This specific bolt is used to secure the brake caliper to the brake caliper carrier/bracket.
Technical Specifications
Thread / Dimensions: M8 x 22mm
Common Alternative Names: Caliper Guide Pin Bolt, Caliper Anchor Plate Bolt, Disc Brake Caliper Pin, Carrier Bolt, Brake Pads Bolt.
Important Service Note: According to Audi service manuals, this is a "one-time use" stretch bolt.
Because it undergoes significant stress and heat cycles, it stretches when torqued to its correct specification and cannot be safely cleaned and reused/reinstalled. It should always be replaced anytime the caliper is unbolted from the carrier (such as during a brake pad or rotor change).
Fitment
It is widely used across a broad range of modern Audi vehicles (typically from the mid-2010s through current models) including the Q3, Q5, Q7, Q8, S3, A5, S5, RS5, and e-tron series, depending on the specific brake rotor diameter package (e.g., 282mm, 300mm, 330mm rear or front setups).
