Diagnostic Steps

1
Inspect brake pads and rotors for wear and damage.
2
Check rotor thickness and surface condition using a micrometer.
3
Examine brake calipers for proper function and any signs of fluid leaks.
4
Inspect suspension components including control arms and tie rods for wear.
5
Verify wheel alignment and tire balance.

Solution

1. Preparation

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

2. Lift the Vehicle

Use a floor jack to lift the front of the vehicle.
Secure with jack stands for safety.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Remove the brake caliper bolts with a socket wrench.
- Slide the caliper off the rotor and secure it aside (do not hang from the brake line).
- Remove the brake pads and inspect for wear. Replace if necessary.
Check Rotors:
- Use a micrometer to measure rotor thickness. If below specification or warped, replace rotors.
- If rotors are in good condition, you may choose to resurface them.
Reinstall Components:
- If replacing pads or rotors, install new components in reverse order, ensuring proper orientation.
- Torque caliper bolts to manufacturer specifications (usually between 20-30 ft-lbs).

4. Inspect Suspension and Alignment

Check control arms, tie rods, and bushings for wear. Replace any damaged components.
Have a professional alignment performed post-repair to ensure correct handling.

5. Reassemble and Test

Reinstall the front wheels and torque lug nuts to manufacturer specifications (typically 100-150 ft-lbs).
Lower the vehicle and remove wheel chocks.
Pump the brake pedal a few times to seat the brake pads.
