coat thread fit, and BOM count are tied to the same lot before the carton is closed.

Questions we get on the first call.
We are. The bracket, shims, sleeves, fasteners, coating, inspection, packing, and freight do not sit with six people for you to chase. We run the supplier path in India and you deal with us, one accountable name.
Yes. The bracket is cut and machined, the shims are stamped and thickness checked, spacer sleeves are turned and faced, and Grade 8 or class 10.9 fasteners are sourced or manufactured to spec. The kit is checked together before packing.
Usually it is not one dramatic failure. It is bolt true position, shim stack, sleeve length, thread class after coating, bracket flatness, or a BOM mismatch. That is why we check the kit as a stack, not as loose parts.
Yes when your program requires it. We can provide FAI, PPAP, CMM reports, thread gauge records, coating checks, salt spray results, fastener certs, and EN 10204 3.1 material certs.
Drawing or sample, bracket thickness, bolt pattern, thread callout, shim stack, sleeve length, coating spec, fastener grade, and annual volume. If you do not have everything, send what you have and we will identify the gaps.
Yes. Drawings move under NDA, and we do not disclose which partner facility makes your parts. Your bracket geometry, fitment data, and supplier path stay protected.
