kosmic Posted July 13, 2008 Share Posted July 13, 2008 Had a quick search thorugh but couldnt find any decisive info. Ive read contradicatory info on bleeding the brakes on the Supra. I know the order is NSR,OSR,NSF,OSF but when actually bleeding the brakes, is the pedal pumped several times while the bleed nipple is open OR is the the pedal pumped several times while its closed and then held down while the bleed nipple is open and closed to release air. I dont want to screw anything up while doing this. So far ive been told to open bleed nipple, pump pedal several times slowly, Hold down and then close nipple?

Guest daz 6576 Posted July 13, 2008 Share Posted July 13, 2008 you need 2 people to do it at home. first keep your foot on the brake not too hard and get your mate to open the nipple and push the brake as far as it will go and keep it there until your mate has closed the nipple. then release your foot. do this in the right order then repeat the process again and make sure you top up your brake fluid reservoir. when you do it make sure the lid is off the reservoir until your finished Quote Link to comment Share on other sites More sharing options...
kosmic Posted July 13, 2008 Author Share Posted July 13, 2008 ok, does the pedal need to be pumped slowly while the nipple is open? or just pushed once through to the bottom and then closed? Quote Link to comment Share on other sites More sharing options...

kosmic Posted July 13, 2008 Author Share Posted July 13, 2008 See service manual here http://www.turbosupras.com/pdfs/JZA80%20TSRM/BR.pdf A bit confusing Nic as it doesnt mention priming the ABS system and also says when the fluid stops slowing then clsoe the valve Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted July 13, 2008 Share Posted July 13, 2008 Mate in car, foot on pedal, mate on bleed nipple with spanner and tube. Nipple guy opens nipple and tell pedal guy to push the pedal down. When pedal reaches carpet nipple guy shuts it off. Do not release pedal with nipple open cos you'll suck air/oil back into the system. Pedal guy releases pedal. Repeat until air free fluid is observed As above keep a healthy amount of fluid in the res or else youll pump air into the ABS system and you DONT want that!

Fantastic thank you, do you leave the ignition on to prime the ABS system? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted July 13, 2008 Share Posted July 13, 2008 The abs system shouldnt be affected if youre just bleeding the brakes. I take it you just changed your calipers or is it a precautionary bleed? if you get air in the ABS pump its a whole world of hurt mate. You'll need to pressure bleed and allsorts Quote Link to comment Share on other sites More sharing options...
