Replace master cylinder and brake lines
Well since my brake mastercylinder on my 96 LT4 is leaking and needs replaced I have decided to replace the rubber brake lines with SS lines and flush and replace the brake fluid. Having never done this before I have some questions. I already have the new SS lines and am going to buy a new(not rebuilt) MC. I may also install speed bleeders as that seems like the easiest way to bleed the system. Now for the questions. Since I will be bleeding the whole system is it necessary to bench bleed the new MC or just install and fill and then bleed ? How hard is it to replace the brake lines and is there a number to torque them down to so they do not leak ? Any tips would be appreciated. Thanks in advance. Guy

When I replaced the master cylinder on my 86' I didn;t have a vise, so I bench bled it on the car. I installed the master cylinder, but left the lines disconnected, and installed the little return hoses and bleed the master cylinder that way. After that was done I reattached the lines. You may not have to do that, but I know that method worked for me.

In regards to the stainless lines if you go with goodridge, I remember them coming with torque specs for everything. If not go with what is in the manual. I have done stainless lines of a lot of cars, never had one leak.
Every car we have put speed bleeders on we encounter problems down the line. Are they easy at the times, yes. Will I ever use them again, no. Easiest way to bleed is with a pressure tank on the master cylinder. I still use the the two many method with a vac on the bleed valve and a lot of leg pumping. It always works.
