Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear.
2
Check brake pads for wear and proper installation.
3
Examine suspension components, including control arms and bushings, for damage or wear.
4
Verify wheel alignment and balance.
5

Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels.

2. Lift Vehicle

Use a hydraulic jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Inspection:
- Check for any signs of warping or uneven wear on the rotors.
- Measure rotor thickness using a micrometer; if below specifications, replace.
Replacement:
- Remove the caliper bolts and carefully take off the caliper. Support it with a bungee cord to avoid straining the brake line.
- Remove the old rotor and clean the hub surface with brake cleaner.
- Install the new rotor, ensuring it is seated properly.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically 25-35 ft-lbs).

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper bracket for debris and clean it if necessary.
Install new brake pads, ensuring they are properly aligned and seated.
Apply brake grease to the backing of the pads (not on the friction surface).

5. Check Suspension Components

Inspect control arms, tie rods, and bushings for wear or damage.
Replace any worn components as needed, ensuring all bolts are torqued to specifications.

6. Wheel Alignment and Balance

After reassembling, take the vehicle to a professional for alignment and balance if any suspension parts were replaced.
