Hey guys, my brake hose that connects to the abs module from the master cyclinder is leaking. GM canada wants 125 for the hose. it is a hardline that turns into a braided steel line then connects back to a hardline. Has anyone changed this line to full hardline?

You should be able to replace it with a hard line, just be sure to coil up some of the line to act as a strain relief between the two. Coils should be about the diameter of a soda can and there should be 3-4 of them to allow for adequate displacement between the two.

crap, all i did was cut the flex line out, bought some 1/4" hardline, 4 fittings, and 2 joiners. I flared each end of new hardline, the line i cut that connects to the master cyclinder, and the line that goes to the abs modulator. I'll have to take a picture of my work. The length of the new line is the exact length of the flex line and shape. Here is the line that i was talking about.
I will have to redo it and add a few coils.

EDIT: i bleed the brakes, but i still have the soft pedal/all the way to the floor syndrome. I pump the pedal with the engine off and about 2 pumps it stiffens up a bit, its not rock hard and the pedal still has about 1-2cm of play. As Im applying firm pressure, i started the truck and the pedal went all the way to the floor.... does this mean my mc is shot??
