Okay so after a year passed by from my car being the body shop I'm in the process of putting my Integra together.I put all my brakes on and it only pumps out fluid from two wheels (driver front, passenger rear)
History: New RS master cylinder, all new stainless lines, 40/40 prop. valve

 

likely a problem with the prop valve. pull the lines and have someone pump, check fluid output directly

 

Okay no fluid pumped out when I removed the lines from the prop valve...so I guess I'm going to buy a new one

 

is fluid coming from the lines BEFORE the prop? if so, it's the prop, if not.. it's the MC

 

I don't know I'm assuming it is because it pumps fluid to two wheels only...but ill check if it pumps fluid out of those two lines before it reaches the prop valve

 

did u bench bleed the mc?

 

1 yr ago yeah :p

 

Driver front and passenger rear involve the REAR half of the master cylinder. That circuit seems to have been bled of air.

I think you've just got a lot of air still left in the other circuit. Keep bleeding the driver's rear and passenger front.

Are you using the pedal-pump method or a Mity-Vac?

 

mity vac is goood

 

The pedal pump...I've been pumping for days...when I unpluged the lines from the mc prop. valve only the rear line was pumping out fluid, so Ima bench bleed it...but could it also be the prop. valve?

 

I changed out mine had similar problem.

 

try bleeding at the MC-in vehicle
it's the highest point of the system, so air gets trapped there easily

 

Bump since i dont feel like making a new thread


i recently Deleted my ABS bought new hardlines and a master cylinder and SS brake lines i bench bled the master before i put it on and.. now im only getting fluid out of my Right rear caliper...my 40/40 prop valve was working fine before too

still too much air in the system? somethings broken? any ideas?

 

usually if i replace calipers or lines, i like to gravity bleed. that is, crack the bleeders and let the air purge on it's own.
also, if the master cylinder is replaced, you want to bleed there, since it's high up in the system and air is easily trapped there
