Solution

1. Preparation

Gather tools and parts.
Ensure vehicle is parked on a level surface with the parking brake engaged.
Wear safety gloves and glasses.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle as necessary.
Secure with jack stands.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspection:
- Check the thickness of the brake pads; replace if less than 3mm.
- Look for uneven wear or glazing on the pads.
Replacement:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring proper orientation and alignment.
- Reattach the caliper and torque bolts to manufacturer specifications (usually around 25-35 ft-lbs).

5. Inspect and Resurface/Replace Rotors

If rotors are warped or scored:
- Remove the rotor from the hub.
- Option to resurface the rotor or replace it with a new one.
- If resurfacing, verify the rotor thickness remains within specification.
- Reinstall rotor and torque mounting bolts to manufacturer specifications (typically 80-100 ft-lbs).

6. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and then torque the lug nuts to manufacturer specifications (usually 80-100 ft-lbs).

Tools Required:

Jack and jack stands
