Diagnostic Steps

1
Inspect the brake fluid reservoir for low fluid level and color condition.
2
Check for leaks in brake lines, brake calipers, and wheel cylinders.
3
Examine the brake pads and rotors for excessive wear.
4
Test the brake master cylinder for internal leaks.
5

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Wear safety gloves and goggles.

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Remove the cap and visually inspect the fluid level.
- If low, proceed to refill with the appropriate brake fluid type (DOT 3 or DOT 4, as specified in the owner's manual).

3. Inspect for Leaks

Visually inspect the entire brake system:
- Brake lines for cracks or damage.
- Brake calipers for signs of fluid leakage.
- Wheel cylinders and master cylinder for leaks.
If leaks are found, replace the damaged components.

4. Replace Brake Fluid (if contaminated)

If the fluid is dirty or contaminated, drain the old fluid:
- Locate the brake bleeder screws on each caliper.
- Use a wrench to open the bleeder screw and let the old fluid drain into a container.
Refill the reservoir with new brake fluid.

5. Bleed the Brake System

Start with the wheel furthest from the master cylinder (typically the rear passenger side).
Attach a clear hose to the bleeder screw and submerge it in a container.
Have an assistant press the brake pedal several times and hold it down.
Open the bleeder screw to allow air and fluid to escape, then close the screw before the pedal is released.
Repeat this process for each wheel in the following order: rear passenger, rear driver, front passenger, front driver.
