Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench, caliper tool.
Safety Warnings: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety glasses.

2. Lift Vehicle and Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a lug wrench and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Calipers:
1. Check for proper movement; ensure calipers slide freely.
2. If sticky, clean and lubricate the caliper slides with brake grease.
3. If damaged, replace the caliper.
Check Brake Pads:
1. Measure the thickness of each brake pad.
2. If pads are worn unevenly (more than 2mm difference), replace all pads on that axle.
3. Clean the caliper bracket and apply brake grease to the backing of the new pads.
Inspect and Replace Rotors:
1. Check the rotor surface for warping or grooves.
2. If damaged, replace the rotors. Ensure they are properly torqued (usually 70-100 ft-lbs depending on the model).

4. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer's specifications.

5. Test Brake System

Pump the brake pedal several times to seat the pads.
Conduct a test drive to ensure the brakes are functioning correctly and check for any unusual noises.
