Installation Notes and Tips

When installing the BBB Industries 99-02125A caliper on an Audi S4, ensure the brake system is properly bled using the included bleeder screw to remove air from the hydraulic lines. Verify that the caliper slides are clean and lubricated to prevent binding. Since brake pads and anti-squeal shims are not included, inspect existing pads and hardware for wear and replace as necessary. Use the provided bracket for secure mounting, but note that bracket mounting bolts are not included and must be sourced separately.
