Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and securely supported with jack stands.

2. Remove Wheel

Use a lug wrench to remove the lug nuts from the wheel.
Lift the vehicle with a jack, then remove the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Check the brake pad thickness and note the wear pattern.
- Inspect the calipers for sticking or improper operation.
Replacement:
- If pads are unevenly worn, remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it without straining the brake line.
- Remove the old brake pads from the caliper bracket.
- Apply brake grease to the back of the new pads and install them in the bracket.
- Compress the caliper piston using a C-clamp to fit over the new pads.
- Reattach the caliper and tighten bolts to the manufacturer’s torque specifications (usually around 18-25 ft-lbs).

4. Inspect and Replace Brake Rotor (if necessary)

If rotors are warped or damaged, remove them by taking off the caliper bracket.
Install new rotors, ensuring they are clean and properly seated.
Reassemble the caliper over the new rotor and pads.

5. Reassemble Wheel and Final Checks

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use the torque wrench to tighten lug nuts to the specified torque (usually around 75-85 ft-lbs).
Repeat the process for the other side if necessary.
