Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and set the parking brake.
Use jack stands if the vehicle needs to be lifted for inspection.
Wear gloves and safety goggles for protection.

2. Inspect the Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the reservoir for cracks or damage.
If damaged, remove and replace with a new reservoir.

3. Check Brake Lines

Follow the brake lines from the master cylinder to the calipers.
Look for any signs of fluid leakage or damage.
If leaks are found, replace the affected brake line sections using a flare wrench.

4. Examine Brake Calipers and Wheel Cylinders

Inspect each brake caliper for signs of brake fluid leakage.
Clean any visible dirt around the caliper area to accurately assess leaks.
If leaking, replace the caliper or the o-rings as needed.

5. Inspect the Master Cylinder

Remove the master cylinder from its mounting if leaks are suspected.
Check the mounting surface for corrosion or damage.
If leaking, replace the master cylinder with a new unit, ensuring proper torque specifications for bolts when reinstalling.

6. Test the Brake System

After repairs, refill the brake fluid reservoir with the recommended brake fluid type.
Bleed the brake system to remove any air bubbles, following the manufacturer’s specific bleeding procedure.
