lockys96 Posted November 22, 2007 Share Posted November 22, 2007 I have some questions about brakes, non of which relate to a supra, but mr2 - please move mods, if u so wish:) ive been looking everywhere for brake combo's, front and rear. even got to the stage about thinking of d2 brakes. but now i have come accross 2 kits. 1. AP-Racing 4 pot kit, all the specs relate to supra oem size its very reasonable priced at £970 delivered. http://www.deck-japan.co.jp/AP%206POT.jpg http://www.deck-japan.co.jp/AP6S.jpg 2. Brembo 4 pot F50 brake kit with 340mm discs £1,494. http://www.hirano-tire.co.jp/border/border28-1.jpg i have read many posts about ure top 3 brands, and both above are included. is it worth spending the extra £500 for the brembo kit? AP-raing dont list the a mr2 kit, but have a new one ready in 6weeks time, the kit is from japan, and i asume replacement discs and pads are easy to come by. i cant find many rear kits though, so will probably look to run a brake offset kit with endless pads Quote Link to comment Share on other sites More sharing options...
Wez Posted November 22, 2007 Share Posted November 22, 2007 Do you have more info on the AP kit that uses stock size disks? Quote Link to comment Share on other sites More sharing options...
michael Posted November 22, 2007 Share Posted November 22, 2007 Some years ago I setup an ongoing deal with Red Dot for an MR2 specific Brembo kit, it was advertised on IMOC's old site but wasn't carried through to the new one. http://www.reddotracing.co.uk/reddot.asp It was a 4 pot kit for £750 plus VAT (this included a 20% discount for members) 326mm discs and various colour and disc options - may be worth asking if they still do it. http://web.archive.org allowed me to find the info but it's a bit lacking, a few people got the kit and were very impressed.

lockys96 Posted November 22, 2007 Author Share Posted November 22, 2007 thanks mic, will check it out. i take it its brembo calipers, and red dot everything else wez http://www.deck-japan.co.jp/AP%20List.htm may need to translate Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 22, 2007 Share Posted November 22, 2007 You should wait for, or have built, an MR2 specific kit. A mid engined car has TOTALLY different brake bias requirements to a front engined car. I believe I may still have some race pads for stock MR2 calipers, but can't recall if they are early or late type. Nailing on a Supra based kit will not work well.

I believe I may still have some race pads for stock MR2 calipers, but can't recall if they are early or late type. Nailing on a Supra based kit will not work well. it means the caliper is the same size as supra, but the kit is designed for the mr2. i understand about brake balance. if i fitted the ap-4pot front kit, and fitted rear brake offset kit, which runs brembo larger discs, with race pads, not work? simon Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 22, 2007 Share Posted November 22, 2007 Are they DESIGNED to work together? I suspect not, and if so, you need to do the maths on the brake balance, which is involved and never very accurate. You don't have dual master cylinders and a bias bar, do you? If not the balance is in the sizing and any alterations would have to be made with pressure limiting valve, which is crude and horrible.

lockys96 Posted November 22, 2007 Author Share Posted November 22, 2007 i want brakes that will work. i dont have a 10k budget:D Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 22, 2007 Share Posted November 22, 2007 The later stock brakes will work, even on track, with the right fluid and pads. So will J-spec Supra brakes. Just depends what you need / expect. What's the car used for? On the road stock brakes will be fine with good pads and fluid, anything more is nice, but unnecessary.

lockys96 Posted November 22, 2007 Author Share Posted November 22, 2007 want to do track days, but not at competition level. i have a gen 3 mr2 96, so brakes are the later ones. but they dont match the perfomance of the car Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 22, 2007 Share Posted November 22, 2007 They will with some decent pads and fluid, if it's just fun trackdays. You could even make them live under full race conditions if you had to. What pads are in them? Quote Link to comment Share on other sites More sharing options...
lockys96 Posted November 22, 2007 Author Share Posted November 22, 2007 all oem at the moment. what if i stole a 4-pot uk spec fronts and 2pot rears from the supra. and then ran good pads. it should be not that hard to modify Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted November 22, 2007 Share Posted November 22, 2007 Its likely dead easy to modify, but its doing it right thats hard. Doing it properly will not be cheap BUT it will give good results. Quote Link to comment Share on other sites More sharing options...

It won't be at all satisfactory. It's a complex subject, and 9 times out of 10 people end up paying someone else to do it that's used to brake design, or buying a commercial kit. If you have decent machine shop facilities it's possible to fabricate everything, but if you have to pay someone a kit will be far cheaper. Doesn't the MR2 have the h/brake mechanism built into the rear calipers? have you considered how you will have a handbrake if you put "normal" calipers on the back?

lockys96 Posted November 22, 2007 Author Share Posted November 22, 2007 yes it does chris. so i will firstly upgrade oem rota's, pads and lines all round please recomend. i dont want naff ones Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 22, 2007 Share Posted November 22, 2007 Stock discs, Performance Friction pads in 01 compound (or 96 compound), SRF fluid, Goodridge or similar hoses. Remove back plates, try and duct air to the eyes of the discs. Quote Link to comment Share on other sites More sharing options...
