Lude Posted October 9, 2011 Share Posted October 9, 2011 ive changed brake pads on about 10 cars, easy enough job, i removed the rear calliper on my supra, (they split in half when botls were un done) however brake fluid continually dripped out? thinking they should have just swung up as on most cars, but why does the fluid drip out? sorry to sound such a noob ive done quite a few technical mechical things Quote Link to comment Share on other sites More sharing options...
Scooter Posted October 9, 2011 Share Posted October 9, 2011 exactly what bolts did you undo? and do you have the smaller or larger spec brakes? Quote Link to comment Share on other sites More sharing options...
Lude Posted October 9, 2011 Author Share Posted October 9, 2011 UK brakes, i cant remember which ones now mate, think they were two on the outside of the caliper, 14mm, i removed the caliper as i was re-tapping the threads on a wheel stud changed brakes loads of times just puzzled why the fluid came out of this car only?

Rob Posted October 9, 2011 Share Posted October 9, 2011 When you say, "split in half" what spilt? The metal casting of the caliper? Quote Link to comment Share on other sites More sharing options...
Lude Posted October 9, 2011 Author Share Posted October 9, 2011 (edited) as in the caliper, each side of the brake pads, like this (the 2 largest items in this pic the caliper) split so they are 2 seperate items http://www.motormadness.net/images/v8cortina/caliper_split.jpg the fluid dripped out when i split them, i asume this is normal, i split them on accident, as wanted to just take them off as one to get access to the wheel studs, when need to change the brakes i only need to swing the whole lot upwards instead of splitting, Edited October 9, 2011 by Lude (see edit history) Quote Link to comment Share on other sites More sharing options...
Scooter Posted October 9, 2011 Share Posted October 9, 2011 I think you've undone the wrong bolts? the uk calipers never split in half when normally removing the caliper, they just lift off the disk after removing or prising back the pads. I think its x2 17mm bolts on the inside of the caliper/hub. I think Chris wilson has now got the rubber seals that go between the two halfs I think you have undone and you'll probably need these before refitting.

Rob Posted October 9, 2011 Share Posted October 9, 2011 (edited) Ah, so UK spec brakes. I think you've over egged it a bit there, you only needed to undo the sliding, mounting bolts to the rear to allow the caliper to swing up. You've effectively dismantled the whole caliper. Without checking, I think there will be new gaskets required to reassemble. Check the maintenance docs to confirm. You need to do a full refurn now to rebuild them, with new grease, boots etc etc/ The reason fluid leaked out is because you opened up the body of the caliper. You'll need a full bleed now too. Hope you don't want to use the car tomorrow. Edited October 9, 2011 by Rob (see edit history) Quote Link to comment Share on other sites More sharing options...
Lude Posted October 9, 2011 Author Share Posted October 9, 2011 ah right ok thanks. i re-assembled them and put back on, needed bleeding obviously, but ok then no leaks. i actually did this about a month ago, but only now posting as i have to remove again to change the pads. thanks for the tips, Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted October 9, 2011 Share Posted October 9, 2011 for the pads you dont have to remove the caliper atall. jus remove the pin and slide them up . caliper can stay completely in place Quote Link to comment Share on other sites More sharing options...
skippyboyo1 Posted October 9, 2011 Share Posted October 9, 2011 real easy job mate 2 bolts loosen one and remove the other and just flip them up and change them Quote Link to comment Share on other sites More sharing options...
dude Posted October 9, 2011 Share Posted October 9, 2011 Dont be taking this the wrong way but do you honestly think you should be doing work like this when you clearly do not have a clue, I don't even like splitting calipers and you have done it whilst changing pads, you could prob not have got htis somewhat safety orientated job more wrong, have you changed the o rings etc and assembled the calipers correctly ?? People like you are what causes bad accidents you have a 160 +++mph car yet have no clue as to what you are doing, this post beggars belief.

I'd seriously consider renewing the seals between the two halves of the caliper. If it fails, it will fail under extreme braking, and you don't need me to tell you what'll happen then. You've broken the caliper open, OK that was a mistake, but don't make an even bigger one now. Re: Dude's right too. Get it sorted before you kill yourself or someone else.

d_d Posted October 9, 2011 Share Posted October 9, 2011 I agree, you say you have changed brake pads on about 10 cars, Yet its very straight forward and no different on the supra. I hope the other 10 cars dont have no problem!!!! Quote Link to comment Share on other sites More sharing options...

Lude Posted October 9, 2011 Author Share Posted October 9, 2011 when spliting them, i wasnt even changing the brakes, i was removing the whole lot to get at the wheel stud, this was done around a month ago, maybe 2 months, was all clean and put back together, bled and then fine. no leaks.. will be carefull not to split again..

Dnk Posted October 9, 2011 Share Posted October 9, 2011 It would pay you to read the WSM when doing jobs on your car, the brakes have a very good section showing you exactly what to do to remove the calipers or change the pads along with several other sections covering most parts of the car with very good diagrams Quote Link to comment Share on other sites More sharing options...

dude Posted October 9, 2011 Share Posted October 9, 2011 If you have not used a rebuild kit on the caliper it is an accident waiting to happen, it will prob only fail if you hit the brakes really hard but of course thats when you prob will want it to be working, the good news is if you were to unfortunatley kill someone it would now go from being an unfortunate accident to prob manslaughter as you would be directly responsible by your actions. If you seriously could not figure out the caliper is bolted on with 2 bolts behind the hub then you really should put your spanners on ebay, the worrying thing is someone is going to buy this car one day !!!! Some of the things ive seen lately have made my toes curl re workmanship and safety etc. I myself almost killed god knows how many people when a Lotus I picked up from a dealer lost all its brakes, this was because some idiot who thought he knew what he was doing sleeved a brake PIPE with a rubber pipe and 2 jubilee clips, so do I think im making a big deal about it???? No and neither did the car dealer or the idiot with the screwdriver when I got hold of him. Like I said sell the spanners and let someone who knows what they are doing work on your car.

Lude Posted October 9, 2011 Author Share Posted October 9, 2011 what does the rebuilt kit consist of, new seals, anything else? Quote Link to comment Share on other sites More sharing options...
dude Posted October 9, 2011 Share Posted October 9, 2011 There will be few o rings and the seals on the pistons really should of been changed, the upside is the caliper SHOULD end up like new, I would rather you posted me the caliper and I'll put the kit in foc, I DO NOT ever offer to rebuild calipers as the ramifications of a problem do not bear thinking about and I have done enough questionable things I would not want another avoidable one on my conscience. The one thing you need to know works is the brakes. Like I said if you need help I'll do it for you, all it will cost is the postage.
