Remember there should be a small clearance between the Booster rod and master cylinder and also between the brake pedal and booster. Bit of Plasticine on the end of the booster rod, fit up the master and then remove and see how far the Plasticine has crushed, will tell you the clearance.
Have also had Phenolic pistons that were tight in the callipers.
