What is the brake torque and the needed force to stop the drum.

Data not on photo: Max pressure is 0.7MPa and friction coefficient is 0.2.
Homework Equations
T=(P1-P2)D/2
p=2P/bD
dP-fdN=0
dN=Pdθ
The Attempt at a Solution
The only thing I've been able to do is use p=2P/bD and rearange it to get F=8.68N
I am unsure of what dθ is supposed to be since the band lifts up on a portion of the drum.
