Mustafa, I asked all those questions not to disuade you, but for some answers fro myself as well, from someone who might have them. I have switched the rears to the newer ones, but I do not have an E-brake hooked up. The brakes work, but I do not think as were designed to, nor as well as they should. After all, the leading and trailing shoes are not in the same (9 o'clock & 3 o'clock) positions as the original set-up! They now sit closer to 8 & 2.
