Solution

1. Preparation

Tools Required: OBD-II scanner, brake fluid, socket set, jack and jack stands, brake cleaner, torque wrench, safety glasses, gloves.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported before working. Wear safety glasses and gloves.

2. Addressing Brake Fluid Issues

Check and Top Off Brake Fluid: If low, add the appropriate brake fluid type (DOT 3 or DOT 4 as specified in the owner’s manual).
Inspect for Leaks: If the fluid was low, trace the brake lines and hoses for leaks. Repair or replace any damaged components as necessary.

3. Replacing Brake Pads and Rotors

Remove Wheel: Use a jack to lift the vehicle and secure it with jack stands. Remove the wheel using a socket set.
Remove Brake Caliper: Unbolt the brake caliper and remove it from the rotor. Hang it securely using a wire to avoid stress on the brake line.
Replace Brake Pads: Remove the old brake pads from the caliper bracket, install new pads, and ensure they are properly seated.
Replace Rotor: If the rotor is damaged or worn, unbolt it and replace it with a new rotor. Ensure the new rotor is cleaned with brake cleaner before installation.
Reassemble: Reattach the brake caliper and wheel, torque bolts to the manufacturer’s specifications.

4. Testing Brake Booster

Perform Vacuum Test: With the engine off, pump the brake pedal several times to deplete vacuum. Start the engine and press the brake pedal; it should feel firm and then sink slightly.
Replace Brake Booster (if necessary): If the pedal does not respond correctly, the brake booster may need replacement.
