Cable Posted August 13, 2010 Share Posted August 13, 2010 Hey guys. I got a Kragen gift card for my birthday last month and decided to spend it on some Toyota 4x4 calipers for my S30. I got the version to use with the stock (non-vented) rotors. Anyway, I installed them today along with some new braided stainless steel brakelines. Added new sync DOT 3 fluid and began the bleeding process. I had a friend pump the pedal while I used a length of tubing over the bleeder screw into a small jar with some brake fluid to keep the air out. After while switching side to side no more air bubbles. However I still don't have any piston movement on either caliper. None at all. The pistons haven't even moved enough to take up the space between the pistons, pads, and rotors. I am getting fluid to the bleeders as I had to refill the master cylinder a few times. So now I am at a loss. I thought it might be the master cylinder, but it was replaced 9 months ago and was working fine yesterday with the stock calipers. Ideas guys? Thanks!!

Cable Posted August 13, 2010 Author Share Posted August 13, 2010 Yup. The left side (driver) side caliper is even has a big "L" cast into it. Quote Link to comment Share on other sites More sharing options...
FlatBlack Posted August 26, 2010 Share Posted August 26, 2010 (edited) Did you have the bleeder screws open the entire time while pumping the air out? The same thing happened to my virgin S12+8s before I rebuilt them, but that's because the pistons were frozen.

Daphur280 Posted August 26, 2010 Share Posted August 26, 2010 Bleeders pointing up? Are the bleeders suppose to be towards the top of the calipers when mounted or towards the bottom? Mine were not stamped with "L" or "R", and I assumed the bleeders were positioned on the calipers by the purpose in law of gravity, so that they would be bled from the lowest point... In any case I'm having the same issue, my calipers or the rest of the braking system will not bleed! Quote Link to comment Share on other sites More sharing options...

Air is lighter than brake fluid... so it goes to the top. Quote Link to comment Share on other sites More sharing options...
Daphur280 Posted August 26, 2010 Share Posted August 26, 2010 Good point, forgot my physics... will remount and try again... Quote Link to comment Share on other sites More sharing options...
Daphur280 Posted September 1, 2010 Share Posted September 1, 2010 did air get into the master cylinder when you removed the calipers (failure to pinching brake lines is something I did during mine)? Quote Link to comment Share on other sites More sharing options...
Cable Posted September 1, 2010 Author Share Posted September 1, 2010 I ended up having to have them power bled and they now work just fine. Quote Link to comment Share on other sites More sharing options...
