Need Help with brakes.... ***URGENT***

[Hektik]

OK here's my situation... Yesterday I did a tune-up on my car.. When changing the pads I found my driver side caliper had a ripped piston boot.. So I went ahead and got new calipers.. Calipers and pads mounted I went ahead to do the bleeding.. Here's where my problem is at.. My front driver side and rear passenger side bleed just fine.. But my front passenger and rear driver sides do not bleed out... Any and all suggestions will be appreciated... I'm starting to think it might be my MC or my proportioning valve...

changed out the MC but still no luck:doh: ... next step i guess is the dual proportioning valve...so here's my question....should i just pick up a model specific one or would i receive any benefits from getting a 40/40...:goodjob:..

What kind of car is this? And how are u bleeding the brakes?

[Hektik]

95 civic sedan.....i bought a one man bleeding kit.. open valve 1/4 turn, plug hose on valve then to tube, pump brakes fill reservoir.. passenger rear and driver front bleed fine and all new fluid is running through it now.. passenger front and driver rear will not bleed ever with the valve open no fluid/air comes out...

i should be picking up the dual proportioning valve from the stealership today... hope fully this will fix it.. if not them im thinking it might be the line that runs from the Mc to the proportioning valve..

the proportioning valve fixed the bleeding issue... but now the brakes are feeling spongy im hoping its because the pads and calipers are new and still need a bit to break in...
