⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery when working on the braking system.
•Allow the brakes to cool before performing any inspection or repair to avoid burns.

Symptoms

•Vibration felt through the brake pedal
•Steering wheel shakes during braking
•Uneven wear on brake pads or rotors
•Increased stopping distance
•Noise (grinding or squeaking) when braking
•Brake warning light illuminated on the dashboard

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a run-out gauge.
2
Check brake pads for thickness and signs of uneven wear.
3
Examine brake calipers for proper function and sticking.
4
Inspect suspension components (e.g., control arms, bushings) for wear or damage.
5
Test the wheel alignment to ensure it is within manufacturer specifications.
6
Scan for any diagnostic trouble codes (DTCs) using an OBD-II scanner.

Solution

Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, brake cleaner, safety glasses, and gloves.
Ensure the vehicle is parked on a level surface, and engage the parking brake.

2. Remove Wheel Assembly

Loosen the lug nuts on the wheel using a socket wrench.
Lift the vehicle using a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Check rotor surface for warping or scoring.
- If warped, replace with new rotors.
Inspect Brake Pads:
- Measure pad thickness; replace if worn below manufacturer specifications.
- Clean the caliper and bracket area with brake cleaner.
Replace Components if Necessary:
- If rotors or pads are replaced, follow proper installation procedures:
  1. Remove the caliper by unscrewing the caliper bolts (torque to manufacturer specifications upon reinstallation).
  2. Install new brake pads, ensuring proper orientation.
  3. Install new rotors if required, using the torque wrench to tighten the retaining screws to the specified torque.

4. Reassemble Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Tighten the lug nuts in a star pattern using a torque wrench to the specified value.

5. Test Brake System

Start the vehicle and pump the brakes to ensure proper pedal feel.
Conduct a controlled test drive to check for vibrations during braking.
