2
Check brake rotors for warping or uneven surfaces.
3
Examine brake calipers for proper operation and sticking.
4
Assess wheel bearings for play and wear.
5
Inspect suspension components (control arms, bushings) for damage.

Solution

1. Preparation

Gather tools needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Brake cleaner
Caliper tool (if compressing calipers)

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle 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.

3. Inspect Brake Components

Check the brake pads for thickness; replace if worn below the manufacturer's minimum specification.
Measure the brake rotor thickness and inspect for warping using a dial indicator.
If the rotor is warped beyond tolerance, replace it or have it resurfaced.

4. Replace or Repair

If necessary, replace the brake pads and rotors:
- Remove the caliper bolts and slide the caliper off.
- Replace the old pads with new ones, ensuring proper orientation.
- Install the caliper back and torque the bolts to manufacturer specifications.
- If replacing rotors, remove the rotor from the hub and install the new rotor.

5. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and then torque the lug nuts to the specified value using a torque wrench.

6. Final Checks

Reconnect the battery if it was disconnected.
Pump the brake pedal to ensure proper brake engagement before driving.
