Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow brakes to cool before inspection to avoid burns.

Symptoms

•Vibration or shaking felt through the steering wheel when braking
•Pulsating brake pedal during braking
•Increased stopping distance
•Unusual noise from the brakes (squealing or grinding)
•Uneven wear on brake pads or rotors
•Vehicle pulling to one side during braking

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for thickness and even wear.
3
Examine brake calipers for proper function and any signs of sticking.
4
Inspect wheel lug nut torque and alignment.
5
Test drive the vehicle to replicate the shaking and note any specific conditions (speed, braking force).
6
Scan the vehicle's computer for any related error codes that might indicate issues with the ABS or traction control systems.

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

•Lug wrench
•Jack and jack stands
•Dial indicator
•Brake caliper tool
•Torque wrench
•Basic hand tools (socket set, wrenches)

Parts Required

•Brake rotors (if warped)
•Brake pads (if worn)

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Wheel Removal

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

3. Brake Inspection

Check Rotors:
- Use a dial indicator to measure rotor runout; replace if warped beyond specifications (usually more than 0.002 inches).
- Inspect the rotor surface for scoring or pitting.
Check Brake Pads:
- Inspect the thickness of the brake pads; replace if below manufacturer specifications.
- Look for uneven wear patterns indicating caliper issues.

4. Brake Component Replacement

If Rotors are Warped:
- Remove the caliper by unscrewing the caliper bolts.
- Hang the caliper using a wire to avoid strain on the brake line.
- Remove the old rotor and clean the hub surface.
- Install the new rotor, ensuring it is properly seated.
- Reattach the caliper using new caliper bolts if specified by the manufacturer.
If Brake Pads are Worn:
- Remove the caliper (as described above).
- Replace the pads with new ones, ensuring correct orientation and seating.
- Compress the caliper piston using a brake caliper tool before reinstallation.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer's specifications.
Reconnect the battery.
Test drive the vehicle to ensure the shaking issue has been resolved.
