Diagnostic Steps

Solution

1. Preparation

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

2. Inspect and Top Off Brake Fluid

Open the hood and locate the brake master cylinder reservoir.
Check the brake fluid level; if low, add the recommended brake fluid (DOT 3 or DOT 4).
If fluid is contaminated (dark or dirty), consider a complete brake fluid flush.

3. Check for Leaks

Visually inspect brake lines, calipers, and wheel cylinders for any signs of brake fluid leakage.
If leaks are found, replace the affected components (e.g., brake lines or calipers) as necessary.

4. Bleed the Brake System

Start at the wheel farthest from the master cylinder (usually the passenger rear).
1. Attach a clear plastic hose to the bleeder screw on the brake caliper.
2. Submerge the other end in a container with brake fluid.
3. Have an assistant press the brake pedal several times and hold it down.
4. Open the bleeder screw to release air and fluid, then close it before the pedal is released.
5. Repeat until clear fluid flows without bubbles.
6. Move to the next wheel and repeat the process (passenger front, driver rear, driver front).

5. Inspect the Brake Booster

Check the brake booster for proper operation:
1. With the engine off, pump the brake pedal several times to deplete vacuum.
2. Hold the pedal down and start the engine; the pedal should drop slightly if the booster is functioning.

6. Verify and Replace the Master Cylinder (if necessary)

If the pedal still feels soft after bleeding the brakes, test the master cylinder:
1. Remove the master cylinder from the brake booster.
2. Inspect for internal leaks and replace if necessary.
