Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during the repair.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; if less than 3mm, they should be replaced.
Remove Brake Caliper:
- Remove the bolts holding the caliper using a socket wrench.
- Hang the caliper using a bungee cord to avoid straining the brake line.
Remove Old Brake Pads:
- Slide out the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease on the backing of the new pads (if applicable).
- Insert new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors:
- Measure rotor thickness; if below minimum specifications or if scoring is visible, replace the rotors.
Remove Brake Rotor:
- Remove the caliper bracket if necessary and take off the rotor.
Install New Rotor:
- Position the new rotor onto the hub and secure it with bolts.

5. Reassemble Components

Reattach the brake caliper over the new pads or rotor.
Tighten caliper bolts to the manufacturer’s torque specifications (typically around 20-30 ft-lbs).
Reinstall the wheel and secure lug nuts to the proper torque specification.

6. Final Checks

Pump the brake pedal several times to ensure pads seat properly against the rotor.
Reconnect the battery and check the brake fluid level, adding fluid if necessary.
