Ark Posted January 29, 2009 Share Posted January 29, 2009 I've been looking at brake upgrades for this years trackday season and have boiled it down to AP 6-pots or Brembo 6-pots...except that the Brembos will cost more than £700 more than the APs. Even downgrading to Brembo 4-pots (not monoblock callipers) will cost more than £300 more than the APs. So, why are they so much more expensive? Would I really notice any difference, given that APs are generally considered to be "the b0ll0cks"? Quote Link to comment Share on other sites More sharing options...
Wez Posted January 29, 2009 Share Posted January 29, 2009 Alcon are also pretty good Quote Link to comment Share on other sites More sharing options...
Ark Posted January 29, 2009 Author Share Posted January 29, 2009 Yeah, but they don't sell a Supra-specific kit (at least they didn't when I started looking into this). If it's not coming straight off the shelf, then I can't doing with it. Quote Link to comment Share on other sites More sharing options...
SimonB Posted January 29, 2009 Share Posted January 29, 2009 So, why are they so much more expensive? Would I really notice any difference, given that APs are generally considered to be "the b0ll0cks"? I'd prefer the APs myself I think. Where are you looking at getting them from? Last time I looked the APs were pretty much the same price, at least the bigger 6 pot APs were, but that was a while ago. Quote Link to comment Share on other sites More sharing options...

TLicense Posted January 29, 2009 Share Posted January 29, 2009 That's very odd. Expecially seeing as they're the same kit. Brembo own AP and the kit is as far as I've been able to tell identical. Goes to show how much red paint costs.... Quote Link to comment Share on other sites More sharing options...

bignum Posted January 29, 2009 Share Posted January 29, 2009 What brakes do you have atm, wouldn`t uk`s with decent pads etc be up to it? Quote Link to comment Share on other sites More sharing options...
Ark Posted January 29, 2009 Author Share Posted January 29, 2009 What brakes do you have atm, wouldn`t uk`s with decent pads etc be up to it? UKs with Endless pads and 5.1 fluid. They work, but I keep warping the disks. If I use a stronger disk, I boil the fluid. If I use a softer pad, I melt them instead...I just want it stronger all round...

Most juddering or so called 'Warping' is nearly always down to some other factor such as rust (between disk and hub), pads not bedded, wrong pads, hubs damaged etc Once any of these outside influences are employed your disk is only a small step away from being scrap!! as DTV takes over and starts a very damaging process http://www.powerbrake.co.za/downloads/tech_01_judder.pdf This is worth a look see Edited January 29, 2009 by rick001 (see edit history) Quote Link to comment Share on other sites More sharing options...
Alex Posted January 29, 2009 Share Posted January 29, 2009 Warping is caused by uneven heating or cooling of the disks. Ie the area thatis covered by the caliper when stationary cools at a different rate to the section not covered. This difference leads to warping.

JamieP Posted January 29, 2009 Share Posted January 29, 2009 I can recomend the Brembo's, they are amazing brakes, ive had AP big brakes kits on both the evo 9gt and my Monaro and both times the discs warpped in a short amount of time.

Ie the area thatis covered by the caliper when stationary cools at a different rate to the section not covered. This difference leads to warping. I believe this is only part of the story. This doesn't explain why you can start a braking manouvre with good pedal feel and end it with the pedal trying to kick your knee into your teeth. Sometimes the discs are 'warped' from cold but othertimes they require a good heating before they exhibit ill signs. However it is caused UK brakes cannot withstand repeated braking manouvres without fading the pads (fast road) and 'warping' the discs. If you use racing pads the discs will still 'warp', but the pads are capable of grinding them true again with persistence. This unfortunately comes at the expense of wheel and paintwork finish. This is my experience anyway. Quote Link to comment Share on other sites More sharing options...

4packet Posted January 29, 2009 Share Posted January 29, 2009 Thanks for that, very interesting and well worth reading Agreed - good article. DTC cause no. 4 is the problem I have repeatedly seen with my discs. Have never seen an image showing the effects of a thick/thin disc before, but it matches mine. Fast road pads exceed 610degC, so you will have this problem if you continue to run the brakes on their limit. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 29, 2009 Share Posted January 29, 2009 Greddy kit is made by Alcon. Lovely calipers, lovely discs. I think Alcon UK do offer a supra specific kit though, probably cheaper than buying the Greddy boxed stuff. Quote Link to comment Share on other sites More sharing options...

They don't list the Supra on their website (unlike other mighty titans of the motoring world, like the Vauxhall Astra) Rob the sales guy is pulling together a price but he is telling me it will prob be have to be at least 5 kits for a run so when i get the info i will need to talk to Mawby about a group buy as a one off for you guys Quote Link to comment Share on other sites More sharing options...
Ark Posted January 30, 2009 Author Share Posted January 30, 2009 That reads very much like "contrary to my earlier post, we don't actually have a Supra kit, off the shelf"... While I'm keen to see how this comes together, I'm still dubious about what is essentially going to be a custom build, due to the inevitable support issues that life's just too short for me to fuss with... Please tell me I'm wrong, and why. Quote Link to comment Share on other sites More sharing options...
rick001 Posted January 30, 2009 Share Posted January 30, 2009 Alcon have produced a big brake kit for years - obviously they wont/ carry stock if it has not been requested for a while which in this case they have not im told - but they do produce them and very quickly but, its a non stock item and to run just 1/2 kits would not be very viable so he is sorting out a costing for a run of 5 Quote Link to comment Share on other sites More sharing options...

Ark Posted February 4, 2009 Author Share Posted February 4, 2009 UK, CCX, DBA discs and fresh (changed regular too) dot 4 was great for me. Here's the thing - last time I bought DBA disks and Endless pads, it cost me nearly £800. Seriously, it's not a huge jump from that cost, to the price of a full kit...
