brakes going mushy and getting very hot??

[White Rad]

last few rides noticed my brakes getting very mushy to the point the lever comes almost to the bars. I've bled them and there is no air so i think its more that they are getting hot. my concern is how hot they are getting only coming down from a few big pulls before letting everything cool and i always keep the clutches engaged and pulse the brakes coming down. the rotor almost looks blue and glazed and the spanner nut that holds the rotor has had all the gold colored coating baked right off. pads looks like they have plenty left. could it be a bearings behind the rotor gone out transfering extra heat to the rotor and track shaft?

maybe

maybe it is the brake bearings, because i ride the hell out of mine and never seem to get hot or wear down, overr 5000 miles on set now...

moisture in brake fluid brakes get hot water boils and you get fade install some racing brake fluid most bike shops carry this and it should fix it for you

My friends m7 on the first ride this season he made it about a mile up the rode
and noticed his brakes were not working they completly faded out,so he stopped to check it out but his brake rotor was dang near glowing red but yet when he started riding that day It didint feel likje the brake was on at all?we let it cool down and looked it over to see why it did that but we could not find a single prob with it.After that we rode all day with no prob.

Does your brakes only fade out after you use them alot or a little or do you get brake fade even when you ride down the road.The only thing I can think of would either be a bad bearing or a problem with the brake caliper itself.

have you messed with the brake handle at all? if they get tightened a little too much they can hold the master cylinder piston in just enough to cause the brakes to drag lightly..which will overheat the pads, rotor and caliper...and boil the fluid causing a soft handle....your handle when all the way released should have just the slightest slop before it applies the piston in the master cylinder...easy to telll.go for a 100 ft ride and see how hot the rotor/caliper is..if its hot at all its dragging...

If you set the parking brake when you trailer it, check the pin that holds the brake pads in, there is a hairpin clip that will turn sideways and put pressure on the pads and rotor.

well i figured it out we just needed more snow. it was so deep this weekend didn't need any brakes as we were getting stuck going down hill. actually i ended up tearing it all down and bearings were on the way out so i replaced them (which i wanted to do anyways in case they had anything to do with my 3 blown d drives). also bled the system again and now everything is working perfect.
