Hi, I am completely new to this forum and this is my first post. I have an 89 CRX and am about to undergo a rear disc conversion sourced from a 93 integra. I am looking for the correct proportioning valve, I have been told to use both the 2040 and 4040 and am looking for clarification. I am running stock discs up front and would like to know exactly which proportioning valve to purchase. I think that the user Tyson may have a few 4040's for sale but due to my new status on this forum I am unfortunately unable to contact him via IM.

Also is it completely out of the question to use my stock valve?


Thanks
Ryan.

 

its difficult to be 100% sure which prop valve is to be used for all combinations, so i recommend trying to replicate the complete braking system of another chassis as much as possible.

however, DX sized front brakes and rear calipers matches no other OEM system.

yet, many ppl have still bought 4040 prop valves from me and have not had issues. i dont know what each of them used for their brake system. i have no control or record of that. other than ive not received any negative feedback from unsatisfied buyers.

i still have 3 4040 prop valves available.

 

new here but have problem, need 1990 Honda crx proporting valve,, do you have one??

 

integra's use 4040, go with that and you will be fine.
