Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Refill Brake Fluid

Open the hood and locate the brake master cylinder.
Check the brake fluid level; if low, top off with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated (dark or dirty), it may need to be replaced.

3. Check for Leaks

Visually inspect the brake lines, hoses, and calipers for any signs of fluid leaks.
If leaks are found, replace the damaged components (lines, hoses, or calipers).

4. Bleed the Brake System

Begin at the furthest wheel from the master cylinder (usually the passenger rear).
Use a brake bleeder kit or helper to pump the brake pedal while opening the bleeder valve on the caliper.
Close the valve before releasing the pedal and repeat until no air bubbles are present.
Move to the next wheel and repeat the process until all wheels have been bled.

5. Inspect and Replace Brake Components

Remove the wheel to access the brakes.
Inspect brake pads for thickness; replace if worn beyond specifications (usually 3mm).
Check rotors for warping or scoring; resurface or replace as necessary.

6. Test Brake Booster and Master Cylinder

With the engine off, pump the brake pedal several times to deplete vacuum.
Hold the pedal down and start the engine; the pedal should drop slightly if the booster is functioning correctly.
If the pedal does not drop, the brake booster may need replacement.
Inspect the master cylinder for leaks and replace if necessary.
