Big$exyBlazer · 11-25-2006, 06:08 PM

what do you mean?

bigyellowjimmy · 11-25-2006, 06:52 PM

do you have a vac bleeder? You prolly have air that pumping the pedal isnt pushing out

Big$exyBlazer · 11-25-2006, 07:01 PM

i just unhooked my flexible brake line from my stock line and no fluid is comin out, what to do now?

bigyellowjimmy · 11-25-2006, 07:25 PM

do you have a vac bleeder??

Big$exyBlazer · 11-25-2006, 07:34 PM

No i dont where can i get one? do you think this is what i need?

suburban N progress · 11-25-2006, 09:01 PM

Local auto parts store has a vac bleeder.. also if the factory proportional valve tripped I have had good luck with my buddy pumping the breaks while i tap the valve and it releases the lock out to the rear line and bam you got fluid going back there..takes a little bit but it worked for me 3 times.

bigyellowjimmy · 11-26-2006, 08:00 AM

like suburban said, you can pick one up at any parts store for $30-40, you can bleed your brakes by creating a vacuum and forcing the fluid past the air lock. If you put a vac on it and it doesnt suck the fluid down in the MC you'll need to investigate the PV having an air lock like has been mentioned.

good luck

ont ht eend of the prop valve is a small black rubber cap, push it and pump the pedal, push it and pump the pedal, it will flow, just be paiteint and keep pumping

What do you guys do about the proportioning valve when swapping to disc brakes on a 14 bolt? Do you remove the check valve or is it fine to leave the proportioning valve alone? Thanks, Mike

suburban N progress · 12-02-2006, 03:01 PM

I left mine alone and never had any problems..never once did i lock my rear on wet roads and bring the ass around..worked great..but that was me though..i dont know if anyone else had same success

trkklr77 · 12-02-2006, 06:34 PM

i left the prop on and i can slide my rear if i want to in the wet, but the work great all the time, if you really stomp on them theyll lock but i havent had them un-expectedly lock in a emergency stop.
