Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Check and Top Off Brake Fluid

Tools Required: Brake fluid, funnel
Open the hood and locate the master cylinder reservoir.
Check the brake fluid level; if low, add the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).
Close the reservoir cap securely.

3. Inspect for Leaks

Tools Required: Flashlight
Visually inspect brake lines, calipers, and the master cylinder for any signs of fluid leaks.
If leaks are found, replace the damaged components as necessary.

4. Bleed the Brake Lines

Tools Required: Brake bleeder kit, wrench, brake fluid
Locate the bleeder valve on each brake caliper.
Start from the wheel farthest from the master cylinder (right rear) and work towards the closest (left front).
Attach the bleeder kit and have an assistant slowly press the brake pedal while you open the bleeder valve to release air and fluid.
Close the valve before the pedal is released. Repeat until fluid runs clear without bubbles.
Check and top off the brake fluid level as needed after bleeding each caliper.

5. Inspect Brake Components

Tools Required: Jack, jack stands, lug wrench
Lift the vehicle and remove the wheels to access the brake components.
Inspect brake pads for thickness; replace if worn below the manufacturer’s specification.
Check rotors for warping or excessive wear; machine or replace as required.

6. Test Brake Booster

Tools Required: Vacuum gauge (optional)
Start the engine and press the brake pedal a few times to check for a firm feel; it should not feel spongy.
If the pedal remains spongy, check for vacuum leaks in the brake booster hose and ensure the booster is functioning properly.
