Vette y2k rims and brake upgrade
 

Hello. I have been out of the loop for a while and am trying to find out what i need to finish my brake swap and get it going. I finaly got my rims.. y2k 18 rear 17 front. I have a complete set of front vette 13.5 rotors and calipers and a rear set of ls1 brake including the backing plate.

My questions.
I have 2 valves one was from a drum and one was a disc how can i tell them apart?

I have EB miller caliper brackets, I know I also need the special hub, Is there anything else?

Will I need spacers in the rear to match the front width after the new spindles are on? They move the wheel out farther then stock right?

Thanks

SO I was reading back through some PM messages from a few years ago.

My fronts are C4 brakes. I have the brackets from EB I think the only thing I need are the 1le hub setups. sound right .. anyone?

I also found out I might not need to run spacers on the front, only the rear.


still unclear how to tell which proportioning valve is for disc brakes.

The two look the same on the outside and there're no part numbers on them that might distinguish them. Sounds like you require either a 1LE valve or an adjustable.

yea I'm not sure if it will even work if it is a disc p valve. One is from a 89 GTA and the other is just a standard 92 drum valve.

Ok... I found out a little more.

I have a j50 and j65 master and prop valve... one of both setups.

Sould I use the j50 master with the j65 disc rear prop valve?
I read that the pedal feel is better with a j50 master and a disc prop valve.

That's the set-up I'm using to good effect. Perhaps the following link, toward the bottom, will provide you with brake info that will provide interesting to your project:
