sticking back brake

[Decster]

The back brake seem a bit sticky, lots of dust on the wheel and when i let off on the throttle it is noticable how the bike slows. Checked the temp of the back disk compared to the front and was a lot warmer, but not burning to the touch.

Have not inspected yet.

What should i look for?

Worn pads

Sticking piston - apply copper grease...

TIA for any advice.

The rear disc will always be warmer than the front after a run, as some of the heat is transferred from the final drive.

Check that the caliper still has some float, I.e. rattles around a bit. If it doesn't, then something is sticking.
