Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety gloves and goggles to protect against brake fluid.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid (DOT 3 or DOT 4, as specified by the manufacturer)
Locate the master cylinder reservoir.
Remove the cap and check the fluid level; if low, add the appropriate brake fluid to the maximum fill line.

3. Inspect and Repair Leaks

Tools Required: Wrench set, brake line repair kit (if needed)
Visually inspect all brake lines, fittings, and components for signs of leaks or damage.
If leaks are found, replace the damaged components using the appropriate repair kit or replace the entire line as necessary.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container
Connect clear tubing to the bleeder valve on the brake caliper.
Have an assistant press the brake pedal while you open the bleeder valve to release air and fluid until no more bubbles appear.
Close the valve and repeat for all calipers, starting from the furthest from the master cylinder.
Ensure to keep the master cylinder reservoir filled during the process.

5. Test Brake Booster

Tools Required: Vacuum gauge (optional)
With the engine off, pump the brake pedal several times to deplete the vacuum.
Start the engine and press the brake pedal; it should feel firmer and less spongy if the booster is functioning properly.

6. Final Assembly and Test

Reassemble any components you may have removed during inspection or repair.
Test drive the vehicle at a low speed to ensure the brakes are functioning correctly and the pedal feel is firm.
