Disconnect the battery for safety while working on electrical components.

2. Inspect and Replace Brake Rotors

Remove Wheel
- Use a socket set to loosen and remove the lug nuts.
- Lift the vehicle using a jack and secure with jack stands.
Remove Brake Caliper
- Use a socket wrench to remove the caliper bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord to avoid straining the brake line.
Check Rotor Condition
- Inspect the rotor for warping or scoring.
- If warped, proceed to replace the rotor.
Replace Rotor
- Remove the old rotor and install the new rotor.
- Torque the rotor to the manufacturer’s specifications.

3. Inspect and Replace Brake Pads

Remove Old Brake Pads
- Slide the old brake pads out of the caliper bracket.
- Inspect for uneven wear or contamination.
Install New Brake Pads
- Apply a thin layer of brake grease to the back of the new pads.
- Install the new pads into the caliper bracket.
Reassemble Brake Caliper
