Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and the keys are removed from the ignition.

2. Inspect Brake Pads and Rotors

Tools Required: Jack, jack stands, lug wrench, torque wrench
Remove the wheel using the lug wrench.
Inspect brake pads for signs of uneven wear or damage; replace if necessary.
Measure rotor thickness with a micrometer; if below manufacturer specifications, replace the rotors.
Check for warping by placing a straight edge across the rotor surface; replace if warped.

3. Replace Brake Components

Tools Required: Brake caliper tool, brake cleaner, torque wrench
If brake pads need replacing, use the brake caliper tool to compress the caliper piston.
Remove the caliper and bracket; replace old pads with new ones.
Clean the rotor surface with brake cleaner before installation.
Reinstall the caliper and bracket, ensuring proper torque settings are followed.

4. Inspect and Replace Wheel Bearings (if necessary)

Tools Required: Socket set, torque wrench, bearing puller
Remove the wheel again and inspect the wheel bearings for play.
If found damaged, remove the hub assembly and use a bearing puller to replace the wheel bearings.
Reassemble the hub and wheel, ensuring all fasteners are torqued to specifications.

5. Check Suspension Components

Tools Required: Jack, jack stands, torque wrench
Inspect control arms, struts, and bushings for wear.
Replace any worn suspension components.
Reassemble and ensure proper torque settings are followed.
