Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Remove the cap and check the brake fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the recommended DOT brake fluid.

3. Inspect for Leaks

Visually inspect all brake lines for cracks or corrosion.
Check the brake calipers and wheel cylinders for any signs of leakage.
If leaks are found, replace the affected components and bleed the brake system.

4. Replace Worn Components

If brake pads are worn, remove the wheel and brake caliper.
Replace the brake pads if they are below the manufacturer’s minimum thickness.
Inspect the rotors; if they are warped or below specification, replace them as necessary.

5. Brake Booster Check

Ensure the brake booster is functioning correctly by applying pressure to the pedal with the engine off.
Start the engine while maintaining pressure; the pedal should drop slightly. If it doesn’t, the booster may need replacement.

6. Master Cylinder Inspection

If all other components are in good condition, test the master cylinder.
Remove the master cylinder from the vehicle.
Perform a pressure test to ensure it holds pressure without leaking.
Replace if it fails the test or shows signs of wear.
