Solution

1. Preparation

Gather all necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel.
Open the master cylinder reservoir cap.
Inspect the fluid level; if low, top up with the recommended brake fluid (usually DOT 3 or DOT 4).
Reinstall the reservoir cap securely.

3. Inspect Brake Lines and Connections

Tools Required: Wrench set, flashlight.
Visually inspect all brake lines for signs of leaks, rust, or damage.
Tighten any loose connections and replace any damaged lines or fittings.

4. Replace Brake Pads and Rotors (if necessary)

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench.
Lift the vehicle and remove the wheel using the lug wrench.
Remove the caliper bolts and slide the caliper off the rotor.
Remove the old brake pads and inspect the rotors for wear. Replace if necessary.
Install new brake pads and reassemble the caliper. Ensure all bolts are torqued to manufacturer specifications.

5. Test the Brake Booster

Tools Required: Vacuum gauge (optional).
Start the engine and check if the brake pedal feels firm after pumping it several times.
If the pedal remains low, the brake booster may need replacement.
