Solution

1. Preparation

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

2. Inspect and Repair Leaks

Tools Required: Wrench set, brake line repair kit, brake cleaner
Inspect all brake lines, hoses, and connections for leaks.
If a leak is found, replace the damaged line or hose with a new one.
Clean any spilled brake fluid with brake cleaner to prevent damage to surrounding components.

3. Replace Brake Fluid

Tools Required: Brake fluid, funnel, turkey baster (optional)
Use a turkey baster to remove old brake fluid from the reservoir.
Fill the reservoir with the manufacturer-recommended brake fluid type (consult owner's manual).
Ensure that the fluid level is between the "MIN" and "MAX" markings on the reservoir.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing
Start at the wheel farthest from the master cylinder (usually the right rear).
Attach clear tubing to the bleeder valve and place the other end in a catch container.
Ask an assistant to pump the brake pedal several times, then hold it down.
Open the bleeder valve to release air and fluid, then close it before your assistant releases the pedal.
Repeat this process until no air bubbles are present, then move to the next wheel.
Check the fluid level in the reservoir frequently and top off as needed.
