Symptoms

•Brake warning light illuminated on the dashboard

•Unusual noises when braking, such as squeaking or grinding

•Reduced braking responsiveness or increased stopping distance

•Vibration or pulsation in the brake pedal during application

•Brake fluid leakage around wheels or under the vehicle

•Warning message on the display indicating service required for brakes

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues while working on the brake system.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Remove caliper mounting bolts using a socket set.
3. Carefully slide the caliper off the rotor and support it (do not let it dangle).
4. Remove old brake pads from the caliper bracket.
5. Compare new pads with old ones to ensure correct size.
6. Apply brake grease to the back of the new pads and install them into the caliper bracket.
7. Reinstall the caliper over the new pads and secure with mounting bolts (torque to manufacturer's specifications).

3. Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are worn or damaged, remove them by removing any retaining screws.
2. Clean the hub surface to ensure proper rotor seating.
3. Install new rotors and secure them with retaining screws.
4. Ensure the rotors are free of oil or grease before installing the brake pads.

4. Bleed the Brake System

Sub-steps:
1. Use a brake bleeder kit to remove any air from the brake lines.
2. Start with the wheel farthest from the master cylinder and work your way closer (typically passenger rear, driver rear, passenger front, driver front).
3. Ensure the brake fluid reservoir is filled to the appropriate level throughout the process.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and torque the lug nuts to the specified values.
2. Reconnect the battery.
3. Test the brakes by applying pressure to ensure they are functioning correctly before driving.
