2
Check brake rotor thickness using a micrometer to ensure they are within specifications.
3
Examine brake pads for uneven wear or contamination.
4
Inspect suspension components for wear or damage, including control arms and ball joints.

Solution

1. Preparation

Gather necessary tools and parts.
Tools Required: Jack and jack stands, lug wrench, micrometer, brake cleaner, torque wrench, socket set, impact wrench.
Parts Required: New brake rotors, new brake pads, brake hardware kit (if necessary).
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using the jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Check for warping or grooves on the surface.
- If warped, replace with new rotors.
Inspect Brake Pads:
- Check the thickness of the pads; replace if below minimum thickness.
Remove Old Components:
- Use a socket set to remove the caliper bolts and lift the caliper off the rotor.
- Remove the old brake pads and rotors.
Install New Rotors and Pads:
- Clean the new rotors with brake cleaner to remove any protective coating.
- Install the new rotor onto the hub.
- Place the new brake pads into the caliper bracket.
Reattach Caliper:
- Position the caliper over the new pads and rotor.
- Tighten the caliper bolts to manufacturer specifications using a torque wrench.

4. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts before lowering the vehicle.
Once on the ground, torque the lug nuts to the specified setting (typically 80-100 ft-lbs).

5. Test Brakes

Lower the vehicle and pump the brake pedal to seat the pads.
Perform a test drive to ensure braking performance and check for vibrations.
