a98pmalcolm Posted March 23, 2011 Share Posted March 23, 2011 Got my new caliper today, well re manufactured and i was considering changing it myself as im not to shabby with repairs ect.. But i have never changed a caliper before. How difficault is it on the supra's? I suspect not much different to other cars..

supra steveo Posted March 23, 2011 Share Posted March 23, 2011 2 bolts, 17mm iirc Quote Link to comment Share on other sites More sharing options...
monsween Posted March 23, 2011 Share Posted March 23, 2011 Thats it, just unbolt them. Make sure you have a brake pipe spanner for taking the pipe off. Without it you can round the nut. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted March 23, 2011 Share Posted March 23, 2011 As above, its easy, pair of 14mm bolts, just make sure you bleed it properly Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 23, 2011 Share Posted March 23, 2011 Two 14 mm head size bolts hold the calipers to the sliding pins. A 14 mm head size banjo bolt holds the fluid pipe union to the back of the calipers. A 10 mm head size bleed nipple is used to bleed the calipers. Dozens of J-Spec calipers are scrapped because people over tighten the bleed nipple and split the caliper casting itself. They merely need nipping up!!!! If you make sure the caliper piston is pushed fully into the casting before fitting it will bleed easier and faster and waste less fluid.

a98pmalcolm Posted March 23, 2011 Author Share Posted March 23, 2011 Ok thanks for the tips guy i have bleed kit... DOT4 fluid i assume and to bleed the new caliper do the usal poor fluid in - undo nipple - pump brake - do up nipple - poor fluid in - undo nipple - pump brake - do up nipple till all air bubbles have gone?

a98pmalcolm Posted March 23, 2011 Author Share Posted March 23, 2011 haha ok thanks chris And do we use DOT4? Quote Link to comment Share on other sites More sharing options...
supra steveo Posted March 24, 2011 Share Posted March 24, 2011 i replaced with 5.1 thats the high performance stuff Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 24, 2011 Share Posted March 24, 2011 Most true race fluids are DOT 3 or DOT 4. The DOT number is mainly based on water absorption over time. Race fluid gets changed regularly, so water absorption is pretty much irrelevant. they are only interested in dry boiling point. For example, Castrol SRF is an F1 level, top end race fluid, that's VERY expensive, yet is only rated DOT 3 / DOT 4 as it has poor ability not absorbing atmospheric moisture over time, but has a VERY high dry (uncontaminated fluid) boiling point.

a98pmalcolm Posted March 24, 2011 Author Share Posted March 24, 2011 mr wilson u are a man of knowlage, thanks for the help Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted March 26, 2011 Author Share Posted March 26, 2011 Sorry to post up on this again, but if there as been DOT3 or 5 used on the car atm (as i dont think there is a test to check) would it matter if i used DOT4 and it mixed?

monsween Posted March 26, 2011 Share Posted March 26, 2011 Try and not mix it. Be better to try and flush the system Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted March 27, 2011 Author Share Posted March 27, 2011 (edited) Well went to fit the caliper today and it as the wrong one so gotta take it back and wee that they can get ...It seemed the same in the box from non piston side. Look at the difference: http://img52.imageshack.us/img52/4364/20110327002.jpg http://img821.imageshack.us/img821/8523/20110327003.jpg http://img402.imageshack.us/img402/3280/20110327004n.jpg Wonder what caliper its for? P.s: Bleeding went well, 1st time ive doen it. Bought this bleed kit from Halfords for a fiver. Came with the pot, 1 way valve pipe and worked a charm!

Scott Posted March 27, 2011 Share Posted March 27, 2011 You are only changing the one caliper? Make sure your other one is good bud, the brake balance will be all over the place if it isn't perfect (spin under heavy breaking). Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted March 27, 2011 Author Share Posted March 27, 2011 Just the one caliper scott as this one is sticking mate. Other seems ok, If i get problems i will change the other,thanks for the advice pal Quote Link to comment Share on other sites More sharing options...
Scott Posted March 27, 2011 Share Posted March 27, 2011 Just the one caliper scott as this one is sticking mate. Other seems ok, If i get problems i will change the other,thanks for the advice pal Test it VERY carefully. You will have one VERY slick and FULLY biting caliper on the rear quarter, vs 3 slightly, sticky slightly gungy, used and worn biting calipers around the other corners. Think about it bud, the rear corner braking harder and faster than the rest of the 3 corners when you are at speed. I'm not saying it will be a problem, just that it could be a VERY serious problem VERY quickly, I don't want to see any "I've binned my car" or worse threads due to not being informed. Tread carefully at first just to make sure Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted March 28, 2011 Author Share Posted March 28, 2011 Will do pal. Never thought about it like that. Thanks again for your time Quote Link to comment Share on other sites More sharing options...
