Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems.
•Allow brakes to cool before handling components after driving.

Symptoms

•Pulsating brake pedal during braking
•Vibration felt through the steering wheel
•Increased stopping distance
•Grinding noise when braking
•Brake warning light illuminated (if applicable)

Diagnostic Steps

1
Inspect brake rotors visually for warping or uneven wear.
2
Check brake pad thickness to ensure they are not worn down.
3
Lift the vehicle and spin each wheel to listen for abnormal noises or resistance.
4
Use a dial indicator to measure rotor runout.
5
Scan for any error codes related to the braking system using an OBD-II scanner.

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

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery (negative terminal) for safety.

2. Remove Wheel

Using a jack, lift the front or rear of the vehicle (where pulsation is felt).
Secure with jack stands.
Remove the wheel using a socket set.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove caliper bolts using a socket wrench.
- Lift the caliper off the rotor without disconnecting the brake line.
- Check the thickness of the brake pads; if less than 3mm, replace.
Replace Brake Pads (if necessary):
- Use a brake pad spreader to push the caliper piston back.
- Install new brake pads into the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Inspect Rotors:
- Use a dial indicator to measure rotor runout.
- If runout exceeds specifications (usually 0.002 inches), rotors are likely warped.
Resurface Rotors (if applicable):
- Remove rotor retaining screws.
- Use a rotor lathe to resurface (if within thickness limits).
Replace Rotors (if necessary):
- Remove the old rotor and install a new one, ensuring it is properly seated.

5. Reassemble and Test

Reattach the caliper and secure with bolts to manufacturer’s torque specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and torque the lug nuts to manufacturer specifications (typically around 100-120 ft-lbs).
Reconnect the battery.
Lower the vehicle and pump the brake pedal to seat the new pads and check for firmness.
