⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Allow brake components to cool before handling to avoid burns.

Symptoms

•Vibration felt through the steering wheel during hard braking
•Pulsating brake pedal feedback
•Increased stopping distance
•Possible noise (grinding or squeaking) when braking
•Uneven brake pad wear or rotor damage

Diagnostic Steps

1
Inspect brake rotors for warping or damage by measuring runout with a dial indicator.
2
Check brake pads for uneven wear or contamination.
3
Examine brake calipers for proper operation and possible sticking.
4
Verify brake fluid levels and condition; check for air in the brake lines.
5
Inspect wheel bearings for play or wear that may cause vibrations.

Diagnostic Steps

1
Inspect brake rotors for warping or damage by measuring runout with a dial indicator.
2
Check brake pads for uneven wear or contamination.
3
Examine brake calipers for proper operation and possible sticking.
4
Verify brake fluid levels and condition; check for air in the brake lines.
5
Inspect wheel bearings for play or wear that may cause vibrations.

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Remove Wheel

Tools Required: Socket set, torque wrench.
Loosen the lug nuts on the affected wheel.
Lift the vehicle with a jack and secure it on jack stands.
Remove the wheel to access the braking components.

3. Inspect and Replace Brake Rotors

Check the rotors for warping using a dial indicator.
If warped beyond specifications, remove the rotors:
- Unscrew the caliper bolts and remove the caliper from the rotor.
- Hang the caliper using a bungee cord to avoid stressing the brake line.
Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
Install new rotors, ensuring they are clean and free of grease.
Torque the rotor retaining screws to the manufacturer's specifications.

4. Inspect and Replace Brake Pads

Remove the brake pads by unbolting them from the caliper bracket.
Inspect for uneven wear; replace if necessary.
Apply brake grease to the backing of the new pads and install them in the caliper bracket.
Reattach the caliper over the new pads.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Pump the brake pedal to seat the pads against the rotors.
Test drive the vehicle to ensure the issue is resolved.
