Diagnostic Steps

2
Check for any visible leaks in the brake lines and hoses.
3
Inspect the brake calipers and wheel cylinders for signs of leakage.
4

Solution

1. Preparation

Tools Required:
- Brake fluid
- Clean rags
- Wrench set
- Brake line flare tool (if needed)
Ensure the vehicle is parked on a flat surface and the engine is off. Allow the brakes to cool if they have been used recently.

2. Inspect Brake Components

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; if it’s low, wipe the reservoir with a clean rag and inspect for leaks.
3. Use a flashlight to examine the brake lines from the master cylinder to the calipers.
4. Look for any signs of wetness or corrosion, indicating a leak.
5. Inspect the calipers for fluid around the seals and check the wheel cylinders for seepage.

3. Address Any Identified Leaks

Sub-steps:
1. If a leak is found in the brake lines, use a wrench to loosen the affected area and replace with a new section of brake line as needed.
2. For caliper leaks, detach the caliper, replace the seal, and reattach using a torque wrench set to the manufacturer’s specifications (usually around 25-35 ft-lbs).
3. If the master cylinder is leaking, remove it by disconnecting the brake lines and unbolting it from the brake booster, then replace it with a new unit.

4. Refill and Bleed the Brake System

Sub-steps:
1. Refill the brake fluid reservoir with the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
2. Bleed the brakes to remove any air from the system:
  - Start at the furthest wheel from the master cylinder and work towards the closest.
  - Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve on each caliper.
