hard brakes on idle

hey there guys, ive recently got myself a k plate pulsar but its got a strange problem.
i bought the car knowing id have to change the servo but now im not so sure.when the car is idling the brake pedal is solid as if the servo has gone but when driving the brakes seam fine untill i dip the clutch and the revs return to idle and the brakes are solid again.
ive changed the fluid an cleaned all the callipers and all the pistons are moving freely. could this just be a low vacuum and if so what could be causing this. any help would be greatly appreciated as ive got a servo but i think its going to be a mammoth task to change. so if theres anything i can try first then i wildo.
thanks- Alan
