Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, torque wrench, brake cleaner, and a dial indicator (for rotor measurement).
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Inspect and Replace Brake Pads

Remove Wheel
- Use the lug wrench to loosen and remove the lug nuts.
- Lift the vehicle with a jack and secure it with jack stands.
Inspect Brake Pads
- Remove the caliper bolts and lift the caliper away from the rotor.
- Check the thickness of the brake pads; replace if they are less than 3mm.
Install New Brake Pads
- Clean the caliper bracket with brake cleaner.
- Insert new brake pads into the caliper bracket and reattach the caliper.
- Torque caliper bolts to manufacturer specifications.

3. Inspect and Resurface/Replace Rotors

Measure Rotor Thickness
- Use a dial indicator to check rotor thickness at multiple points.
- If warped (more than 0.002" runout), resurface or replace.
Replace Rotors
- Remove the caliper and bracket.
- Remove the rotor by unscrewing the retaining screws if equipped.
- Install new rotors; torque any retaining screws to specifications.

4. Inspect Suspension Components

Check for Wear
- Visually inspect struts, control arms, and bushings for signs of damage.
- Replace any worn components as necessary.

5. Wheel Alignment and Balance

Check Alignment
- Take the vehicle to a professional alignment service to ensure proper wheel alignment.
Balance Tires
- Have tires balanced to eliminate vibrations caused by unbalanced wheels.
