Solution

1. Preparation

Gather tools and materials: brake fluid, wrench set, socket set, brake line wrench, and cleaning cloths.
Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.

2. Inspect and Repair Leaks

Sub-step 1: Visually inspect all brake lines, hoses, and fittings for signs of fluid leaks. Pay attention to the master cylinder and brake calipers.
Sub-step 2: If leaks are found, replace the damaged brake line or hose. Use a brake line wrench to avoid rounding off fittings.
Tools Required: Brake line wrench, socket set.

3. Replace Brake Fluid

Sub-step 1: Open the brake fluid reservoir cap and remove any debris.
Sub-step 2: Use a turkey baster to remove old brake fluid from the reservoir.
Sub-step 3: Fill the reservoir with new brake fluid that meets DOT 3 or DOT 4 specifications.
Sub-step 4: Replace the reservoir cap securely.
Tools Required: Turkey baster, funnel.

4. Bleed the Brakes (if necessary)

Sub-step 1: Start at the wheel farthest from the master cylinder (usually the right rear).
Sub-step 2: Attach a clear tube to the bleeder valve and submerge the other end in a container with brake fluid.
Sub-step 3: Have an assistant pump the brake pedal several times, then hold it down.
Sub-step 4: Open the bleeder valve to release air and fluid, then close it before the pedal is released.
Sub-step 5: Repeat for each wheel in the correct order (right rear, left rear, right front, left front).
Tools Required: Brake bleeder kit, wrench for bleeder valves.
