Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface, engage the parking brake, and ensure the vehicle is in "Park".
Wear safety goggles and gloves.

2. Inspect and Replace Brake Pads

Remove Wheel
- Use a socket set to remove the lug nuts and take off the wheel.
Inspect Brake Pads
- Check the thickness of the brake pads. If they are worn down to less than 3mm, replace them.
Remove Brake Caliper
- Use a torque wrench to remove the caliper bolts. Safely hang the caliper using a bungee cord or wire to avoid stressing the brake line.
Replace Brake Pads
- Remove old brake pads and install new pads (ensure they are oriented correctly).
- Apply anti-squeal lubricant to the back of the pads.

3. Inspect and Replace Rotors

Check Rotor Condition
- Visually inspect the rotors for warping or scoring. Use a dial indicator to measure any runout.
- If the rotors are warped (>0.005 inches), they should be replaced.
Remove Rotors
- If necessary, use a hammer to gently tap the rotors free from the hub.
Install New Rotors
- Install new rotors, ensuring they are seated properly on the hub.
- Torque the rotor retaining screws to manufacturer specifications.

4. Reassemble

Reattach Brake Caliper
- Reinstall the caliper over the new pads and rotor. Torque the caliper bolts to manufacturer specifications.
Reinstall Wheel
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and use a torque wrench to tighten the lug nuts to the specified torque.

5. Test Brake System

Before driving, pump the brake pedal to ensure proper pad seating and brake function.
