⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the braking system if electronic components are involved.
•Allow the brakes to cool before working on them to avoid burns.

Symptoms

•Pulsation felt in the brake pedal when applying the brakes
•Vibration in the steering wheel during braking
•Increased stopping distance
•Noisy brakes (squeaking or grinding)
•Possible brake warning light illuminated on the dashboard

Diagnostic Steps

1
Inspect brake rotor surfaces for warping or scoring using a dial indicator.
2
Check brake pads for uneven wear or damage.
3
Measure rotor thickness to ensure it is within manufacturer specifications.
4
Verify brake caliper operation and ensure they are not sticking.
5
Inspect brake fluid for contamination or low levels.
6
Test drive the vehicle to confirm the pulsation is present under various braking conditions.

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

Solution

1. Preparation

Gather tools and parts required for the repair.
Raise the vehicle using a hydraulic lift or jack stands and remove the wheels.
Safety Warning: Ensure the vehicle is securely supported before working underneath.

2. Remove Brake Components

Brake Caliper Removal:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord or wire to avoid stress on the brake line.
Brake Pad Removal:
- Remove the brake pads from the caliper bracket by sliding them out.

3. Inspect and Replace Rotors

Rotor Inspection:
- Check the rotors for warping using a dial indicator.
- If warped or below minimum thickness, proceed to replace the rotors.
Rotor Replacement:
- Remove the rotor by unscrewing the retaining screw (if applicable) and sliding it off the hub.
- Clean the hub surface with a wire brush to remove rust or debris.
- Install new rotors, ensuring they are seated properly.

4. Install New Brake Pads

Apply brake grease to the back of the new pads to prevent noise.
Slide the new pads into the caliper bracket, ensuring they are oriented correctly.

5. Reassemble Brake Components

Reattach the brake caliper over the new pads.
Tighten the caliper mounting bolts to the manufacturer's specified torque value (usually around 20-30 ft-lbs).

6. Final Checks

Reinstall wheels and lower the vehicle.
Pump the brake pedal several times to ensure proper pad seating and restore brake pressure.
Check brake fluid level and top off if necessary.
