Anyone else seeing this happen?

Drums and shoes were new in june 07, was off the road for three months over the winter, but was starting to before then.

just fitted new front brakes off a calibra with drilled and grooved discs, and it hasn't helped.

Any ideas?

If your car has been lowered then you may need to adjust your brake bias valve. It is attached by a spring to the rear beam and should be slack when there is no weight in the rear of the car. If the car is not lowered then it either needs adjusting for some reason or it has packed in. It many have got stuck so you could try a bit of WD40 on it to clean it up a bit for starters.

the bias valve should just be under tension when the car is on its wheels
