Burning On The Back Of The Pads?

It says Brembo on the pad.

 

Looks like a rear pad?
If so, could it be dragging slightly and overheating?

 

Good suggestion - I once had the rear caliper on the Raptor burst into flames when the master cylinder seized and the brake was locked on.

 

Check callipers for sticking also slave and master cylinders?

 

If it's got that hot there should be signs of blueing on the disc surely?

 

It looks like caked on brake dust stuck in whatever grease (ceramic?) was applied

 

Cracking groovy discs, not a good sign.

 

As a matter of interest how thick (thin) is that disk? It looks to have quite a lip on its outer edge but that could just be the angle of the photo.

 

My 916 did the same, bike came to a gradual stop with the rear wheel locked up and the pads on fire.

Caliper appeared to be OK initially but a year or so later, it was found to be leaking.

 

About time it got changed then?
