paddynewman Posted January 9, 2011 Share Posted January 9, 2011 Noticed my Supra was dragging to one side and really gulps fuel, smells when I get out of it after a hard drive and has an odd rumble/donk noise when sub 40mph. The drivers side rear caliper seems to be seizing, which is evident in the lack of pad material passenger side has brand new pads with atleast 90% of the pad left, drivers side was pretty much metal on metal action. Replaced the pads and cleaned up the caliper, flushed all the crap out and the like. Brother did some work on it (see below) and its currently seized again Are there any caliper refurb kits around? That or how much are calipers going these days/any aftermarket ones? BUT!!! Had it in the garage for a full decat, the sound isnt too bad, its not louder as such, until around 3k rpm. What it has done is made the sound a smoother drone not a raspy sound, which I was getting sick of Only thing is the OEM shield that covers the headers needs modifying to stop this little rattle on the decat pipe. Was up for sale for a modest £2199, but I may end up keeping it...if I do, how simple/cost effective is converting my NA to a turbo, not needing it, but if I keep it as a long term thing, i'd like to do it!

Dnk Posted January 9, 2011 Share Posted January 9, 2011 (edited) Are these j spec brakes ? if so it could either be the piston seizing or the sliding pins, if its not the sliding pins then it will be the piston seizing, if its the piston then the outer seal possibly has a hole or split in it letting dirt and moisture get in behind it. This would need to be changed along with popping out the piston to inspect it for pitting or corrosion, Toyota sell the seal kits and 1 kit will do both rear calipers. £40-£50 If their UK spec calipers then it will be the piston/pistons seizing. Also if you have a problem with one caliper its well worth doing an inspection on the others as all the outer seals or boots as their called will be in similar state and they really should be changed.

paddynewman Posted January 9, 2011 Author Share Posted January 9, 2011 Greased all the sliding areas, really went over them thoroughly. Im guessing if I pope the pistons out and have a look at the seals, i'd have a better idea of whats up. May as well do both calipers while im there Likely to have them in stock, i'll aim to do it whilst my interior is being flocked. Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 9, 2011 Share Posted January 9, 2011 You can take the outer seals/boots off without removing the pistons, if you have to remove or change the piston then replace the inner seal as they come in the kit and very easy to swap.

paddynewman Posted January 9, 2011 Author Share Posted January 9, 2011 I'll check the outers, if they are ok i'll probably pop the pistons on the dodgy caliper, I have a feeling the seals could be totally shot. Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 9, 2011 Share Posted January 9, 2011 How olds the car ? if their the original ones that the car came with i'd change the outer seals on all of the pistons, it'll stop you getting any problems in the future and inner seal failure is very rare and usually due to a damaged corroded piston.

paddynewman Posted January 9, 2011 Author Share Posted January 9, 2011 No idea if they have been touched before, 1994 import NA auto. I'll change the outers for sure then. Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 9, 2011 Share Posted January 9, 2011 A good clean with brake cleaner while your doing it will be a good idea too Quote Link to comment Share on other sites More sharing options...
