Staying with Caterham, for Monaco & Monza, in Monaco the brake_bias is bit smaller (0.574468 vs. 0.576923) and the brake_torque_forward is 2350 vs. Monza's 2600. And quick look at Hockenheim, Korea & Sepang reveals, they are the same as for Monza. And these values seems to be the same for McLaren too in other tracks except Monaco.
