⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the negative battery terminal if working on electronic brake systems.
•Ensure the vehicle is securely lifted and supported before working underneath.

Symptoms

•Squeaking or squealing noise when braking
•Grinding noise indicating metal-to-metal contact
•Reduced braking effectiveness or spongy brake pedal
•Vibrations felt through the brake pedal
•Warning light on the dashboard for brake maintenance

Diagnostic Steps

1
Inspect the brake pads visually through the wheel spokes to determine wear level.
2
Check the brake fluid level in the reservoir; low levels may indicate wear.
3
Test the brake pedal feel; a spongy pedal may indicate air in the brake lines or worn pads.
4
Examine the rotors for grooves or scoring that could indicate the need for replacement.
5
Verify if there are any dashboard warning lights related to the brake system.

Solution

Solution

1. Preparation

Gather tools and parts:
- Tools: Socket set, torque wrench, C-clamp or brake caliper tool, brake cleaner, and a jack with jack stands.
- Parts: New brake pads, brake grease.
Safety: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety glasses and gloves.

2. Lift the Vehicle

Loosen the lug nuts on the front or rear wheels (depending on which brake pads are being changed).
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the brake components.

3. Remove the Brake Caliper

Locate the caliper bolts (usually two) and remove them using a socket.
Carefully slide the caliper off the brake rotor. Support the caliper with a bungee cord or wire to avoid putting stress on the brake line.

4. Remove Old Brake Pads

Slide the old brake pads out of the caliper bracket.
Inspect the caliper bracket for any debris or corrosion and clean if necessary.

5. Compress the Caliper Piston

Use a C-clamp or brake caliper tool to slowly compress the caliper piston back into the caliper housing. This creates space for the new, thicker brake pads.

6. Install New Brake Pads

Apply a thin layer of brake grease to the back of the new brake pads to prevent squealing.
Slide the new brake pads into the caliper bracket, ensuring they are properly seated.

7. Reinstall the Brake Caliper

Carefully place the caliper back over the new brake pads and rotor.
Reinstall and tighten the caliper bolts to the manufacturer’s specified torque (usually around 30-40 ft-lbs).

8. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the specified torque (typically 76-89 ft-lbs).

9. Test the Brakes

Before driving, pump the brake pedal a few times to ensure the brake pads seat correctly against the rotor.
Check for any unusual noises and ensure proper brake function at low speeds.
