Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands to support the vehicle while working underneath.
•Allow brakes to cool if they have been recently used to avoid burns.

Symptoms

•Steering wheel shakes during braking
•Vibration felt through the brake pedal
•Uneven brake pad wear
•Pulsating or grinding noise when braking
•Vehicle pulls to one side during braking

Diagnostic Steps

1
Inspect brake rotors for warping or damage using a run-out gauge.
2
Check brake pads for uneven wear and proper thickness.
3
Examine suspension components (control arms, bushings, tie rods) for wear or damage.
4
Verify tire balance and alignment by checking tire pressure and inspecting for uneven wear.
5
Use an OBD-II scanner to check for any brake system-related trouble codes.

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

•Jack and jack stands
•Lug wrench
•Torque wrench
•Run-out gauge

Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Tools Required: Jack and jack stands, lug wrench, torque wrench, run-out gauge, brake pad thickness gauge.

2. Remove Wheel

Loosen the lug nuts on the affected wheel while vehicle is on the ground.
Lift the vehicle using a jack and securely place jack stands underneath.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Use a run-out gauge to measure rotor run-out. If it exceeds manufacturer specifications, replace the rotor.
- Clean the rotor surface with brake cleaner if no replacement is needed.
Inspect Brake Pads:
- Check for uneven wear or thickness. Replace if below the minimum thickness (typically 3-4 mm).
Replace Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully lift the caliper off the rotor and support it with a bungee cord (do not hang it by the brake line).
- Remove old brake pads and install new ones, ensuring proper orientation.

4. Reassemble

Reinstall the caliper and torque the bolts to specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specification (usually around 75-85 ft-lbs).

5. Test Drive

Conduct a test drive to check for improvements in braking performance and to confirm that the shaking has been resolved.
