Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the rear wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors
- Check the brake pads for thickness; if they are below 3mm, replace them.
- Inspect the rotors for scoring or warping; replace if necessary.
Replace Brake Pads (if needed)
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it with a bungee cord or wire.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads into the caliper bracket.
Replace Brake Rotors (if needed)
1. Remove the caliper bracket if replacing rotors.
2. Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
3. Install the new rotor, ensuring it is properly seated.

4. Reassemble Components

Reinstall the caliper over the new brake pads and secure it with caliper bolts.
Torque the caliper bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically around 80-100 ft-lbs).

5. Final Checks

Check the brake fluid level in the master cylinder and top off if needed.
Pump the brake pedal to ensure proper brake engagement before driving.
