Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath it.
•Allow brake components to cool down before touching, as they may be hot after use.

Symptoms

•Vibration felt through the brake pedal
•Steering wheel shaking during braking
•Increased stopping distance
•Noise (such as grinding or squeaking) when brakes are applied
•Uneven wear on brake pads or rotors

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for even wear and sufficient thickness.
3
Examine wheel bearings for play or damage by wiggling the wheel while it's off the ground.
4
Inspect suspension components (e.g., control arms, bushings) for wear or damage.
5
Verify tire condition and balance, looking for uneven wear or balancing issues.
6
Scan for any error codes related to the braking system using an OBD-II scanner.

Solution

Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, dial indicator, torque wrench, and basic hand tools.
Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are affected.
Secure the vehicle with jack stands before proceeding.

3. Inspect the Brake Rotors

Remove the wheel using a lug wrench.
Use a dial indicator to measure the runout on the brake rotor.
- If more than 0.002 inches (0.05 mm) of runout is detected, the rotor may be warped.
If warping is confirmed, proceed to replace or resurface the rotors.

4. Check Brake Pads

Inspect the brake pads for even wear.
- If pads are worn unevenly or are below the manufacturer's minimum thickness, replace them.
Ensure that the pads are properly seated in the caliper and that there is no debris preventing proper contact.

5. Examine Suspension and Wheel Bearings

Check all suspension components for wear or damage, focusing on bushings and control arms.
Inspect wheel bearings for any play by rotating the wheel and feeling for roughness or looseness.
Replace any worn or damaged parts as necessary.

6. Reassemble and Lower the Vehicle

Reattach the wheel and tighten lug nuts to the manufacturer's specified torque.
Lower the vehicle and remove the jack stands.

7. Test Drive

Conduct a test drive to confirm that the vibrations have been resolved and that braking performance is restored.
