Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads: Remove the caliper bolts using a socket set. Slide the caliper off the rotor and inspect the brake pads for uneven wear.
Brake Rotors: Check the rotor surface for warping or scoring using a straight edge. If warped, they must be resurfaced or replaced.
Caliper: Inspect the caliper for proper operation and any signs of sticking.

4. Replace or Resurface Components

If the brake pads are worn, replace them with new pads.
If the rotors are warped, either resurface them or replace with new rotors.
Reassemble the caliper and wheel, ensuring all bolts are torqued to manufacturer specifications.

5. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts before lowering the vehicle.
Once on the ground, use a torque wrench to tighten the lug nuts to the specified torque value.
