Bleed each brake and make sure the rears are adjusted well. All Dollys generally require more effort than moderns, braided broke hoses help.

thanks will try doing them this weekend, did notice that the brake pedal felt hard and suspect that there is no air in the system, could this be right, tractor boy

There is a standard test they do for brake servo operation on the MOT test.
Its runs along the lines of ..... with the engine off you put your foot on the brake pedal, with moderate pressure, and start the engine. You should feel the brake pedal sink slightly as the engine starts.
If the brake pedal feels firm ultimately, then it sounds as if the brake bleeding operation has worked O.K.
