⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Always wear safety glasses and gloves when working on brakes.
•Allow brakes to cool down before handling components after driving.

Symptoms

•Grinding noise during braking
•Reduced braking efficiency
•Vibration or pulsation in the brake pedal
•Brake warning light illuminated
•Increased stopping distance

Diagnostic Steps

1
Inspect brake pads for wear: Check the thickness of the brake pads through the wheel openings.
2
Check brake rotors for damage: Look for scoring, warping, or excessive wear on the rotors.
3
Examine brake calipers: Ensure calipers are functioning properly and not sticking.
4
Inspect brake fluid level: Verify that the brake fluid is at the correct level in the master cylinder.
5
Scan for error codes: Use an OBD-II scanner to check for any fault codes related to the brake system.

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 tools and parts required for the brake service.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Safety warning: Disconnect the battery before working on electrical components.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the brake rotor. Support it with a bungee cord or hang it to avoid strain on the brake line.
Inspect brake pads for wear; replace if the thickness is below 3mm.
- Sub-step: Install new brake pads, ensuring proper orientation.
Reinstall the caliper, tightening the bolts to the manufacturer’s torque specifications (typically around 20-25 lb-ft).

4. Inspect and Replace Rotors (if necessary)

If rotors are damaged, remove them by taking off the rotor retaining screws (if applicable).
Install new rotors: Clean the surface with brake cleaner to remove any protective coating.
Reinstall the rotor and secure it with retaining screws.

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 (typically around 100-150 lb-ft).
Reconnect the battery if it was disconnected.
Pump the brake pedal several times to seat the pads against the rotors.
