Diagnostic Steps

1
Inspect brake pads for wear; measure thickness and look for indicators of metal-to-metal contact.
2
Check brake rotors for scoring, warping, or uneven wear.
3
Examine calipers for proper function and ensure they are not seized.
4
Inspect brake lines for leaks or damage.
5

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves and goggles for protection.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Remove the wheel covering the affected brake assembly.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Remove the old brake pads by sliding them out of the caliper bracket.
- Compare the old pads with new ones to ensure identical size.
- Install new brake pads into the caliper bracket, ensuring they seat properly.

4. Inspect and Resurface/Replace Rotors

Sub-steps:
- If rotors are scored or warped, remove them by unscrewing the rotor screws (if applicable).
- If they are within specifications, clean them with brake cleaner and lightly sand to create a smooth surface.
- If damaged beyond repair, replace with new rotors of the same specifications.

5. Reassemble Braking System

Sub-steps:
- Reinstall the caliper over the new brake pads and rotor.
- Tighten caliper bolts to the manufacturer’s torque specifications (typically around 20-30 ft-lbs).
- Reattach the wheel and lower the vehicle.
