Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Allow brakes to cool before inspection or replacement.

Symptoms

•Vehicle shakes or vibrates when brakes are applied
•Steering wheel shudders during braking
•Increased stopping distance
•Uneven brake pad wear
•Possible burning smell from brakes after prolonged use

Diagnostic Steps

1
Inspect brake components visually for any signs of wear or damage.
2
Check brake rotor thickness using a micrometer to ensure they are within manufacturer specifications.
3
Scan for any error codes using an OBD-II scanner to identify potential sensor issues.
4
Perform a wheel alignment check to detect any misalignment that could contribute to shaking.
5
Test the brake fluid for moisture content and contamination.
6
Examine suspension components (e.g., control arms, bushings) for wear or play.

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 tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors (if necessary)

Inspection:
- Check rotors for warping or uneven wear.
- Measure rotor thickness with a micrometer; replace if below minimum specification.
Replacement:
- Remove caliper bolts using a socket set and remove the caliper.
- Hang the caliper using a wire to avoid straining the brake line.
- Remove the rotor by unscrewing any retaining screws, if present.
- Install new rotors, ensuring they are free of grease or oil.
- Reattach the caliper and torque bolts to the manufacturer’s specifications.

4. Replace Brake Pads (if necessary)

Remove old brake pads from the caliper bracket.
Inspect the caliper piston for damage and push it back using a C-clamp.
Install new brake pads, ensuring they fit snugly in the bracket.
Apply brake grease to backing plates to reduce noise.

5. Reassemble and Reinstall Wheel

Reattach the wheel, tightening lug nuts by hand.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications in a star pattern.
