Mark Ayling Posted November 7, 2002 Share Posted November 7, 2002 The Supe started p*ssing oil yesterday, at quite a rate - took it to Woodcock Hill (garage near JIC who look after all their cars) and it turned out to be the oil switch (sensor-thingy). They managed to get hold of one and fit it today, £145 parts and labour! Not bad as I turned up there this morning unannounced, would recommend them to anyone. Anyway, the point is (back to subject) that I was without the Supe for the day, so I hired a Rover 400 (new shape) to get around in and it has made me realise how crap the standard J-spec brakes are on the (my) Supra! I couldn't believe how good the Rover was at stopping, it took me a while to get used to the bite on them, nearly smashed my teeth on the steering wheel a couple of times! So....are the J-spec brakes really that sh*t, or is it just that perhaps mine are shagged? I did do a very heavy track day recently, but I had the front pads changed the day before I did it - could it be that I didn't "bed them in properly" before caning them (if you have to do that) or could they just be generally knackered...? Either way, this is all academic really as I can't afford to do anything to the Supe at the moment, this house-buying business is frigging expensive!

MONKEYmark Posted November 7, 2002 Share Posted November 7, 2002 i had my jap brakes on for ages and you get used to them.then i got some standard jap pads fitted at cw`s for the time been till i get my uk rears to go with uk fronts,and i thought the new jap pads were loads better than the old jap pads that had come off.they stop quite well i think.maybe not good for a track day but for normal driving they seem ok.wonder if all they hype over uk set up is all its cracked up to be. track day will eat through pads in no time. cant you buy uprated race pads for j-spec brakes that are supposed to be as good as a standard uk set up? i need to get a rear uk set up to upgrade the brakes to uk spec.anyone know of a price of uk rear discs & calipers Quote Link to comment Share on other sites More sharing options...
ChrisR Posted November 8, 2002 Share Posted November 8, 2002 Mark, Chris Wilsons Race Pads are very good, they squeal but are well worth it, Have only had mine two weeks now, i couldnt believe the difference. If you are into track days it may be worth considering, only thing that may put you off is the £285 price tag, however, Stock pads must be at least more than half that price anyway.

Matt Harwood Posted November 8, 2002 Share Posted November 8, 2002 Mark, I'm of the opinion that J-spec brakes are utter shite, but to be fair, I never tried uprated pads. I've changed my setup to the UK brakes and the difference is quite amazing. Imagine putting uprated pads in them! I know you're not exactly local but you're welcome to take my car for a spin to decide for yourself Quote Link to comment Share on other sites More sharing options...
Neil Sandham Posted November 8, 2002 Share Posted November 8, 2002 Not sure on the price of J-spec OEM pads but UK OEM pads are just £55+vat a set. I never had any problems with them but of course that doesnt mean they couldnt be improved ! cheers Neil. Quote Link to comment Share on other sites More sharing options...
ChrisR Posted November 8, 2002 Share Posted November 8, 2002 £55+vat a set You mean fronts, yes. Chris Wilsons are for a full set and i believe it is recommended they are fitted as a full set. The Race pads are really for those who dont want to go for UK Spec Brakes. Regards Chris Quote Link to comment Share on other sites More sharing options...
Neil Sandham Posted November 8, 2002 Share Posted November 8, 2002 Stock pads must be at least more than half that price Around £55 per axle. (approx 110 full car (me genius)) + fitting of course I too have some of CW pads all round (intermediates). - my evaluations are still on going. Cheers Neil.

Neil Sandham Posted November 8, 2002 Share Posted November 8, 2002 Originally posted by Chris Rimes i believe it is recommended they are fitted as a full set. Regards Chris True and if you can afford it then do but a rather puristic approach me thinks. The work rate of the rear calipers is much smaller than the front especially in a car like the supra where the bias has deliberatley been engineered to the front to prevent rear wheel lock up and the back end flipping round. - helps out the noddy drivers Cheers Neil.

FaithStalker Posted November 8, 2002 Share Posted November 8, 2002 i have to step in here and stick up for jspec brakes, mine have been excellent since i bought the car, and the look stock and have been told they are stock, dunno what pads are on them - they dont half squeal when cold / wet but in normal conditions no noise at all, lots of brake dust though, saying that i do drive like a p**sy, just ask chris,justin,terminator, and everyone else in the convoy to and from stevenage!

Raoul H Posted November 8, 2002 Share Posted November 8, 2002 I got my uk brakes fitted at TorqueIC and I must admit to there being a marked difference in feel i.e. bite, and performance. I've had occassion to do some high speed braking and where the J-spec brakes would definitely have faded, the Uk brakes just keep on delivering. I'm not saying the J-spec brakes are rubbish, rather that they are not best suited (race pads notwithstanding) to the really vigorous driving that some of us may indulge in from time to time. As for race pads, well I indulged in a set of porterfield race and found they wore out pretty quickly much more quickly than my previous stock pads. Go figure...and that was without seeing any track action! Best to use pads for the intended purpose. Rgds, Quote Link to comment Share on other sites More sharing options...
WILLGILL Posted November 8, 2002 Share Posted November 8, 2002 dare I say it but mine dont even have ABS, I've been hiding the fact I have by far the cheapest Supra I must say they are very spongy but tbh its a heavy lump they have to stop and they are highly progressive. no qualms here and I still drive like a nutter Quote Link to comment Share on other sites More sharing options...
Terminator Posted November 8, 2002 Share Posted November 8, 2002 Originally posted by ajefford ............................... i do drive like a p**sy, just ask chris,justin,terminator, and everyone else in the convoy to and from stevenage! I would not agree with your statement, you were just a little more cautious on the damp twisty bits. My impressions of my new UK brake setup on SS hoses, racing fluid and stock pads is obiviously subjective, but several of the guys said that they were amazed at the power of the braking on my car, when following me to Stevenage. I have alsonoticed in dual carridgeway braking in emergency situation, I can out brake most things, including top of the range BMW's and Mercs. My main concern now is getting rear ended. The othewr difference I have noticed is that ABS kicks in. On my stock pad Jap brakes it never worked, I actually thought it was broken. Th only way to settle this is to put cars side by side at the same speed and slam on the anchors, I know reaction time comes in to it but it should give a good indication. Or we use four cars, Jap stock pads, Jap CW race pads, UK stock pads and UK race pads. All four drivers dive all cars and we measure distance, should put this one to bed once and for all. Failing that I know a friendly MOT tester who might be up for letting us a set of rollers. Justin you know who I am talking about we could, at least comppare stock UK and Stock Jap.

I'll pick up on this and say that I thought new pads have to be bedded in over a hundred or so miles of normal driving, with as little hard usage of the brakes as possible - could it be that you now have a glazed layer on the pads? -Ian Quote Link to comment Share on other sites More sharing options...
Need4Speed Posted November 8, 2002 Share Posted November 8, 2002 J-spec brakes agian... a bit of bête noire with me I'm afraid. How bad are they? - Worse than my fiesta van's brakes by a country mile. It's hard to believe a disc brake that big can't stop a Supra. As brakes go, they make good paperweights!

You don't drive like a p*ssy mate. I saw you go after that Volvo into the bend! I remember because at the time I thought to myself 'what a mad f*cker' About J-Spec brakes I would say that if you have gone fully de-catted and bigger bore exhaust ie 18 psi then this was when I noticed that my usually solid stools became quite runny. (That means that the brakes didn't stop me very quickly and I shat myself on a couple of occasions) I would probably go for uprated CW front pads even though they do sound a little bit like scraping your finger nails down a blackboard.
