Master Cylinder Replacement - ZR-1 Net Registry Forums

Related to my Brakes Failed thread

My master cylinder went out and requires replacement. During this process I have decided to do a bet of a brake overhaul. I painted my calipers, bought new pads and discs, rebuilt master cylinder, brake hoses, and speed bleeders.

I bought the Cardone tool to reverse bleed the master cylinder. This should cut down the process of bleeding the master cylinder. There are 2 different processes depending on the type of MC. Would the Corvettes MC be considered a "step bore MC" or a "conventional MC"?

Should the replacement of the MC be pretty straight forward?

C4 masters are "conventional".

I did the reverse bleeding as well as the traditional bench bleeding. It seemed to pretty easy. Kind of a mess, but its on the car.

I put my car back together last night, only to find out that my master cylinder wasn't bad, it was actually one of the brake lines off of the master cylinder. I only found this out because I filled my brake reserviors and today they were low, so I filled them up again, and same thing happened. This is redic. I'm about to blow this car up. Not only did brake fluid leak everywhere, but it has eaten some of the paint on the little fiberglass panel where the battery goes.

Where can I find these brake lines?
