How complicated is a brake line replacement?

Have you ever wondered what is involved with replacing brake lines on a vehicle?

Our Southwestern Ontario Canadian winters mean snow and to combat that issue salt and deicer are applied to all major roads and highways. This inevitably means one thing for the undercarriage components of all vehicles that travel our roads... They will rust.

Brake lines are usually exposed to the elements at some point in the undercarriage of the vehicle. Some modern vehicle manufacturers have gone to a coated brake lines to try to prevent this issue from happening, but over time exposure will still cause corrosion and eventual failure of the component.

There are many components in the hydraulic system of your vehicle's brakes. The brake master cylinder and brake lines are what hold the hydraulic fluid and allow transfer to the brake calipers or in the case of drum brakes, the rear wheel cylinders.

Typical cost of brake line replacement is 2 to 5 hours labour depending how complicated the system is and how much of the brake lines are being replaced. In the case of some vehicles a scanner is required to operate the ABS controller to properly "bleed" the brake system of air.

some manufacturers offer premade brake lines through the dealer that save time (in most cases)
on installation. The trade-off of course is the cost of the lines themselves tend to be much higher in price than the shop manufacturing the lines from scratch.

Other vehicles may require a reset of the brake system again with a programming scanner depending on what components of the hydraulic brake system are being addressed with the brake line replacement.
