Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely supported on jack stands before working underneath it.
•Allow the brakes to cool before handling brake components.

Symptoms

•Shaking or vibration in the steering wheel during braking
•Pulsation felt in the brake pedal
•Uneven wear on brake pads or rotors
•Possible noise (grinding or squeaking) when braking
•Decreased braking performance or responsiveness

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for wear; measure thickness and look for uneven wear patterns.
3
Examine suspension components (control arms, bushings, and ball joints) for damage or wear.
4
Verify wheel alignment and balance by measuring against manufacturer specifications.
5
Scan for any error codes that might indicate issues with brake-related sensors.

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

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts on the wheel with the braking issue.
Lift the vehicle with a jack and secure it on jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Remove the caliper by unbolting it from the bracket; support it with a bungee cord or rope to avoid stress on the brake line.
Take off the brake pads from the caliper bracket.
Use a dial indicator to check for rotor warping; replace rotors if they exceed manufacturer specifications.
Install new rotors by aligning them with the hub and securing them with appropriate torque (usually between 10-15 ft-lbs, refer to service manual).

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if they are below manufacturer specifications (typically 3mm or less), replace them.
Ensure the caliper bracket is clean and free of debris.
Install new brake pads, ensuring proper orientation and fitment.

5. Reassemble Components

Reinstall the caliper over the new pads and rotor, securing it with bolts to the manufacturer-specified torque (usually around 25-35 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and finish tightening the lug nuts in a criss-cross pattern to the recommended torque (typically 75-90 ft-lbs).

6. Test the Braking System

Pump the brake pedal to ensure proper engagement before driving.
Conduct a test drive to confirm the shaking issue is resolved.
