T100 Scrambler

Got another question. My 900 Scrambler rear brake. Checked tonight. Every thing is free and movement as usual good pads. But the disc looks like it is overheating has all the burn look around the disc center and outer edge. Is it a warped disc. I did look at it and spin the rear wheel and it looks quite true Alought to the naked eye it might be hard to see. Any thoughts.

 

@Mark TGR9 Yes that is what baffles me. I only ever use the back brake in the rain.

 

@Mark TGR9 You know i have had this on my mind all night. And you have to be right i must be riding the year brake pedal only explanation and riding is not braking. Going for a ride today to see if i am the culprit. Thanks for the good suggestion

 

@Mark TGR9 Yes i think you had a good point there. Rode eighty odd miles and it seems fine. Found my food was just touching the pedal so repositioned it. Would like to adjust the brake lever but don't think they are adjustable.
