Precision Brake Components from Billet

Brake system components demand tight bore tolerances, leak-free hydraulic seals, and consistent material properties. A piston bore that is off by 0.002" causes drag, uneven pad wear, or outright failure under load. We machine billet aluminum 6061-T6, 7075-T6, 4340 steel, and 17-4 PH stainless to tolerances as tight as ±0.0005". Every part is CMM inspected on critical hydraulic features.

1

Brake-Grade Materials

We machine billet aluminum 6061-T6 and 7075-T6 for lightweight calipers and brackets. 4340 steel for high-load mounts. 17-4 PH for corrosion-resistant valve blocks.

2

Hydraulic Bore Precision

We hold ±0.0005" on piston bores, seal grooves, and hydraulic port interfaces. Surface finish specs verified on CMM for leak-free brake system operation.

3

Safety-Critical Quality

Brake parts are safety critical. Every caliper body, master cylinder, and valve block gets full dimensional inspection. Material certs and heat lot traceability on every order.
