Jim_1979 Posted April 24, 2008 Share Posted April 24, 2008 I've noticed the past few days a sorta brake smell when I've stopped driving. I initially thought that it must be because I've been driving quite hard. I just popped out to the shop and when I stopped I could smell it again! I went round all corners of the car smelling. I also touched the discs on all corners. All were fine apart from the rear right. The disc was stupidly hot and smelly!! It doesn't feel like it's seized fully on when driving etc. I used to own a Mr2 turbo and both the rears seized up and I could hardly move. What are my options here? Is there an easy ... "just tap that bit there" fix? There's alot of life on the pads themselves. Will I need a new caliper, or is it repairable? Also, what about the disc? Cars eh? ... lol. Money pits!!!

Swampy442 Posted April 24, 2008 Share Posted April 24, 2008 Itll be a seized piston or slider pin, dont drive too far or you'll fook your disc (if you havent already) or in extreme cases have fire!! Strip it down and see whats what Link to comment Share on other sites More sharing options...
Jim_1979 Posted April 24, 2008 Author Share Posted April 24, 2008 Erm.... I drove about 200miles today. That bad? How easy is it to strip it down? Is there a guide anywhere? I've done alot of things with cars, but calipers aren't one of them. Link to comment Share on other sites More sharing options...
Homer Posted April 24, 2008 Share Posted April 24, 2008 As above really. The rear sliding callipers on supra's are really suffering from these seizures on the older cars, it's becoming more and more a problem. The most common cause seems to be one of the slider pins corroding and causing them to freeze themselves to the calliper. The only real way to fix this is to strip and rebuild the calliper. Ideally, if you're replacing the pins it would be a good idea to swap the piston at the same time. It's actually not that difficult so long as you can wield a spanner and have a bit of common sense The pistons, seals and slider pins are not all that expensive to buy from Toyota. If you need them, I recently posted up part numbers and exploded diagrams on a thread for Chris Wilson. Link to comment Share on other sites More sharing options...
peter richards Posted April 24, 2008 Share Posted April 24, 2008 exactly the same with mine , if you can replace it with new do so as second hand , chances are they wont last to long either , so false economy . jody T is the man give him a pm he sorted mine out at a very reasonable price . i did both sides as sods law the other one would have done the same , i was lucky the discs were ok Link to comment Share on other sites More sharing options...

Swampy442 Posted April 24, 2008 Share Posted April 24, 2008 If you can twiddle a spanner, checking the pins are easy. Wheel off, back of the caliper are 2 bolts (12 or 14mm) whip them out then slide the caliper upwards. The pins should stay in the carrier part of the caliper. Remove them and check condition, apply copper grease and refit, or replace Easy Link to comment Share on other sites More sharing options...

As for the pins... anyone any pics, or how do you remove them etc? Sorry if I'm an ass pain!! Link to comment Share on other sites More sharing options...
Swampy442 Posted April 24, 2008 Share Posted April 24, 2008 The pins sit in a rubber gaiter, just give them a pull and they should slide out, providing theyre not seized. If the pins are free then its the piston in the caliper thats siezed and its rebuild time. I dont have any pics, sorry mate Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 24, 2008 Share Posted April 24, 2008 I keep pins, anti rattle rubber bushes, and the pin gaiters in stock, front and rear. Link to comment Share on other sites More sharing options...
