Solution

1. Preparation

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

2. Inspect Brake Lines and Hoses

Tools Required: Flashlight
Visually inspect all brake lines and hoses from the master cylinder to the calipers.
Look for cracks, corrosion, or damaged sections that could indicate a leak.
If damage is found, proceed to replace the affected brake line or hose.

3. Check Brake Calipers and Wheel Cylinders

Tools Required: Jack and jack stands, wrench set
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to gain access to the brake components.
Inspect the brake calipers for any fluid leaks, particularly around the seals.
Check the wheel cylinders in drum brakes for similar issues.
If leaks are detected, replace the caliper or wheel cylinder as necessary.

4. Inspect the Master Cylinder

Tools Required: Wrench set
Locate the master cylinder, usually found near the brake fluid reservoir.
Check for any signs of fluid leaking from the master cylinder body or around the piston seals.
If leakage is found, replace the master cylinder.

5. Test and Refill Brake Fluid

After addressing any leaks, refill the brake fluid reservoir with the recommended brake fluid type (usually DOT 3 or DOT 4).
Bleed the brake system to remove any air that may have entered during repairs.
Use a brake bleeder kit if necessary.
