⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety glasses and gloves when working on the braking system.
•Allow the vehicle’s braking components to cool before touching them after driving.

Symptoms

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

Diagnostic Steps

1
Inspect brake pads for wear and tear using a visual examination.
2
Check brake rotor surfaces for scoring or uneven wear.
3
Listen for noise while applying the brakes at low speeds.
4
Use a brake caliper tool to assess caliper movement and function.
5
Scan for any error codes related to the braking system using an OBD-II scanner.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Tools Required: Lug wrench, jack, jack stands.
Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using the jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the brake caliper bolts using a socket wrench.
Carefully slide the caliper off the brake rotor, supporting it to avoid damaging the brake line.
Inspect the brake pads for wear. If they are worn down to the backing plate, replace them.
- Parts Required: New brake pads.
Slide new brake pads into the caliper bracket, ensuring they are positioned correctly.

4. Inspect and Resurface/Replace Rotors

Check the brake rotors for scoring or grooves. If they are damaged, either resurface or replace them.
- Parts Required: New rotors (if needed).
If resurfacing, use a rotor lathe to achieve a smooth surface.
If replacing, remove the old rotor by unscrewing the retaining screws and sliding the new rotor onto the hub.

5. Reassemble Braking System

Place the caliper back over the new brake pads and rotor.
Reinstall the caliper bolts and tighten to the manufacturer’s torque specifications (typically around 85-100 lb-ft, check vehicle manual).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle off the jack stands using the jack.
Tighten the lug nuts in a criss-cross pattern to the manufacturer’s specifications.
Reconnect the negative battery terminal.
