Solution

1. Preparation

Gather tools and park the vehicle on a level surface.
Raise the rear of the vehicle using a jack and secure it with jack stands.
Remove the rear wheels using a lug wrench.

2. Inspect Brake Components

Brake Pads:
- Remove the brake caliper by unscrewing the caliper bolts (usually 14mm).
- Slide the caliper off the rotor and support it without stressing the brake line.
- Inspect the brake pads for thickness; replace if less than 3mm.
Brake Rotors:
- Check the rotor surface for grooves or uneven wear.
- If damaged, remove the rotor by unscrewing the retaining screws (if equipped) and pulling it off the hub.
- Measure the rotor thickness with a micrometer; replace if below manufacturer specifications.

3. Replace Components (if necessary)

Brake Pads:
- Install new brake pads by sliding them into the caliper bracket.
- Apply brake grease to the backing of the pads to prevent noise.
Brake Rotors:
- Install new rotors if needed, ensuring they are clean and free from grease.
- Torque the rotor retaining screws to the manufacturer’s specifications.

4. Reassemble Brake System

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the specified torque (usually around 20-25 ft-lbs).
Reinstall the rear wheels and hand-tighten the lug nuts.

5. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Pump the brake pedal several times to seat the pads against the rotors.
Check brake fluid level and top off if necessary.
