Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical short circuits during repairs.

2. Remove the Wheel

Using a jack, lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper by unscrewing the mounting bolts with a socket set.
- Lift the caliper off the rotor and support it using a bungee cord (do not let it hang by the brake line).
- Check the brake pads for wear; if they are less than 1/8 inch thick, replace them.
Replace Brake Pads:
- If replacing, slide new brake pads into the caliper bracket.
- Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications (usually around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for scoring, warping, or thickness below the minimum specification.
Replace Rotors:
- If needed, unbolt the rotor from the hub.
- Clean the hub surface before installing the new rotor.
- Install the new rotor and secure it with the appropriate bolts, torquing them to specification.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern.
Reconnect the battery and perform a test drive to ensure repairs are effective.
