1997 ford taurus: a leak in the brake line and I

This answer was rated:

my 1997 ford taurus has a leak in the brake line and I have the replacement line, but I don't know how to install it.


Which section of line is it?

Rear drum or disc brakes? and how long is the new brake line?
Customer: replied 10 years ago.
honestly i have no idea, im a 19 year old girl at school and my dad is the one that fixes all of this lol but the new brake line is about a foot long, but i feel like they are disc brakes

Thats fine,,,i proud of you to take on the questioning!

Do you know if the line is steel or rubber? this will tell me if they are drum or disc.

Customer: replied 10 years ago.
its rubber

Ok,,thank you,

That means it has rear disc.brakes, just like you thought :-)

Any time the lines are removed or disconnected, extreme cleanliness must be observed. Clean all joints and connections before disassembly (use a stiff bristle brush and clean brake fluid); be sure to plug the lines and ports as soon as they are opened. New lines and hoses should be flushed clean with brake fluid before installation to remove any contamination.


See Figures 1, 2, 3 and 4

  1. Disconnect the negative battery cable.

  2. Raise and safely support the vehicle on jackstands.

  3. Remove any wheel and tire assemblies necessary for access to the particular line you are removing.

  4. Thoroughly clean the surrounding area at the joints to be disconnected.

  1. Disconnect the other end of the line or hose, moving the drain pan if necessary. Always use a back-up wrench to avoid damaging the fitting.

  2. Disconnect any retaining clips or brackets holding the line and remove the line from the vehicle.

If the brake system is to remain open for more time than it takes to swap lines, tape or plug each remaining clip and port to keep contaminants out and fluid in.

To install:

  1. Install the new line or hose, starting with the end farthest from the master cylinder. Connect the other end, then confirm that both fittings are correctly threaded and turn smoothly using finger pressure. Make sure the new line will not rub against any other part. Brake lines must be at least 1/2 in. (13mm) from the steering column and other moving parts. Any protective shielding or insulators must be reinstalled in the original location.

NOTE: Make sure the hose is NOT kinked or touching any part of the frame or suspension Using two wrenches as before, tighten each fitting.

  1. Install any retaining clips or brackets on the lines.

  2. If removed, install the wheel and tire assemblies, then carefully lower the vehicle to the ground.

  3. Refill the brake master cylinder reservoir with clean, fresh brake fluid, meeting DOT 3 specifications. Properly bleed the brake system.

  4. Connect the negative battery cable.
