Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and securely lift with jack stands.
Wear gloves and eye protection.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Remove the cap and check the fluid level against the minimum and maximum markers.
If low, add the recommended DOT fluid to the appropriate level.

3. Examine Brake Lines and Hoses

Visually inspect all brake lines and hoses for any signs of damage or leaks.
Use a flashlight to check hard-to-see areas.
If any leaks or damage are found, replace the affected brake lines or hoses.

4. Check Calipers and Wheel Cylinders

Remove the wheel to access the brake caliper.
Inspect the caliper for any signs of fluid leaking, especially around the piston seals.
If a leak is detected, replace the caliper.

5. Inspect Master Cylinder

Locate the master cylinder, usually found near the brake booster.
Check for any signs of fluid leaking around the seals or the reservoir.
If leaking, replace the master cylinder.

6. Test Braking System

After repairs, reassemble any removed components, ensuring all connections are tight.
Lower the vehicle and pump the brake pedal to build pressure.
Ensure the pedal feels firm and responsive before further testing.
