はじめに

Whether it is because of corrosion, rust, rounded off nuts, or damage from road debris there may be times when you need to replace the hard lines in your brake system.

In this case of the car used to create this guide they needed to be replaced because they had corroded to the soft rubber hoses to the point where the nuts on the hard lines rounded off during rubber hose removal.

Please note that when working with brake fluid that it is extremely corrosive to paint. If it gets any painted part on your vehicle be sure to rinse it thoroughly.

As you proceed through this guide be sure to collect any fluids in a suitable drip pan and also to dispose of old fluids properly.

Before beginning to remove the hard brake lines you'll need to drain the fluid from your rear caliper(s). You only need to drain the fluid from the side you're working on; if you're doing both lines, drain both. To drain them loosen the bleed screw and let the fluid drip in to a pan.

Find the brake line distributor at the rear of the car where the two hard lines split off to each wheel. It is just up behind the driver's side axle.

Repeat with the passenger side line. Loosen it from the distributor.
  • Repeat with the passenger side line. Loosen it from the distributor.

  • Note that this line may be routed through a bracket that holds both the hard brake line and the hard fuel line from the fuel tank in place with a rubber buffer. This is located directly up from and behind the rear differential.

  • If you find this on your car, loosen the 10mm bolt on the bracket. You do not need to fully remove the bracket, just loosen it enough that it releases the brake line. It can then be pulled out of the car.

Clean all the end connections of the hard lines, at the distributor and at the brackets for the soft rubber hose connection, with brake cleaner to remove any dirt. You do not want to introduce dirt in to your brake system. Let the brake cleaner dry. You can then begin reconnecting the soft rubber hoses, and can connect the hard lines to the distributor. Before driving your car you will need to bleed the system to remove the air that has been introduced. Never drive your car after doing work on the brake lines without first bleeding it properly. See the brake flush/bleeding guide for help with  this.
