Inspect the brake rotors for warping or damage using a dial indicator.
2
Check brake pads for uneven wear or glazing.
3
Examine wheel alignment using an alignment machine.
4
Inspect suspension components for wear or damage, including control arms and bushings.

Solution

1. Preparation

Gather all necessary tools and parts before starting.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Remove Wheel

Use a lug wrench to loosen the wheel lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel by fully loosening and taking off the lug nuts.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Use a dial indicator to check for warping; replace if out of specification (typically more than 0.002 inches).
Replace Brake Pads:
- Remove caliper bolts using a socket set.
- Carefully slide the caliper off the rotor without stretching the brake line.
- Remove the old brake pads and install new ones, ensuring proper positioning.
- Reattach the caliper and torque bolts to the manufacturer’s specifications (usually around 20-30 ft-lbs).

4. Wheel Alignment (if necessary)

Take the vehicle to a professional alignment shop or use an alignment tool.
Adjust camber, caster, and toe to manufacturer specifications.

5. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the manufacturer’s torque specification (typically around 80-100 ft-lbs).
Remove jack stands and lower the vehicle completely.
