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.
•Allow the brakes to cool before inspection to prevent burns.

Symptoms

•Steering wheel shakes or vibrates when braking
•Pulsation felt through the brake pedal
•Uneven wear on brake pads or rotors
•Increased stopping distance
•Grinding noise when brakes are applied

Diagnostic Steps

1
Inspect brake rotors for warping or irregularities using a dial indicator.
2
Check brake pad thickness and condition.
3
Verify the alignment and condition of suspension components (e.g., control arms, tie rods).
4
Examine wheel balance and tire condition for any abnormal wear.
5
Scan for any error codes that may indicate electronic brake system issues.
6
Test brake fluid for moisture content to ensure it's not contaminated.

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

Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Gather safety gear (gloves, goggles) and make sure the vehicle is cooled down.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the braking system.

3. Inspect Brake Components

Rotors: Measure rotor thickness and check for warping. If warping is above manufacturer specifications, replace the rotors.
Brake Pads: Check the pads for uneven wear. Replace if they are worn below the minimum thickness.
Calipers: Ensure calipers are functioning properly and not seizing. Clean or replace as needed.

4. Replace Rotors and Pads (if necessary)

Rotors:
- Remove the caliper and bracket.
- Unbolt the old rotor and replace it with a new one.
- Torque the rotor to the manufacturer’s specifications (typically around 80-100 ft-lb).
Brake Pads:
- Slide new brake pads into the caliper bracket.
- Reattach the caliper over the pads and torque the caliper bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (usually around 100-110 ft-lb).
Test drive the vehicle gently to ensure that the shaking has been resolved.
