Nick Posted June 11, 2003 Share Posted June 11, 2003 I´ve decided not to risk the AP´s as I can´t be certain they´ll fit within the Blitz rims. Decision now is whether to buy a set of Brembo´s or to go for UK Specs. Has anyone upgraded from UK Spec to the Brembo kit? Is there a significant difference between the two to justify the money?? Thanks in advance.... Link to comment Share on other sites More sharing options...
Guest Terry S Posted June 11, 2003 Share Posted June 11, 2003 Nick I honestly doubt they will stop you any quicker than UK's. The only advantage I can see is for repeated high speed stops & track work due to heat dissapation. Look nice though;) Link to comment Share on other sites More sharing options...
Terminator Posted June 11, 2003 Share Posted June 11, 2003 I am sure Martin will be along, to confirm, but he did some calculations on the piston area and the stopping power of the six pots over the stock four pots was about equal. The only gain would be if you could get larger diameter rotors under your wheels then the distance from the centre of rotation of the applied force would be greater and therefore stopping power would increase. As said before there would be a slight advantage in heat dissipation at the limits with the six pots. Link to comment Share on other sites More sharing options...
Guest Martin F Posted June 11, 2003 Share Posted June 11, 2003 I'm not sure if it was me, but i remember the discussion and i concur. The advantage of the six pots over the UK brakes was minimal. Link to comment Share on other sites More sharing options...
Gaz Walker Posted June 11, 2003 Share Posted June 11, 2003 Theres a comparison on SF that I remember reading a while back. The conclusion was that the stock brakes will stop quicker than the brembos in all applications, its just that the Brembo's will hold up to sustained track abuse for longer... Gaz.

Terminator Posted June 11, 2003 Share Posted June 11, 2003 I love the way the stock UK brakes stop the car, 70+ to 0 is awesome you just have to be careful who is behind:eek: I have not come across anything yet that I can not out brake on the road.

Yep, its still the best braking car in the US I think so its gotta be one of the best here too. Its braking performance is better than the 911 turbo which is widely regarded as one of the best stoppers going. I only stopped from 30mph in 4/5 metres dead. It really hurt(!) but it would have hurt more if I ploughed into the tosser that pulled out in front of me! Gaz. Link to comment Share on other sites More sharing options...
Doughie Posted June 11, 2003 Share Posted June 11, 2003 At the end of the day, the limit to the "stopping power" will be the friction of the tyres on the road. if your brakes can activate the ABS system, then that's as fast as the car can stop. Where extra big brakes will help is, as someone else said before, is potentially on a track where the heat dissipation may be better and therefore it's more of an issue of the brakes SURVIVING rather than them being able to stop you any quicker. Also, some brakes may *feel* like they're stopping you quicker because they need less pedal pressure to do so, or the pads are very aggressive and give big initial bite. all of these things will make the brakes feel more powerful, but ultimately when you really stand on them, i doubrt they'd bring the car to a halt any faster than UK-setup. just my 2p Link to comment Share on other sites More sharing options...
Guest Usmann A Posted June 11, 2003 Share Posted June 11, 2003 Im not clued up on most things, buts everybody seems to say the UK spec brakes are good, and are close to AP/Brembo. But, we have had AP 4 Pot 325mm discs, and the UK spec brakes cannot compare. As from my dads view, the AP far exceed th UK's, im not intent on starting a big row over this, but it seems they are hyped a bit, they are no-way near AP/Brembo brakes. I have no solid evidence, but my dad drives both cars and says AP are miles better, I can even feel it from the passengers seat, they is much difference. I mean AP's seem to have a bad theme around them, but Brembo are supposidley better, so the UK specs are out of their league, being compared to them. Before anyone suggest that they are track use, but in a high performance car, you are definatley nail it at some point, even in situations which you may think are safe but, later on realise the stupidity/risks of your actions. Thus, best brakes for the road should be put on, as we all know safety is key, and nothing can compare to race bred/rigerously tested parts which can help you reach your target faster= safer, also withstand the abuse..(race technology) This is just merely our conclusion after having UK's on the soop, and AP's on the saab, after a year and the UK's cannot stop within the distance AP's can. and the saab weighs 1700 kg! If anyone knows some valuable info, which could be of use I love to know. Link to comment Share on other sites More sharing options...
Guest Usmann A Posted June 11, 2003 Share Posted June 11, 2003 Im not saying toyota R&D did not do a good job, but items from AP, ok forget AP...........Brembo are miles better. I mean our experience, shows that with the AP's you can brake so much later, ie keeping it going faster,longer. Ok, were not silly ricers, but as we purchase cars like this, and therefore expect good response performance from our cars on the road, we intend for them to deliver it all the time, and prefrom thier to thier best safely....to a certain degree, when requested to do so.

Alex Posted June 11, 2003 Share Posted June 11, 2003 Look at the table here... http://planetsoarer.com/suprabrakesII/SupraBrakeUpgrade.htm See where the UK brake is compared to the AP/Brembo in an independant test. This is on a 1 stop max braking effort. With the use of decent discs and pads the UK brakes WILL stop first time harder than the AP's/Brembo's. However I have no data for multiple stops. But look at it this way. You can't really go wrong with the UK/AP or Brembo options but 6-800 for the UK's is phenominal value for money when the AP'and Brembo's are twice that and the cost of replacement discs and pads is also probably higher too....

Guest Usmann A Posted June 11, 2003 Share Posted June 11, 2003 Hiya Gordon, Im not just saying this from myth, Ive personally experienced it, when slammed the AP make you feel sick, and can stop from 100+ speeds far quicker than the UK's. I mean, my dad nearly hit the supra a few times,after fitting uk's, as he was expecting AP stopping perfromance from them, which they cannot deliver. Im not saying, race cars parts for road cars,but generally if parts can withstand the abuse of the track, and perfrom good. Then they in most cases work great for the road....in this instance brakes...not including racing dog boxes, and flywheels.... Link to comment Share on other sites More sharing options...

Guest Usmann A Posted June 11, 2003 Share Posted June 11, 2003 Yes Alex, interesting read, buunfortunatly doesnt convince me, oh and the cost factor, they APs were 1500 quid. All in all, not very happy with the UKs might put on a set of Brembo's. Link to comment Share on other sites More sharing options...

Guest Usmann A Posted June 11, 2003 Share Posted June 11, 2003 Sorry Gordon, didnt quite make it clear, what I mean was that lately there has been bad news with AP, soin most eyes,they are not the best. But brembos are one of the best at the moment, thus my arguement showing that AP are beter UKs, meaing UKS shouldnt e compared with Brembos.....if that makes any sense...

Gordon F Posted June 11, 2003 Share Posted June 11, 2003 Ali Believe me - materials used for race car brakes are totally useless for road car application. Dont forget, race car brakes work within a temperature parameter - you can never do this with road cars. Dog boxes for the road?? I thought the MK 4 manual was clunky enough - that's why I bought an auto Link to comment Share on other sites More sharing options...

I was starting to wonder that....probably cooked the brake fluid and or glazed the pads...or used the wrong fluid. What colour are the discs what pads are being used, how long since a change of fluid what type is it? Link to comment Share on other sites More sharing options...
Guest Usmann A Posted June 11, 2003 Share Posted June 11, 2003 Alex mate, deal! But where would we do this....??? Steve, good you mentioned that steve, as their is alot of play in the pedal, the fluid has been changed a week ago. Link to comment Share on other sites More sharing options...

Do you mean there is a lot of play AFTER you changed fluid, or there WAS before or there WAS and IS still play. There should be a good hard controlable bite. Does the pedal sink during braking, is there little bite, do they stop straight, can you get the ABS to kick in at speed, what tyres have you got.
