Supra_Sean Posted April 19, 2010 Share Posted April 19, 2010 Ok i was look at this topic http://www.mkivsupra.net/vbb/showthread.php?t=215393 and seen my rear discs are drilled and grooved so are not standard, Are these just drilled and grooved upgrade or bigger brakes ? Only asking cause i just brought some 2nd front discs and if the rears are bigger is it ok putting standard front discs on ? Best pic i have at this time Quote Link to comment Share on other sites More sharing options...
Nic Posted April 19, 2010 Share Posted April 19, 2010 Looks like the stock smaller 1pot rear brake calipers with aftermarket discs. A better pic of the caliper would confirm. Quote Link to comment Share on other sites More sharing options...

Supra_Sean Posted April 24, 2010 Author Share Posted April 24, 2010 Right well to get to the point my brakes are crap, They vibrate, rub, squeek, And think they are warped so i think its best i get new discs and pads all round. Just not sure what ones to look at that will fit mine. Is it worth doing the calipers aswell ? Quote Link to comment Share on other sites More sharing options...
imi Posted April 24, 2010 Share Posted April 24, 2010 (edited) Sorry to the be the bearer of bad news... Standard Jspec Calipers (front and back) with Jspec sized discs (albeit a fancy drilled one for one axle) Some decide to upgrade to the UK Brake setup - which will give you a noticeable performance upgrade. Other stick with the jspec setup but keep to stock discs (brilliant quality) - good fluid, lines and excellent pads. the leftovers consider the likes of K-sport brake due to their 1 zillion pots and bright colours. Which one are you Edited April 24, 2010 by imi (see edit history) Quote Link to comment Share on other sites More sharing options...

Which one are you Brakes are the only thing between you and the tree infront of you so when it comes to it i dont need fancy looking things just need to stop with ease. Altho i dont think my new wheels will clear uk brakes the rear brake discs look new, what are the pads like much life in them, do they look new. b I did try to have a look while the wheels were on but cant really tell, however, It seems the shit braking is coming from the front Smaller Thanks Quote Link to comment Share on other sites More sharing options...
Nic Posted April 24, 2010 Share Posted April 24, 2010 Fronts are the smaller 2 pot calipers with 296 x 32mm discs. Rear are the smaller 1 pot calipers with aftermarket 307 x 16mm discs. If you are having problems with them get them checked ASAP. To get the best out of them I would replace the discs all round with new OEM Toyota ones, fit a set of quality aftermarket brake pads, replace the brake fluid and fit a set of braided Goodridge brake lines. Fitting a brace for the master cylinder will also help firm up the pedal feel. Quote Link to comment Share on other sites More sharing options...

Nic Posted April 24, 2010 Share Posted April 24, 2010 Would these be any good with some braided Goodridge brake lines ? Braided brake lines and more so a brace for the brake master cylinder will significantly firm up the pedal feel ie. make them feel less spongy.

Supra_Sean Posted April 24, 2010 Author Share Posted April 24, 2010 Discs are warped tho i think so i wanna get it all done and might aswell get better parts for better braking. Quote Link to comment Share on other sites More sharing options...
monsween Posted April 24, 2010 Share Posted April 24, 2010 Just a query, you mention bigger or smaller j-specs? Don't they just do J-spec and Uk-spec? Or is there such a thing as a big j-spec set up? Quote Link to comment Share on other sites More sharing options...
Nic Posted April 24, 2010 Share Posted April 24, 2010 (edited) Just a query, you mention bigger or smaller j-specs? Don't they just do J-spec and Uk-spec? Or is there such a thing as a big j-spec set up? There were 2 factory brake options on the Supra Larger Brakes Front - 4pot Calipers, 323x30mm Discs Rear - 2pot Calipers, 324x16mm Discs Smaller Brakes Front - 2pot Calipers, 296x32mm Discs Rear - 1pot Calipers, 307x16mm Discs All UK spec Supras were factory fitted with the larger brakes. J-spec Supras were factory fitted with either the larger brakes or the smaller brakes, depending on the model and year. The larger brakes often get referred to as UK brakes, but as they were also factory fitted on many J-spec Supras (actually a lot more than were fitted to UK Supras) the term is confusing.

Supra_Sean Posted April 24, 2010 Author Share Posted April 24, 2010 Yeah good help that post as i was unsure on what different sorts of brakes the Supras had. Would it be worth me fininding some bigger j-spec brakes ? Quote Link to comment Share on other sites More sharing options...
