ok we have replaced ( calipers,brakes,bled them,booster,) still made no big difference they still lock up ( at first they didnt lock up until i drove the car for 20 minutes but now they are locked up ) my next replacement would have to be the dual proportioning valve anyone know if i should ??? would the booster being adjusted make that much of a difference if it was a little bit off??? any tips would be helpful for this 90 CRX DX

 

yep, i've heard of this happening with incorrect prop valves

 

do you know what other type of car uses the same type of proportioning valve or any i can use on this crx . auto zone says nobody sells em and i had to go to a junkyard or dealer

 

u bought a new booster? if so ur suppose to adjust it to spec before u can install it..and adjust the push rod shaft

 

we wuz supposed to adjust the booster when it wasnt installed?????

 

that must be it... dammn

 

yes ..if u dont then that cuase the brakes to lock up. it happen to me 1 time until i adjust the shaft to close spec

 

or try adjust the shaft little bit lower and put no pressure on the booster and the master cylinder at all
