Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, wire brush.
Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheels to access the brake components.

2. Inspect and Clean Components

Sub-steps:
- Remove the brake caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it using a bungee cord or similar device to avoid stressing the brake line.
- Take note of the brake pad condition and compare each pad for uneven wear.
- Clean the caliper and rotor surface using brake cleaner and a wire brush to remove dust and debris.

3. Replace or Recondition Brake Pads

Sub-steps:
- If pads are worn unevenly, replace them with new ones, ensuring they are of the same type and quality as the original.
- Apply brake grease to the backing of the new pads to reduce noise and enhance performance.
- Reinstall the caliper and torque the caliper bolts to the manufacturer's specifications (usually around 20-25 ft-lbs for most vehicles).

4. Examine and Replace Other Components

Sub-steps:
- Inspect the brake rotors; if they show signs of uneven wear or warping, replace them.
- Check the brake calipers for proper operation; if they are sticking, consider rebuilding or replacing them.
- Inspect brake hardware (shims, clips) and replace if damaged.

5. Reassemble and Test

Sub-steps:
- Reinstall the wheels and lower the vehicle from the jack stands.
- Pump the brake pedal to ensure the pads properly seat against the rotors.
- Test drive the vehicle to ensure brakes operate smoothly and evenly.
