i bought your conversion brackets some time ago and finally got around to converting my rear drums to discs / Wilwood Dynalites. when i test drove the car, there was an issue with brake dragging especially after the system warmed up a bit.
i checked everything out and the calipers / brakets are all square and mounted correctly. i bled the system 4 times and it runs solid. what i did notice was that the rear calipers didn't have as much pressure as the fronts when i bled them.
since this was originally a disc FR / drum RR combo, do you know if the stock Datsun distribution block has some sort of a metering valve to limit the pressure going to the rear lines? and if so, could i compensate with a proportioning valve to adjust for more rear bias?
