Solution

1. Preparation

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

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, this may indicate a leak.
Clean the area around the reservoir cap to prevent contamination when opening it.

3. Check Brake Lines and Hoses

Follow the brake lines from the master cylinder to the calipers.
Look for any signs of wear, rust, or leaks.
If any hoses are damaged, mark them for replacement.

4. Examine Calipers and Wheel Cylinders

Remove the wheel on the side being inspected.
Inspect the brake caliper for any signs of fluid seeping from the seals.
Look at the wheel cylinder for any signs of leaking fluid, particularly if the vehicle has drum brakes.

5. Inspect Master Cylinder

Look for any signs of leakage around the master cylinder.
If leaking, remove the master cylinder by disconnecting the brake lines and unbolting it from the brake booster.

6. Repair or Replace Affected Components

Replace any damaged brake lines or hoses using the appropriate size and type of replacement parts.
If calipers or wheel cylinders are leaking, replace them as necessary.
If the master cylinder is faulty, install a new one and bleed the brake system to remove air.
