?? seems a little drastic to change to drums....lol

I had a similar problem, turned out to be wheel bearings, was on a Saxo but it felt like the brakes were binding- may be worth checking.

Brake pedal not allowing mastecylnder piston to coming back far enough ?

Also make sure the resevoir isn't over filled.
