The wheel cylinders started seeping. I bought them about 4 years ago. Last year one was leaking and corroded some so I cleaned it up honed the cylinder and put it back together now they are both leaking. The truck sits inside for extended periods. I herd here on the forum that the napa wheel cylinders have steel pistons so I ordered 2 for the rear wheels only ,as I have discs on the front the numbers are 9375 and 9376 I got a discount through my repair shop that I rent out. They came today and I was hoping and took them apart and steel pistons not aluminum in both of them so now Im going to put a coating of red rubber grease in them and install them and the test of time will tell
