Solution

1. Preparation

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

2. Inspect and Replace Brake Fluid Reservoir

Sub-steps:
1. Remove any plastic covers blocking access to the brake fluid reservoir.
2. Inspect the reservoir for cracks or leaks. If damaged, remove it by unscrewing the retaining bolts.
3. Replace it with a new brake fluid reservoir and secure it in place.

3. Check and Repair Brake Lines

Sub-steps:
1. Visually inspect all brake lines from the master cylinder to the wheels.
2. Use a wrench to loosen the fittings and check for leaks.
3. If leaks are found, replace the affected sections of the brake line using appropriate brake line tubing and fittings.

4. Inspect and Replace Brake Calipers and Wheel Cylinders

Sub-steps:
1. Remove the wheels to access the brake calipers and wheel cylinders.
2. Look for any signs of brake fluid leaking around the calipers or wheel cylinders.
3. If leaks are present, remove the old caliper or cylinder and replace it with a new one. Ensure to bleed the brakes afterward.

5. Check and Replace Master Cylinder

Sub-steps:
1. Locate the master cylinder and inspect it for leaks.
2. If leaking, disconnect brake lines and remove the master cylinder from its mounting.
3. Install a new master cylinder and reconnect the brake lines. Bleed the brake system to remove air.

6. Refill and Bleed Brake System

Sub-steps:
1. Use high-quality brake fluid as specified in the vehicle manual.
2. Fill the brake fluid reservoir to the recommended level.
3. Bleed the brake system to eliminate any air pockets, ensuring proper brake function.
