Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow the vehicle to cool before working on the brake system to prevent burns.

Symptoms

•Vehicle shakes or vibrates when brakes are applied
•Steering wheel vibrates during braking
•Uneven wear on brake pads or rotors

•Possible noise (grinding or squeaking) when braking

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a run-out gauge.
2
Check brake pads for thickness and even wear.
3
Examine suspension components (e.g., control arms, bushings) for play or damage.
4
Inspect wheel balance and alignment.
5
Scan for any error codes that might indicate related issues.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Solution

1. Preparation

Gather tools and parts: OBD-II scanner, jack, jack stands, lug wrench, run-out gauge, caliper gauge, torque wrench, brake cleaner, and new brake pads/rotors if necessary.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen 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 and Replace Brake Components

Inspect Brake Rotors:
- Use a run-out gauge to check for warping; replace if out of spec (typically >0.002 inches).
- If the rotors are below the minimum thickness specification, they must be replaced.
Inspect Brake Pads:
- Measure the thickness of the brake pads using a caliper gauge.
- Replace pads if they are worn down to the minimum thickness (usually around 3mm).
Replace Rotors and Pads (if necessary):
- Remove caliper mounting bolts and slide the caliper off the rotor.
- Secure the caliper to avoid stretching the brake line.
- Remove the rotor by unscrewing the retaining screws if present.
- Install new rotor and reattach the caliper.
- Replace brake pads and ensure they are seated correctly.

4. Reassemble and Torque

Reinstall the wheel onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground and use a torque wrench to tighten lug nuts to the manufacturer's specified torque (usually around 80-100 ft-lbs).

5. Test Brake Performance

Start the vehicle and gently test the brakes at low speed to ensure proper function and check for any vibrations.
If applicable, perform a brake bedding procedure to ensure optimal performance.
