A tension control assembly including a rotating member (14), a braking member (28), at least one brake pad (30a,30b,30c,30d), a means for driving the at least one brake pad (30a,30b,30c,30d) against the braking member (28), and a temperature sensing means. The braking member (28) is attached to the rotating member. The at least one brake pad (30a,30b,30c,30d) is positioned adjacent to the braking member (28). The means for driving the at least one brake pad (30a,30b,30c,30d) against the braking member (28) forces frictional contact between the at least one brake pad (30a,30b,30c,30d) and the braking member (28), thus providing torque to the rotating member (14). The temperature sensing means measures the temperature of the at least one brake pad.
