What Are Brake Lines?
Brake lines are hoses that transfer brake fluid from a reservoir through a pump or modulator to a brake master cylinder to create hydraulic pressure to push the brake pads against the disc rotor or drum brake, slowing or stopping the vehicle. If the brake fluid becomes depleted or air enters the brake lines, the brake response can weaken and the brake lines will need to be bled or flushed. Hire a certified mechanic to perform this service, as special equipment is often required.
