Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal.

2. Remove Wheel

Use a jack to lift the vehicle and support it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Check the thickness of the brake pads. If they are less than 3mm, they should be replaced.
- Inspect for uneven wear or damage.
Replacement:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it with a bungee cord to avoid strain on the brake line.
- Remove the old brake pads from the caliper bracket.
- Apply brake grease to the backing of the new pads to prevent noise.
- Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors

If rotors are damaged or below specification (measured with a caliper), they should be replaced.
Remove the rotor by unscrewing the retaining screws and sliding it off the hub.
Clean the hub surface before installing the new rotor.
Install the new rotor and secure it with retaining screws.

5. Reassemble and Lower Vehicle

Reinstall the caliper over the new brake pads and secure it with the caliper bolts, tightening them to the manufacturer’s specifications (usually 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal a few times to ensure proper brake engagement.
