2
Check for rotor warpage using a dial indicator or runout gauge.
3
Examine brake calipers for proper operation and any sticking or binding issues.
4
Inspect suspension components (tie rods, ball joints, control arms) for wear or damage.
5

Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (if necessary) to prevent electrical issues.

2. Remove Wheels

Tools Required: Jack, jack stands, tire iron
Loosen the lug nuts slightly before raising the vehicle.
Use the jack to lift the vehicle and place jack stands for safety.
Remove the lug nuts completely and take off the wheels.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Check for uneven wear and replace pads if they are below 3mm thickness.
Inspect and Resurface or Replace Rotors:
- Check the rotors for warpage using a dial indicator. If warpage exceeds manufacturer specifications, either resurface or replace the rotors.
Check Calipers:
- Ensure calipers are not sticking; clean or replace if necessary.

4. Inspect Suspension Components

Check for any play in the tie rods, ball joints, and control arms. Replace any worn components.

5. Reassemble

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (generally 80-100 ft-lbs, but verify with the vehicle manual).
