Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Lift the vehicle using a jack and secure with jack stands.

2. Remove Wheel

Use a lug wrench to loosen the wheel lug nuts.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Examine the brake caliper for signs of sticking or corrosion.
Check the brake pads for uneven wear; note which pads are worn more.
Inspect the brake rotor for warping or excessive wear.

4. Replace Brake Pads (if necessary)

If pads are unevenly worn:
1. Use a socket set to remove the caliper bolts.
2. Carefully slide the caliper off the rotor.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads into the caliper bracket.
5. Compress the caliper piston using a brake caliper tool to fit over the new pads.

5. Reassemble Components

Reattach the brake caliper over the new brake pads.
Tighten the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and tighten the lug nuts in a star pattern to the specified torque.
Pump the brake pedal to ensure proper pad seating and caliper operation.
