Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles to protect from brake fluid.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the “MIN” and “MAX” marks on the reservoir.
If low, visually inspect the reservoir for cracks or damage.

3. Examine Brake Lines

Follow the brake lines from the master cylinder to the wheels.
Look for any signs of deterioration, corrosion, or wetness.
If damage is found, mark the affected area for replacement.

4. Check Brake Calipers

Inspect each brake caliper for signs of fluid leaking around the piston seal.
Clean any visible dirt or debris for better visibility.
If fluid is present, the caliper may need to be rebuilt or replaced.

5. Inspect Master Cylinder

Check the master cylinder for any signs of leakage, especially around the seals.
Remove the cap and inspect the inside for moisture or debris.
If leaking, the master cylinder may require replacement.

6. Final Steps

Clean up any spilled brake fluid immediately using a suitable cleaner.
Refill the brake fluid reservoir to the correct level if necessary.
Ensure all components are secured and close the hood.
