Well no Rick, if they pull up steadily then that means that your Drums are as they should be ROUND!

The fluid doesn't have to be compressed, the only reason the pedal pulses when the rear drums are Ovaled is because the Fluid is acting like a solid object when you compress it, so when the wheel cylinder is pushed back in because of the Ovaled drum, the fluid has to go somewhere and your foot is weaker than the Solid drum!
