dixi188Four wheel bogie landing gear.
I expect the forward tyres would get hotter due to the load transferring to them during braking and the greater deflection caused.


Possibly. The brake equaliser bars are designed exactly for the purpose of distributing the load in a more equal fashion between the forward and rear axles. If the brakes were mounted rigidly to the axle, the reaction to the braking moment from the front axle brake packs would tend to put a much higher load on the front axle wheels.

The geometry of the equaliser system is such that the brake torque from the individual brake packs tends to lift the front axle off the tarmac whilst forcing the rear axle down harder. This mechanism distributes the load in the landing gear strut in a much more equal fashion between the axles, and makes the rear brakes do their equal share of the retardation duties.
