Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear protective gloves and eyewear.

2. Identify the Leak Source

Sub-step 1: Visually inspect the brake lines, hoses, and connections for signs of fluid leakage.
Sub-step 2: Check the brake calipers and wheel cylinders for fluid accumulation.
Sub-step 3: Examine the master cylinder for any leaks around the seals.

3. Replace Damaged Components

Sub-step 1: If a brake line or hose is damaged, use a wrench to disconnect it from the fittings and replace it with a new line or hose.
Sub-step 2: If the leak is from the caliper or wheel cylinder, remove the affected part:
- For a caliper, remove the caliper bolts and slide it off the rotor.
- For a wheel cylinder, remove the brake drum and unbolt the cylinder.
Sub-step 3: Install the new part, ensuring proper torque specifications are followed (refer to the vehicle manual for specific values).

4. Refill Brake Fluid

Sub-step 1: Fill the brake fluid reservoir with the recommended brake fluid type (DOT 3 or DOT 4).
Sub-step 2: Bleed the brake system to remove any air bubbles:
- Start from the furthest wheel from the master cylinder and work your way closer.
- Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve.

5. Final Inspection

Sub-step 1: Check for any leaks around the repaired areas.
Sub-step 2: Test the brake pedal feel by pressing it several times to ensure it is firm.
