Gubby, You must be riding pretty gently for them to only reach that sort of temp!! If they get too hot or can't dissapate heat fast enough, you'll get what is commonly called 'brake fade', but these Spyders have pretty damn good brakes, & you'd hafta be ryding them pretty hard to do that, cos it's getting up close to 'melt metal & boil brake fluid' temps!! (& your brake fluid will boil at a
whole lot higher temps than water!! :shocked: )
Put into simple terms, your brakes work by converting your speed into heat via friction thru the pads & discs, which then dissapate that heat fairly rapidly so you can contine to use the brakes to slow & to stop safely. If you ryde 'spiritedly', at times the discs on 'production bikes' will actually get to the 'glowing red' stage, which IIRC is pushing close to 600 degrees C. On race bikes with their hi-tech pad materials & on the track, their brake temps can easily reach 1400 deg C plus!! So your brakes are fine if you are talking 216 deg C, but they are barely working hard at all if you are talking 216 F!!
Still, if you feel the brakes aren't working properly, the very first thing you should do is go & get them checked!! Your brakes are just as important as your tires - between them, they keep you in contact with the ground & allow your Spyder to corner & stop safely, so you should
NEVER take chances with either!!
