Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Tools required: Jack and jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, and safety goggles.

2. Inspect and Replace Brake Rotors

a. Remove Wheel:
- Loosen lug nuts slightly while the car is on the ground.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts completely and take off the wheel.
b. Remove Brake Caliper:
- Locate the caliper mounting bolts and remove them using a socket wrench.
- Carefully slide the caliper off the rotor and secure it to avoid stress on the brake line.
c. Remove Brake Rotor:
- Take off the old rotor. If stuck, gently tap it with a rubber mallet.
d. Install New Rotor:
- Clean the new rotor with brake cleaner to remove any protective oil.
- Install the new rotor onto the hub.
e. Reinstall Caliper:
- Position the caliper back over the new rotor and tighten the caliper mounting bolts to the manufacturer’s specified torque (usually around 25-35 ft-lbs).

3. Replace Brake Pads

a. Remove Old Brake Pads:
- Slide the old pads out of the caliper bracket.
b. Install New Brake Pads:
- Insert the new pads into the caliper bracket, ensuring they are correctly positioned.

4. Check Wheel Bearings and Balance

a. Inspect Wheel Bearings:
- Spin the wheel to check for smoothness. If there’s any grinding noise or resistance, replace the wheel bearings.
b. Balance Wheels:
- If tires are unbalanced, take them to a tire shop to be balanced properly.

5. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then tighten the lug nuts to the manufacturer’s specified torque (usually around 80-100 ft-lbs).
