⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the brake system to prevent accidental deployment of any electronic features.
•Allow brake components to cool before handling to avoid burns.

Symptoms

•Grinding noise when applying brakes
•Vibration in the brake pedal
•Decreased braking efficiency
•Visual wear on brake pads or rotors
•Brake warning light illuminated on the dashboard

Diagnostic Steps

1
Inspect the brake pads for wear and tear using a visual inspection.
2
Check for any debris or foreign objects lodged between the brake pad and rotor.
3
Measure rotor thickness with a micrometer to determine if they are below the minimum specifications.
4
Examine brake fluid level and condition in the master cylinder.
5
Listen for noise during a test drive to confirm the location and type of noise.

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

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly before lifting the vehicle.
Remove the lug nuts completely and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check thickness of brake pads; replace if less than 3mm.
- Look for uneven wear or damage.
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it without straining the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they fit snugly in the caliper bracket.

4. Inspect and Resurface or Replace Rotors

Inspect Rotors:
- Check for scoring, rust, or excessive wear.
Resurface or Replace:
- If rotors are within specifications, use a brake lathe to resurface them.
- If they are below the minimum thickness, replace the rotors with new ones.

5. Reassemble and Test

Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications.
Reattach the wheel and torque the lug nuts in a star pattern.
Lower the vehicle and pump the brake pedal to seat the pads before test driving.
