⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the vehicle to cool down before working on brakes.
•Ensure the vehicle is securely lifted and supported before working under it.

Symptoms

•Steering wheel shakes when braking
•Pulsation felt in the brake pedal
•Vibration increases with speed
•Uneven brake pad wear
•Noise coming from the brakes (squealing or grinding)

Diagnostic Steps

1
Inspect brake pads for uneven wear and thickness.
2
Check rotors for warpage or thickness variation using a micrometer.
3
Examine brake calipers for proper operation and any sticking issues.
4
Inspect wheel bearings for play or damage.
5
Verify tire condition and balance, including checking for uneven wear.

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

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

Diagnostic Steps

1
Inspect brake pads for uneven wear and thickness.
2
Check rotors for warpage or thickness variation using a micrometer.
3
Examine brake calipers for proper operation and any sticking issues.
4
Inspect wheel bearings for play or damage.
5

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on the electrical components.

2. Inspect and Replace Brake Pads

Remove the wheel:
- Use a lug wrench to loosen lug nuts.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the lug nuts and take off the wheel.
Remove brake caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it using a bungee cord or rope.
Inspect brake pads:
- Check the thickness of the pads; replace if below manufacturer specifications.
- Look for uneven wear patterns.
Install new brake pads:
- If replacing, slide the new pads into place on the caliper bracket.
- Reattach the caliper over the new pads and tighten the mounting bolts to manufacturer torque specifications.

3. Inspect and Resurface/Replace Rotors

Check rotor condition:
- Measure rotor thickness and check for warpage using a micrometer.
- If warping is found, either resurface or replace the rotors.
Resurface rotors (if applicable):
- Remove rotors from the hub by unscrewing the retaining screws.
- Take to a machine shop for resurfacing as per manufacturer guidelines.
Install rotors:
- If replacing, install new rotors onto the hub.
- Secure with retaining screws and ensure they are torqued correctly.

4. Reassemble and Test

Reattach the wheel and tighten lug nuts in a crisscross pattern.
Lower the vehicle and reconnect the battery.
Test drive the vehicle to ensure vibrations have been resolved.
