Supporting components

Inspect hats, drive-pin interfaces, brake pads, calipers, fluid and all brake hardware before installation. Do not reuse a damaged, cracked, distorted or out-of-spec hat.

Installation

Difficulty: Professional service. Ring replacement requires correct inspection, assembly practice, torque procedure, direction/orientation checks, rotor runout verification and bedding. EuroCustomsPR can inspect and rebuild the front rotor assemblies, install them and complete the brake-system review.
