Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, brake bleeder kit, wrench.
Check the brake fluid level; if low, top it up with the recommended brake fluid type (DOT 3 or DOT 4, as specified by the manufacturer).
If the fluid is discolored, consider a full brake fluid flush.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing.
Start with the wheel farthest from the master cylinder (right rear, left rear, right front, left front).
Attach the clear tubing to the bleeder valve on the brake caliper.
Open the bleeder valve and have an assistant press the brake pedal down slowly.
Close the valve before they release the pedal to prevent air from entering back into the system.
Repeat until no air bubbles are visible in the tubing.
Check fluid levels regularly during the process to ensure the master cylinder does not run dry.

4. Inspect and Replace Brake Pads and Rotors (if worn)

Tools Required: Socket set, torque wrench, brake cleaner, shop towels.
Remove the wheel and inspect the brake pads and rotors for wear.
If pads are worn below the minimum thickness, replace them.
If rotors are scored or below the minimum thickness, replace them as well.
Clean the rotor surface with brake cleaner before installation.

5. Test Brake Booster

Tools Required: Vacuum gauge (optional).
With the engine off, press the brake pedal several times to deplete the vacuum.
Start the engine; the brake pedal should drop slightly, indicating the booster is functioning.
