Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors
- Remove the wheel using a lug wrench.
- Visually inspect the brake pads for uneven wear; replace if necessary.
- Measure rotor thickness and check for warping; resurface or replace as needed.
Check and Replace Caliper
- Inspect the caliper for signs of sticking or leaking.
- If faulty, remove the caliper by loosening the mounting bolts with a socket set and carefully disconnect the brake line (use a container to catch any brake fluid).
- Install the new caliper, ensuring it is properly aligned and tightened to the manufacturer’s torque specifications.

3. Brake Fluid Check and Replacement

Check Brake Fluid
- Remove the brake fluid reservoir cap and check the fluid level.
- If fluid is low, top off with the manufacturer-recommended brake fluid.
- If contaminated, perform a complete brake fluid flush.

4. Wheel Alignment

Perform Wheel Alignment
- Take the vehicle to a professional alignment shop or use a wheel alignment tool.
- Adjust the alignment settings to manufacturer specifications.
