Solution

1. Preparation

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

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts on the rear wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Remove the Brake Caliper

Locate the caliper mounting bolts (typically 12mm or 14mm).
Use a socket wrench to remove the caliper bolts.
Carefully slide the caliper off the rotor. Use a bungee cord to hang the caliper without stressing the brake line.

4. Inspect and Replace Brake Pads

Examine the brake pads for wear. If they are below the minimum thickness (usually 3mm), replace them.
Remove the old brake pads by sliding them out of the caliper bracket.
Install new brake pads, ensuring they are oriented correctly in the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotor for any deep grooves or warping. If damaged, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install the new rotor by aligning it with the hub and securing it as necessary.

6. Reassemble Components

Replace the brake caliper over the new pads and rotor, ensuring it is positioned correctly.
Reinstall and tighten the caliper mounting bolts to the manufacturer’s specified torque (usually between 25-35 ft-lbs).
Place the wheel back on, hand-tightening the lug nuts, and lower the vehicle.

7. Final Checks

Once the vehicle is back on the ground, torque the lug nuts to the specified value (typically 80-100 ft-lbs).
Pump the brake pedal a few times to seat the pads against the rotor before driving.
