Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, C-clamp, and basic hand tools.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspection: Remove the caliper bolts and lift the caliper away from the rotor without disconnecting the brake line.
- Check for uneven wear on brake pads and measure their thickness.
- Inspect the caliper for signs of damage or sticking.
Replacement: If pads are worn unevenly, replace both pads on the affected axle.
- Use a C-clamp to compress the caliper piston back into the caliper housing.
- Remove old brake pads and install new ones, ensuring proper orientation.
- Reinstall the caliper and torque bolts to manufacturer specifications.

4. Check and Replace Rotors (if necessary)

Inspect rotors for warping or uneven wear.
If they are damaged, remove the caliper bracket and rotor.
Install new rotors if required, ensuring to lubricate contact points with brake grease.

5. Reassemble and Torque

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to manufacturer specifications.
