Shopping for Brake Line

Brake Line Shopping Info

What Is a Brake Line?

Your vehicle depends on the brake line to deliver the brake fluid from the master cylinder to the brake caliper pistons. It’s the part that helps power the hydraulic braking system of your car, allowing you to stop or slow down whenever you step on the brake pedal.

How Much Does a Brake Line Replacement Cost?

An aftermarket brake line costs around $5 to $210 for the part alone. Factors that can affect its price include material, kit or set inclusions, recommended use, product fit, and warranty. If you’re hiring a professional mechanic to replace your damaged brake line, you may have to spend an additional $100 to $200.

Where Are Brake Lines Located?
Where Are Brake Lines Located?The majority of brake lines are metal rather than rubber, which is only found at the wheels and rear axle. The tubes must hold over 2000 pounds of fluid pressure, which they transfer pressure from the master cylinder to the brake calipers or wheel cylinders. This hydraulic pressure causes the
