Solution

1. Preparation

Gather tools and parts needed for repair.
Park the vehicle on a flat, level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the brakes.

2. Remove Wheel Assemblies

Use a lug wrench to loosen the lug nuts on the front wheels.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel assemblies.

3. Inspect and Replace Brake Components

A. Brake Pads and Rotors

Remove the caliper bolts using a socket wrench.
Lift the caliper off the rotor and secure it with a bungee cord (do not let it hang by the brake line).
Inspect the brake pads for wear; replace if worn down to the indicator.
Measure the rotor thickness with a micrometer; replace if below manufacturer specifications or if warped.
If necessary, install new rotors, ensuring they are properly torqued to manufacturer specifications.

B. Calipers

Examine the calipers for signs of leakage; replace if damaged.
Ensure the caliper slides are functioning smoothly; lubricate if necessary.

4. Inspect Suspension Components

Check the control arms, bushings, and any other suspension parts for wear and damage; replace as needed.
Inspect wheel bearings; if they exhibit play or are noisy, replace them.

5. Wheel Alignment

After replacing components, have a professional alignment performed to ensure proper handling and tire wear.
