Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Remove the wheel from the hub.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Check the thickness of each brake pad. If any are below the manufacturer's minimum specification, replace them.
- Look for uneven wear patterns indicating potential issues with calipers or suspension.
Inspect Brake Rotors:
- Measure rotor thickness using a micrometer. Replace if below specifications.
- Check for warpage by spinning the rotor and observing for wobble.
Caliper Inspection:
- Ensure the caliper slides smoothly. If sticking, remove and clean caliper guide pins.
- Replace caliper if damaged or malfunctioning.
Brake Pad Replacement:
- If new pads are required, compress the caliper piston using a brake caliper tool.
- Install new brake pads ensuring they are oriented correctly.
- Reinstall the caliper and torque bolts to manufacturer specifications.

4. Reassemble and Test

Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to the specified torque.
Lower the vehicle and pump the brakes to ensure proper pad seating.
Test drive the vehicle to confirm the issue has been resolved.
