Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, and safety glasses.
Raise the vehicle and secure it with jack stands.
Remove the wheels using a lug wrench.

2. Inspect Brake Components

Remove the brake caliper by loosening the caliper bolts with a socket set.
- Note: Support the caliper with a bungee cord to avoid straining the brake line.
Inspect the brake pads for uneven wear; replace if worn beyond manufacturer's specifications.
Inspect the rotors for scoring or warping. Resurface or replace if necessary.

3. Check and Repair Calipers

Test caliper movement by pressing the piston in and out.
If the caliper is sticking, it may need to be rebuilt or replaced.
Ensure the caliper slides are lubricated with brake grease to allow smooth movement.

4. Examine Brake Lines and Fluid

Inspect brake lines for any signs of leaks or damage.
Flush the brake fluid if it appears contaminated or discolored.
Replace any damaged lines and refill with manufacturer-recommended brake fluid.

5. Perform Wheel Alignment

Check wheel alignment with a professional alignment tool.
Adjust alignment as necessary to ensure wheels track straight.
Tighten all suspension components to the manufacturer's torque specifications.
