What This Part Does / Functions

•  Helps ensure consistent braking performance

Why Replace This Part?
Brake caliper mounting bolts are safety-critical fasteners. They are exposed to high braking loads, heat cycles, road debris, corrosion and repeated service removal. If a bolt is stretched, damaged, corroded, rounded or incorrectly reused, it may not clamp the caliper securely. Replacing caliper bolts with OE Genuine Porsche hardware helps ensure the brake caliper is fastened correctly using the proper factory specification.

When to Replace This Part
•  When removing or replacing a brake caliper
•  During brake caliper refurbishment or upgrade work
•  If the original bolt is corroded, seized, rounded or damaged
•  If the bolt threads are worn or contaminated
•  During front or rear brake overhaul
•  If the caliper mounting hardware is missing or incorrect

Where It Fits on the Car
This bolt fits at the brake caliper mounting point, securing the caliper to the suspension upright / hub carrier. Depending on the vehicle application, it may be used on the front calipers, rear calipers, or both.
