Solution

1. Preparation

Tools Required: Jack and jack stands, wrench set, brake bleeder kit, OBD-II scanner, container for old brake fluid.
Safety Warnings: Ensure the vehicle is on a flat surface and properly secured with jack stands. Wear safety glasses and gloves.

2. Check and Refill Brake Fluid

Inspect the brake fluid reservoir cap and remove it.
Assess the fluid level; if low, top off with the appropriate brake fluid type (usually DOT 3 or DOT 4).
Replace the cap securely.

3. Bleed the Brake System

Connect the brake bleeder kit to the brake caliper’s bleeder valve.
Have an assistant pump the brake pedal several times until firm, then hold the pedal down.
Open the bleeder valve to let fluid escape until the pedal sinks, then close the valve before the pedal is released.
Repeat this process for each wheel, starting from the one farthest from the master cylinder (typically passenger rear, driver rear, passenger front, driver front).
Monitor the brake fluid level and top off as needed during the process.

4. Inspect and Replace the Master Cylinder (if necessary)

If bleeding does not resolve the issue, remove the master cylinder:
- Disconnect the brake lines using the appropriate wrench.
- Unbolt the master cylinder from the brake booster.
- Install the new master cylinder by reversing the removal process.
- Ensure to properly torque the bolts to manufacturer specifications.

5. Final Assembly and Testing

Recheck all brake fluid levels after the brake system is reassembled.
Test the brake pedal feel to confirm it is no longer spongy.
Conduct a short test drive to check for braking effectiveness and any abnormal noises.
