Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Socket set
- Torque wrench
- Brake cleaner
- Ruler or caliper gauge
Raise the vehicle using a jack and secure it with jack stands.

2. Remove Wheels

Loosen the lug nuts using a lug wrench before raising the vehicle.
Remove the lug nuts and take off the wheels to access the brake components.

3. Inspect Brake Components

Brake Pads:
- Measure the thickness of each brake pad using a ruler or caliper gauge.
- Replace any pads that are significantly thinner than the others.
Brake Rotors:
- Check for warping by measuring rotor thickness at multiple points.
- Resurface or replace rotors that show significant wear or warping.
Brake Calipers:
- Inspect calipers for signs of sticking or uneven movement.
- Clean and lubricate the caliper slides; replace calipers if they are faulty.

4. Check Brake Fluid and System

Inspect the brake fluid level and condition, replacing it if contaminated.
Bleed the brake lines to remove any air that may cause uneven braking.

5. Reassemble

Replace wheels and secure with lug nuts, torquing to manufacturer specifications.
Lower the vehicle and perform a final check of all components.
