A while back, I think it was Dennis Haynes who mentioned the difference between OEM rear
wheel cylinders with a spring to eliminate the need for pumping (or something like that). Now
I want to do my rear brakes and I can't find the post...

My brakes were done at the dealer around 100k kms ago (11 years ago!), with new drums
and wheels cylinders (by the PO), so I assume they used OEM cylinders, but I do seem to
have the pedal bleed down issue, where I need to pump the pedal once or twice to get a solid
feel. Front brakes have new pads, calipers, and machined rotors, and all fluid has been
flushed every 2 years. The pedal issue has been constant for many years, as long as I can
remember.

I would rather do the rear brakes now, and not look at them again for another 10 years (aside
from fluid changes). So which wheel cylinders do I get for the oem performance? I'm puzzled
as to why my dealer serviced brakes have always had this issue, unless the dealer didn't use
OEM parts, or I have some other issue with similar symptoms.
