Rex,

I have been running my original master cylinder (with the residual valve removed and rebuilt at the same time) since 2005 with the disc brakes. And prior to that with the drum brakes of course.

I have a dual master cylinder waiting in the wings, but so far have not needed it. I built it at the same time I built the dual for wmf62, with the MOPAR modified version (bolts directly in place of the original, and does not require the long tube that the aftermarket version has).

I know of several C1's with the front disc brakes, running the original master cylinder with zero issues (or they changed them out for a dual sometime later).

I ran my original M/C with 4piston front calipers and rear drums for 35 years with no problems. then, just to prove that the dual M/C could be used with a fender mounted FI aircleaner we changed to the dual M/C

Default Master cylinder

I didn't want to go through the hassle of removing the master cylinder, so I just removed the end cap and removed the residual valve. I bled the master cylinder and was good to go. Some will say I should have rebuilt the MC while I was at it but I'm from the old school. If it ain't broke, don't screw with it.

I like having the dual master cylinder. Just makes me feel safer with it.

Yesterday, my dual master disc brakes were very useful. A person pulled right out in front of me while I was going 40 MPH. I had to slam on the brakes in order to miss him. He made a left turn right across traffic and failed to see me at all in the far left lane. I might have flat spotted a tire because my corvette slid to a stop. Luckily, the car behind me was well far back enough not to slam into me. I did he him stop and was shocked too.

The sad part was the guy did not acknowledge he did anything wrong and kept eating his dinner like it was not a big deal.

I knew it was close because I was shaking from nerves afterwards.

Be careful out there!

yes and fit fine. I can take a picture for you. It came with the pin and clevis.

The only thing was I had to shim the extension to make it clear the hood.

I've been considering at the kit from POL. There is also a seller on Ebay offering basically the same kit with readily available rotors and calipers. For those of you who have used one of these kits, how much does it move the front wheels out?

It moved the wheels out about 1/2". I'm very pleased with the POL system. They are offering the adapters, bearings, and hardware for a very low price. They tell you what rotor and caliper to get. If you do it that way, you'll save quite a bit of money.

1/2" per side, or total?

Default per Side

Per side. It really is less than that but it has no effect as I can see. With the roller bearings that come with the kit, it seems to make everything tighter.

Iíll just say that my 61 was covertwd to disc on the front using 73 Camaro parts. They worked wonderfully and not big $$$ at all.
