New Wheel Cylinders, Different Internal Spring Pressure.

Two RockAuto replacement for 8 3/4”#2460668 originals from the rear of a ‘65 Chrysler.

There is a huge difference between internal spring strength. As seen in the picture the upper cylinder can be pressed in easily and the bottom spring pressure is almost pushing the pistons out of the rubber seals.

Another fact is that the top cylinder was difficult to push in, pistons dragging? The bottom was very easy.

Maybe just pull them apart for a visual?

Certainly I don’t want to start out with a problem.

Probably different vendors. All that spring does is keep the pistons and cups extended slightly and in place. I seriously doubt there could be and difference in performance between the two.

Who cares !!! Those springs aren't enough to push the shoes apart, they just keep tension on things.

That sounds reasonable and appreciate your quick response. I get worrisome when there is such a drastic difference.

Thank you too. Your direct response make me smile as though I’m the apprentice here and that’s correct!
