The Brake Line is a very important part of your vehicle's braking system. The brake line consists of tubing with two metal, hex-shaped fittings that has the essential role of carrying brake fluid to the brakes. Brake line replacement is imperative when an existing brake line becomes brittle, frayed, broken or has leaks. Timely replacement is needed sooner than later, in order to ensure the safe operation of your vehicle. Overextending the service life of the brake line can lead to serious risks in the operation of your vehicle.
