Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle as required.
Secure with jack stands to ensure safety while working underneath.

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Remove the wheel using a socket set.
Check the brake rotors for warping using a dial indicator gauge.
If warped (more than 0.002 inches), replace the rotors.

B. Inspect Brake Pads

Remove the caliper using a socket set.
Check the thickness of the brake pads; replace if worn below manufacturer specifications (usually 3mm or less).
Clean the caliper and bracket with brake cleaner.

C. Reassemble Brake System

If rotors were replaced, install new rotors and torque to manufacturer specifications (typically 70-90 ft-lbs).
Install new brake pads and reattach the caliper. Ensure to torque bolts to specifications (often around 25-35 ft-lbs).
Reinstall the wheel and torque lug nuts to manufacturer specifications (usually 76-80 ft-lbs).

4. Check Suspension and Alignment

Inspect suspension components for any visible damage or looseness.
If any components are worn, replace them before further diagnostics.
Perform a wheel alignment if necessary.

5. Test Drive

Lower the vehicle and perform a test drive to assess braking performance and check for vibrations.
Ensure brakes engage smoothly without pulsation or shaking.
