nope just nose pliers to unclip the lower spring and remove the spring loaded caps holding the shoes to the backing plate, then you try to unhook the bottom of the shoe from the ledge with ya hand to release it. taking out the hub with a 30 or 27mm socket & breaker bar makes access much easier
much much easyer having access it always is but could it be done with a bit(lots) of difculty without removing the hub nut?
