2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery if working on electrical components.
•Allow brakes to cool before inspection to avoid burns.

Symptoms

•Grinding noise during braking
•Grinding noise when turning or maneuvering
•Vibration felt through the steering wheel or brake pedal
•Reduced braking performance
•Unusual wear on brake pads or rotors
•Noise occurring at specific speeds or conditions

Diagnostic Steps

1
Inspect brake pads and rotors for wear and damage.
2
Check for debris lodged in the brake components or wheel wells.
3
Test drive the vehicle to isolate when the grinding noise occurs (braking, turning, etc.).
4
Inspect wheel bearings and CV joints for wear or damage.
5
Examine suspension components (shocks, struts, bushings) for signs of wear.
6
Use a stethoscope or listening device to pinpoint the noise source.

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

Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and set the parking brake.
Wear appropriate safety gear (gloves, safety glasses).

2. Brake Inspection and Replacement

Sub-steps:
1. Remove Wheel:
  - Loosen lug nuts and lift the vehicle using a jack.
  - Secure with jack stands and remove the wheel.
2. Inspect Brake Pads and Rotors:
  - Check the thickness of the brake pads; replace if below recommended thickness (usually 3 mm).
  - Inspect rotors for grooves or scoring; replace if damaged.
3. Replace Brake Pads:
  - Remove caliper bolts and lift the caliper off the rotor.
  - Remove old brake pads and install new ones.
  - Compress the caliper piston using a brake caliper tool.
  - Reinstall the caliper and torque bolts to the manufacturer’s specifications (typically around 20-30 ft-lbs).
4. Reinstall Wheel:
  - Place the wheel back on and hand-tighten lug nuts.
  - Lower the vehicle and torque lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).

3. Drivetrain and Suspension Inspection

Sub-steps:
1. Check Wheel Bearings:
  - Jack up the vehicle and support with jack stands.
  - Grasp the wheel at 9 and 3 o'clock positions and wiggle; any play indicates worn bearings.
2. Inspect CV Joints:
  - Look for torn boots or grease leakage; replace if necessary.
3. Examine Suspension Components:
  - Inspect shocks and struts for leaks or damage. Replace as needed.
