Solution

1. Preparation

Gather necessary tools and parts for the inspection.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear gloves and safety glasses to protect yourself from brake fluid.

2. Check Brake Fluid Reservoir

Locate the brake fluid reservoir (usually near the back of the engine bay).
Remove the cap and check the fluid level against the "MIN" and "MAX" indicators.
If low, inspect for leaks, as detailed below.

3. Inspect Brake Lines and Hoses

Follow the brake lines from the master cylinder to each wheel.
Look for signs of corrosion, cracks, or wetness along the length of the lines.
Check the rubber hoses for bulges or signs of deterioration.

4. Examine Brake Calipers and Wheel Cylinders

Inspect each brake caliper for fluid seepage around the piston area.
Check the wheel cylinders (for rear drum brakes) for any leaks.
If fluid is found, identify the source and prepare for replacement.

5. Inspect Master Cylinder

Check the master cylinder for any signs of fluid leakage around the seals.
Ensure that all connections to the brake lines are tight and secure.
If the master cylinder is leaking, it may need to be rebuilt or replaced.

6. Clean and Test

If any leaks are found, clean the affected areas with brake cleaner.
Refill the brake fluid reservoir to the proper level.
Test the brake pedal feel after addressing any leaks.
