I have a set of 90 si trailing arms with disk breaks. I am gonna swap out the 90 crx drum trailing arms. Will I need to change the prop valve or can I run what I have.
Thanks for any info

How To: Rear Disc Brake Conversion

OK, since there is no "How to" for the rear disc brake conversion, here is a little write up of how I did mine. Moderators do your thing if it qualifies as a "how to" 1. Buy your disc set up (any 90-2001 Integra, 90-91 CRX Si, 92-2000 Civic or 93-97 Del Sol with rear discs will work) 2. Since...

thanks Baker....got all the new bushing and rebuild parts to have a new trailing arm. Just read so much about the prop valve but everyone has to put their own spin on it and didn't really talk to my issue, hadn't seen the ref. write up.

You won't need to change the prop valve but it would help the correct braking ratio. I actually have an si prop valve for sale if you're interested.

this is a common misconception. in short, no. here's why:
the drum-eqipped CRX (or any honda for that matter) has integral valves that send brake fluid JUST to the rear brakes first. this helps fill the gap between the drum shoes and drums (they have more clearance than disc brakes and are not as immediate). when the resistance is felt, then fluid can be let to the front and rear. when you convert to rear discs, that resistance is felt immediatly and the rest of the pedal stroke will behave the same. most cars send pressure to the rear drums first as it reduces nose dive (compared to say a car from the 1930s or something)
