Diagnostic Steps

Solution

1. Preparation

Tools Required: Socket set, brake fluid, brake bleeding kit, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake and wear safety goggles and gloves.

2. Inspect and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
If the fluid level is low, fill it to the recommended level with the appropriate brake fluid type (DOT 3 or DOT 4 as per the owner's manual).
Check for any signs of leaks around the reservoir.

3. Bleed the Brake System

Tools Required: Brake bleeding kit, clear tubing.
Attach the clear tubing to the bleeder valve on the farthest brake caliper from the master cylinder.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and old fluid; close the valve before releasing the pedal.
Repeat the process until clear fluid without air bubbles flows out, then move to the next caliper in order.
Ensure to check and refill the brake fluid reservoir frequently during this process.

4. Inspect and Replace Brake Components (if necessary)

If sponginess persists, inspect brake pads and rotors for wear.
Replace any worn or damaged components, ensuring proper torque specifications are followed (generally 20-25 ft-lbs for caliper bolts).
Use quality replacement parts compatible with the vehicle.
