Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Lift the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper mounting bolts using a socket set.
Slide the caliper off the rotor and secure it with a bungee cord or rope to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper bracket for any debris or wear; clean it if necessary.
Install new brake pads, ensuring they are positioned correctly in the bracket.

4. Check and Replace Caliper (if necessary)

If caliper movement is restricted, check for sticking pistons.
Remove the caliper from the bracket and inspect the piston for any damage or corrosion.
Replace the caliper with a new one if it is found to be defective.
Bleed the brake system to remove any air trapped in the lines.

5. Reinstall Components

Reattach the caliper over the new brake pads and tighten the mounting bolts to the manufacturer’s torque specifications.
Reinstall the wheel and lug nuts, tightening them in a star pattern to ensure even pressure.

6. Final Inspection

Lower the vehicle and pump the brake pedal several times to seat the new pads.
Check brake fluid levels and top off if necessary.
