Solution

1. Preparation

Gather necessary tools and parts.
Secure the vehicle on a flat surface and engage the parking brake.
Wear appropriate safety gear (gloves, goggles).

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Remove Brake Components

Remove Brake Caliper:
- Use a socket set to unbolt the caliper from the bracket.
- Carefully hang the caliper using a bungee cord to avoid straining the brake line.
Remove Brake Pads:
- Slide the brake pads out of the caliper bracket.

4. Inspect and Replace

Inspect Brake Pads:
- Check for uneven wear; replace any worn pads with new ones.
Inspect Brake Rotors:
- Measure rotor thickness; replace if below manufacturer specifications.
- Check for signs of warping or scoring; replace if necessary.
Inspect Calipers:
- Check for proper operation; replace if calipers are sticking or damaged.

5. Reassemble

Install New Brake Pads:
- Apply anti-squeal lubrication to the back of the pads and install new pads into the caliper bracket.
Reattach Brake Caliper:
- Position the caliper over the new pads and secure with bolts.
- Torque bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).

6. Final Checks

Reinstall the wheel and lower the vehicle.
Pump the brake pedal to ensure proper pad seating.
