Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, OBD-II scanner, brake cleaner, torque wrench, micrometer, and socket set.
Safety Warnings: Ensure the vehicle is on a flat surface. Use jack stands to secure the vehicle after lifting. Always wear safety goggles and gloves.

2. Replace Uneven Brake Pads

Lift the Vehicle: Use a jack to lift the front or rear of the vehicle, depending on which brake pads are worn.
Remove the Wheel: Use a lug wrench to remove the wheel and expose the brake assembly.
Remove Brake Caliper:
- Use a socket set to unbolt the caliper from the mounting bracket.
- Carefully hang the caliper using a bungee cord to prevent stress on the brake line.
Remove Old Brake Pads: Slide the old brake pads out of the caliper bracket.
Inspect and Clean:
- Clean the caliper bracket and the mounting surface using brake cleaner.
- Check the caliper pins for lubrication and replace if necessary.
Install New Brake Pads: Slide the new brake pads into the caliper bracket, ensuring they are seated properly.
Reinstall Brake Caliper: Position the caliper over the new pads and bolt it back into place using the torque specifications from the manufacturer.
Reinstall Wheel: Place the wheel back on and hand-tighten the lug nuts before lowering the vehicle.

3. Check Brake Caliper Functionality

Inspect Caliper Movement: Ensure the caliper moves freely on its slides. If it’s sticky, consider cleaning or replacing the caliper.
Bleed Brake System: If necessary, bleed the brake lines to remove any air that could affect braking performance.
