Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Safety Warning: Ensure the vehicle is on a flat surface and engage the parking brake.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheels using a lug wrench.

3. Remove Brake Components

Remove Brake Caliper:
- Use the socket set to remove caliper bolts.
- Carefully slide the caliper off the rotor (do not let it hang by the brake line).
Remove Brake Pads:
- Remove the retaining clips or pins holding the brake pads in place.
- Slide out the brake pads from the caliper bracket.
Remove Brake Rotor (if necessary):
- If the rotor is to be replaced, remove any retaining screws and slide the rotor off the hub.

4. Inspect and Replace Components

Inspect Brake Pads and Rotors:
- Check pads for uneven wear and replace if thickness is below manufacturer specifications.
- Inspect rotors for grooves or warping; replace if necessary.
Install New Brake Pads:
- Apply brake lubricant to the backing of the new pads.
- Install the new pads into the caliper bracket.
Install New Rotor (if applicable):
- Clean the new rotor with brake cleaner before installation.
- Slide the rotor onto the hub and secure with screws if applicable.

5. Reassemble Brake System

Reinstall the caliper over the new pads and rotor.
Torque caliper bolts to manufacturer specifications.
Reinstall the wheel and torque lug nuts in a star pattern.

6. Final Checks

Lower the vehicle and pump the brake pedal to seat the pads.
Check brake fluid level and top off if necessary.
