Hey I am trying to get my pistons our of my calipers of my 94 F2 with brake fluid but I cant seem to get brake fluid into my lines. I have checked the diaphram and it is working correctly it will pump fluid up to the the top of the lines, I did my best to keep any airbubles from getting between where the lines begin and where the brake fluid reservoir ends. Anyone have any advice on how I can get the brake fluid flowing into the lines? ps(I have tried plugging the ends of the lines and letting air out and then plugging it for the recoil but it did not seem to work as well as i thought it should.)

 

To bleed lines you need to loosen the bleeder screw on the caliper, squeeze the lever, then before you let the lever go, tighten the bleeder screw. Then once you let go of the lever, fluid will be drawn from the MC and you will repeat the whole process over and over until you get no air at all.

 

are you trying to remove the pistons or are you just trying to get the air bubbles out?

to make it easier, geta vacuum pump like the mity vac.

if you're trying to get the pistons out for a rebuild or whatever you need to use compress air.

 

Thanks for the advice, and ya I am just trying to remove the pistons right now... I do not have an air compressor though.

 

to remove the pistons, you gotta take both sides of the cailpers apart. then use compressor to blow air into the passage that connects both sides of the calipers and lets fluid through. plug up the open end (where caliper bolt goes in). hold one of the pistons, the other will pop out with avengeance. do the same for the other side. after 1 piston is out per caliper side, you'll need to block that passage with your hand or something.

fluid alone won't extend it far enough to get it all of them out.

 

Go to a mechanic place and see if they'll put an air hose on them. I'm sure they'll be kind enough not to charge you.
