SteveC Posted September 4, 2008 Share Posted September 4, 2008 Does anyone know if stainless steel brake caliper pistons are available (front and rear) for a UK Supra? I'm sure I've seen them mentioned on here somewhere, but cannot find the post again - although I'm quite sure there wasn't any price mentioned, or who sells them. I've got my calipers in bits at the moment and there's some rust on the pistons. I could just clean them up, but I suspect that they'll soon corrode again and new pistons would probably be a better solution... and stainless pistons would be better still. Any ideas? Thanks.

SteveC Posted September 5, 2008 Author Share Posted September 5, 2008 Well, on the face of it, it looks like stainless steel caliper pistons are not available for standard UK brakes - at least going off the lack of replies here and from my enquiries elsewhere. I've now ordered a set of 12 standard pistons from Toyota, and just for reference for anyone else doing the job, fronts are (at the time of posting) £15.76 + VAT each and rears are £12.70 + VAT each - making a total of £207.83 inc VAT. If you speak to your local Toyota dealer nicely then they'll hopefully give you a bit of discount on top of the prices mentioned above.

Chris Wilson Posted September 5, 2008 Share Posted September 5, 2008 The stock pistons are hard chromed, so once that goes they rust like Billy O. You could have stainless ones made, but why? Stock ones in unrusted bores with intact dust / water boots with fresh fluid are good for 200K miles plus. Quote Link to comment Share on other sites More sharing options...
SteveC Posted September 5, 2008 Author Share Posted September 5, 2008 With having seen stainless caliper pistons mentioned, I thought it wise to make an enquiry before shelling out the biggest part of £200 for stock ones. If the originals had lasted 200k miles, then I wouldn't be in this position now! Obviously the seals must have perished a little, even though they looked ok. Hopefully the calipers will be good once cleaned up, painted and re-assembled. Quote Link to comment Share on other sites More sharing options...
dandan Posted September 5, 2008 Share Posted September 5, 2008 Is a simple rebuild kit available from Toyota for UK specs with pistons and seals? Quote Link to comment Share on other sites More sharing options...
SteveC Posted September 5, 2008 Author Share Posted September 5, 2008 It would seem that a combined kit of caliper pistons and seals is not available from Toyota, but the price for the seals alone is £36.73 + VAT for a front or a rear set (both sides), plus, of course, the prices quoted above for the pistons. Again, on the seals you may be able to get a bit of discount on those prices. Quote Link to comment Share on other sites More sharing options...
dandan Posted September 5, 2008 Share Posted September 5, 2008 Wow - I didn't realise that £200 was for the pistons.....if someone can get me a brand new one I'll get some made is stainless! Quote Link to comment Share on other sites More sharing options...
bromy Posted September 5, 2008 Share Posted September 5, 2008 I can machine them from 316 if you need. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 5, 2008 Share Posted September 5, 2008 Why not titanium, and have less heat transfer? Quote Link to comment Share on other sites More sharing options...
bromy Posted September 5, 2008 Share Posted September 5, 2008 Why not titanium, and have less heat transfer? No problems, if you wish to buy the material;) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 5, 2008 Share Posted September 5, 2008 What sort of tip would you turn Ti with? I have never tried turning it, it galls easily doesn't it? Quote Link to comment Share on other sites More sharing options...
bromy Posted September 5, 2008 Share Posted September 5, 2008 Nothing scary about machinng Ti, a lot of sub con companies shy away from the exotics. We produce sub-sea valves from hastalloy, inconel, incalloy etc with relative ease. It's all about correct speeds and feed, tool geometry and coatings has come a long way over the years. Ti is quite a pure clean material so the spec does not alter greatly as like stainless where the spec is very wide so cutting data can alter wildly.

Chris Wilson Posted September 5, 2008 Share Posted September 5, 2008 I'm talking 1960's Harrison 11 inch swing lathe here, not some CNC machining centre... I take it I would need ceramic tipped tools? Cheers. Quote Link to comment Share on other sites More sharing options...
