jzd14 Posted July 6, 2002 Share Posted July 6, 2002 i have a '73 240z and i put toyota calipers on the front along with stainless brake lines from MSA the problem is i can't get any fluid to come out of the bleeder...i can't even get air to come out can the stock master cylinder not provide enough push to get the fluid out through the bleeder in these new calipers? any insight at all is appreciated thx Quote Link to comment Share on other sites More sharing options...
Guest greimann Posted July 6, 2002 Share Posted July 6, 2002 You might need to bleed the master cylinder first. There should be little bleeder fittings on the side (at least they are on my ZX). Quote Link to comment Share on other sites More sharing options...
jzd14 Posted July 6, 2002 Author Share Posted July 6, 2002 yeah...i thought that might have been the problem too...but it didn't help any other thoughts? Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted July 6, 2002 Share Posted July 6, 2002 Check all your connections, esp where the line connects to the caliper. Are the little copper washers on there? If not air will get in and you'll never get any fluid out. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted July 6, 2002 Share Posted July 6, 2002 Are the calipers installed so the bleed screws are up? Does the master cylinder bleed, does it have pressure? Quote Link to comment Share on other sites More sharing options...
jzd14 Posted July 6, 2002 Author Share Posted July 6, 2002 actually...that was the first problem i had when putting the brake lines on the toyota calipers...the brake line wasn't sealing to the caliper...brake fluid kept leaking out when i'd stroke the pedal i had to file down the caliper a little where the washer seals against it and then get new washers to put it back together with all the copper washers are on there now though and everything is tightened well i know brake fluid is getting into the caliper because when i pump the brake pedal, the pistons in the caliper move a little i just can't get anything to come out of the bleeder any other thoughts?

jzd14 Posted July 6, 2002 Author Share Posted July 6, 2002 the bleeder screws are on the top of the calipers...and the master cylinder bled fine...i'm not quite sure what u mean by pressure though...pressure where?...there is some pressure in the brake pedal but no where near enough to stop the car...and the pedal pressure could just be because i bled the back brakes first (they worked fine) Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted July 6, 2002 Share Posted July 6, 2002 I meant pressure at the master cylinder, does it squirt when you open the bleeder valve? Bleed it with a small tube attached to the bleeder valve and the other end in a bottle with a little brake fluid in the bottom to cover the tube. pump the pedal several times, be careful not let the master cylinder get low, then do the same with the right caliper first, then do the left.If all else fails undo a line from a caliper and see if you get fluid from the open line. Are the tyota calipers new, rebuilt or what? Quote Link to comment Share on other sites More sharing options...
jzd14 Posted July 6, 2002 Author Share Posted July 6, 2002 the master cylinder bled fine...and i know fluid is getting into the caliper because stroking the brake pedal causes the pistons to move a little bit...nothing is coming out of the bleeder though Quote Link to comment Share on other sites More sharing options...
CruxGNZ Posted July 6, 2002 Share Posted July 6, 2002 Maybe... when you were filing(sp?) that metal away, some of it got inside the caliper and is now blocking the bleeder. Just throwing some ideas out here for you. Did you take the bleeder out completley and see what happens? It really sounds like you are just pushing air through the lines and no fluid yet. Just out of curiosity, could you tell us the process that you use to bleed the brakes? !M! Quote Link to comment Share on other sites More sharing options...
blueovalz Posted July 6, 2002 Share Posted July 6, 2002 Many times on salvage parts the small holes in the bleed screw will become corroded over to the point that they get plugged up solid (damn brake fluid loves water). remove them, poke a safety pin or something similar into it, blow it out with air, and you should be fine.

jzd14 Posted July 9, 2002 Author Share Posted July 9, 2002 hey guys...thx for the help so far this stupid thing is still giving me problems though i think what i'm going to do is take the caliper off and see if i can shoot some air through it with my compressor...to make sure there's a passage through the caliper if no air comes out the bleeder, then i guess i'll just go to napa and get another one thx again for the ideas though Quote Link to comment Share on other sites More sharing options...
