Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool if it has been running.

2. Check Brake Fluid Reservoir

Tools Required: None
Remove the cap from the brake fluid reservoir.
Inspect the fluid level; if it's low, note the possible leak source.
Wipe the reservoir cap and area clean before reattaching to avoid contamination.

3. Inspect Brake Lines and Hoses

Tools Required: Socket set
Visually inspect all brake lines and hoses for signs of leaks or damage.
Use a flashlight to check for cracks or rust.
If any lines are damaged, proceed to replace them.

4. Replace Damaged Brake Lines or Hoses

Tools Required: Wrench set, brake line flaring tool (if necessary)
Remove the damaged line by loosening the fittings with the wrench.
Install the new brake line or hose, ensuring proper routing and secure connections.
Tighten fittings to manufacturer specifications (usually around 15-25 ft-lbs).

5. Inspect and Replace Brake Calipers/Wheel Cylinders

Tools Required: Socket set, brake cleaner, new calipers/wheel cylinders
Remove the wheel to access the brake caliper or wheel cylinder.
Check for brake fluid leaks around the caliper or cylinder seals.
If leaking, remove the affected caliper or wheel cylinder and replace with a new one.
Bleed the brakes after installation to remove air from the system.

6. Check and Replace Master Cylinder (if necessary)

Tools Required: Wrench set, brake fluid, new master cylinder
Inspect the master cylinder for fluid leaks, particularly around the seals.
If leaking, disconnect brake lines and remove the master cylinder from the mounting.
Install the new master cylinder, reconnect the lines, and bleed the system.
