i have an 89 crx hf. i am about to do a rear disk conversion this is what i have: a complete 91 crx si rear disc setup, a 91 integra da (non-abs) master cylinder (15/16), a 40/40 prop valve, and stainless steel brake lines. my question is: do i need to change the 89 crx hf brake booster?

 

from the research i have done i assume i dont. so if anyone has any information saying i should replace the brake booster, please tell me

 

i dont think so... my friend just did his and he didnt..

 

thanks
