Rear discs... proportioning valve
I know much has already been posted on this and I've read what I could find but still could use some help/clarification. Car is a 1990 IROC that had drums in back. Swapped rear end to a 9 inch Moser with disc brakes last year. Braking suffered. From what I've read it sounds like I need to change the proportioning valve or replace the spring. Not sure which exact valve I would need because I don't know anything about the calipers. Is this the one I need? http://www.flynbye.com/catalog/i172.html. 90-92 1LE/J65 valve. Or a different one? Is it worth just trying to replace the spring first? I think this is the one? https://www.grainger.com/product/GRA...s-Spring-1NCR5
Thanks very much in advance?

I'm trying to figure this out also. I changed the spring out for the 1NCR5 and still no rear brakes after bleeding them.

Don't know. The brake assembly on the Moser rear end is made by a company called The Right Stuff products. www.getdiscbrakes.com
