Solution

1. Preparation

Tools Required: Wheel chocks, jack, jack stands, lug wrench, socket set, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a level surface, and engage the parking brake.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brakes.

3. Inspect Brake Components

Brake Pads: Remove the caliper by unscrewing the bolts with a socket set. Check the thickness of the brake pads. Replace if they are less than 3mm thick.
Brake Rotors: Inspect the rotors for grooves and scoring. If damaged, replace them. If they are within specification, clean them with brake cleaner.

4. Replace Brake Pads or Rotors (if necessary)

If replacing pads, compress the caliper piston using a brake caliper tool. Install new pads into the caliper bracket.
If rotors are being replaced, unscrew them from the hub and install new rotors, ensuring they are properly torqued according to manufacturer specifications.

5. Reassemble and Test

Reattach the caliper and tighten the bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
