Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Dial indicator (for rotor runout measurement)
Brake cleaner
Brake pad spreader tool

2. Brake Pad and Rotor Inspection

Loosen wheel lug nuts and raise the vehicle using a jack.
Remove the wheel to access the brakes.
Inspect the brake pads for thickness; replace if worn below the manufacturer’s specification.
Check the brake rotors for grooves or scoring; replace if damaged.
Measure rotor runout using a dial indicator; if greater than manufacturer specifications, replace the rotor.

3. Brake Component Replacement

If necessary, remove the caliper by unbolting it from the mounting bracket.
Remove old brake pads and install new pads using a brake pad spreader tool to compress the caliper piston if needed.
Reinstall the caliper and torque bolts to manufacturer specifications.
If rotors are being replaced, remove the old rotor and install the new rotor, ensuring it is properly seated.

4. Suspension Inspection

Inspect all suspension components for wear or damage, particularly control arms and bushings.
Replace any worn or damaged components as necessary.
Ensure all bolts are tightened to the manufacturer's specifications.

5. Wheel Alignment and Balancing

After reassembling the brakes and suspension, have the vehicle's wheel alignment checked.
Balance the wheels to ensure even tire wear and smooth operation.
