kyepan 291 Posted May 11, 2006 (edited) So we can change to a pad which does handle that temp, if there is one I remember seeing a graph that says they operate best up to around 600-700 degrees and then their performance tails off rapidly. some other pad materials may operate a lot hotter. M1155 for instance, but you need to warm them up( as i found when i had them on the pulsar) though if you change pads, you may find the disc is too small to dissapate the extra heat generated, or the fluid boils, or the calipers arn't up to it. (what happened on my old pulsar.. great brakes for two or three applications, then pedal to the floor pant wetting time) It might be worth looking into bigger discs, decent fluid and some better twin pot calipers. before you change the pads.

Rippthrough 98 Posted May 11, 2006 When braking the very top layer of the pad material is turned straight to a gas, the process involves that much heat , so technically your burning away your pads all the time.. i think this is why we have grooved and drilled discs.. to expell the gas. But to answer your question, I remember seeing a graph that says they operate best up to around 600-700 degrees and then their performance tails off rapidly. some other pad materials may operate a lot hotter. M1155 for instance, but you need to warm them up( as i found when i had them on the pulsar) At the moment the weak link in the chain appears to be your pads, if you change them you may find the disc is too small to dissapate the extra heat generated, or the fluid boils, or the calipers arn't up to it. (what happened on the pulsar.. great brakes for two or three applications, then pedal to the floor pant wetting time) It might be worth looking into bigger discs, decent fluid and some better twin pot calipers. before you change the pads. It's for an autocross type buggy which can only fit solid discs, although he can go a bit thicker to absorb more heat, hence the need for better pads. They've been Ok for a while but he's starting to use the brakes much harder now. They were suffering badly from fade, must have been 700+ then Share this post Link to post Share on other sites
mfield 20 Posted May 11, 2006 Doesn't rallydesigns cat' have the temps of all types of pads ? Share this post Link to post Share on other sites
Rippthrough 98 Posted May 11, 2006 (edited) Doesn't rallydesigns cat' have the temps of all types of pads ? No idea, I don't have one Trying to see if the 307 brakes will fit in the space he has, hence the plea for measurements in the other thread Edited May 11, 2006 by Rippthrough Share this post Link to post Share on other sites

jonah 1 Posted May 12, 2006 Rally Design only sell 1144's. Miles is a Mintex dealer though so should be able to get you 1155 / 1166 pads. Haven't tried 1166 but have got 1155 at the mo, they are absolutely fine from cold. Share this post Link to post Share on other sites

Trying to see if we can rejig things for vened discs atm. Share this post Link to post Share on other sites
