Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface, and engage the parking brake.
•Wear safety glasses and gloves.
•Disconnect the battery before working on any electrical systems related to braking.
•Allow the brake components to cool before handling to avoid burns.

Symptoms

•Steering wheel vibrates when braking
•Brake pedal pulsates during braking
•Increased stopping distance
•Noise from brakes (grinding or squeaking)
•Uneven tire wear

Diagnostic Steps

1
Inspect brake pads and rotors for wear and damage using visual inspection.
2
Check for warping of brake rotors by measuring thickness with a micrometer.
3
Verify brake caliper function by ensuring they are not sticking or malfunctioning.
4
Examine suspension components, including control arms and bushings, for wear or damage.
5
Inspect tire condition for uneven wear or damage.
6
Scan for error codes using an OBD-II scanner to rule out electronic issues.

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

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake pad spreader, micrometer, socket set, torque wrench.
Safety Warnings: Ensure the vehicle is on a flat surface, and engage the parking brake. Wear safety glasses and gloves.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and securely place jack stands.
Remove the wheel completely.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Check for thickness; replace if below manufacturer's specifications (typically 3mm).
Inspect Rotors:
- Use a micrometer to measure rotor thickness. Replace if warped (greater than 0.002 inches) or below minimum thickness.
- If rotors are within specifications but warped, consider resurfacing them.
Brake Calipers:
- Ensure calipers are functioning properly and are not sticking. Clean and lubricate sliding pins if necessary.

4. Reassemble Components

Reinstall the brake pads and rotor (if replaced).
Reattach the wheel and hand-tighten lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).

5. Test Brake System

Press the brake pedal several times to ensure the pads seat correctly.
Perform a test drive to confirm that the shaking issue has been resolved.
