Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Wear safety glasses and gloves.

2. Remove Wheels

Loosen lug nuts with a socket set.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheels.

3. Inspect and Replace Brake Pads

Remove the caliper mounting bolts using a socket wrench.
Carefully lift the caliper and secure it (do not let it hang from the brake line).
Remove the old brake pads from the caliper bracket.
If uneven wear is noted, replace brake pads on both sides of the axle.
Install new pads, ensuring they fit snugly.

4. Check and Replace Calipers (if necessary)

If calipers are sticking, remove them by unbolting from the bracket.
Inspect for corrosion or damage; replace if necessary.
Install new calipers and torque bolts to manufacturer's specifications.

5. Inspect and Resurface/Replace Rotors

Check rotors for thickness and warping using a micrometer.
If warped, either resurface or replace the rotors.
Clean rotor surfaces with brake cleaner before installation.

6. Reassemble and Test

Reinstall the caliper over the new pads and torque bolts to specifications.
Reattach the wheel and torque lug nuts in a star pattern.
Lower the vehicle and remove wheel chocks.
