⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the brakes to cool before working on them to avoid burns.
•Ensure the vehicle is securely supported by jack stands before working underneath.

Symptoms

•Grinding noise when applying brakes
•Vibration or pulsation felt through the brake pedal
•Reduced braking efficiency
•Warning lights on the dashboard (if applicable)
•Burning smell from the wheels (in severe cases)

Diagnostic Steps

1
Inspect brake pads for wear and tear using a visual inspection.
2
Check brake rotors for scoring, warping, or damage.
3
Examine calipers for proper operation and any signs of sticking.
4
Test brake fluid levels and condition.
5
Listen for noise with the vehicle stationary and in motion to confirm source.
6
Inspect brake hardware, including shims and clips, for proper installation and condition.

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

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set and take off the wheel.

3. Inspect and Remove Brake Components

Remove Caliper:
- Use a socket wrench to remove caliper bolts.
- Carefully slide the caliper off the rotor, supporting it to avoid strain on the brake line.
Remove Brake Pads:
- Slide out the existing brake pads from the caliper bracket.
- Check for wear indicators; if worn down to the metal, replacement is necessary.
Inspect Rotor:
- Measure rotor thickness with a micrometer; replace if below minimum specifications.
- Check for any grooves or scoring; if significant, resurfacing or replacement is necessary.

4. Install New Components

Install New Brake Pads:
- Apply brake grease to the backing of the new pads to prevent noise.
- Insert the new brake pads into the caliper bracket.
Reinstall Caliper:
- Slide the caliper back over the new pads and align it with the rotor.
- Secure it with the caliper bolts, tightening to manufacturer specifications (usually around 25-30 ft-lbs).
Install Rotor (if replaced):
- If the rotor was replaced, ensure it is properly seated on the hub and secured.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts to the specified torque (typically 100-120 ft-lbs).
Reconnect the negative battery terminal.
