burntread Posted January 18, 2010 Share Posted January 18, 2010 I just received the Rear Disc Brake Conversion kit from M-M and picked up a set of rebuilt 240SX calipers. Now, I'm trying put it all together and mount the things, but I'm having a bitch of a time trying to get the pads far apart enough to slide them down onto the rotor. I've tried to depress the piston for more clearance, but it seems like that isn't the problem. It looks like the part of the caliper that moves (the bar with the bushings that mounts to the caliper body) isn't moving enough to give me the clearance I need. I'm basically looking for suggestions. Thanks guys! Quote Link to comment Share on other sites More sharing options...
h4nsm0l3m4n Posted January 18, 2010 Share Posted January 18, 2010 I think the caliper piston twists itself out to compensate for thinner and thinner pads. It needs to be retracted by simply rotating it with a pair of pliers until you are able to slip the new pads in place. Here is a picture for reference (source: http://forums.nicoclub.com/zerothread/248077) Quote Link to comment Share on other sites More sharing options...
burntread Posted January 18, 2010 Author Share Posted January 18, 2010 Cool! I will give that a try. Thanks! Quote Link to comment Share on other sites More sharing options...
ktm Posted January 18, 2010 Share Posted January 18, 2010 Stepan is correct. The piston must be rotated in and out. It can take quite a while to get the clearance you need, so be patient. Quote Link to comment Share on other sites More sharing options...
burntread Posted January 18, 2010 Author Share Posted January 18, 2010 Yeah, I tried it on one side and messed with the little rubber bushings, as well. I put the pads back in and the caliper slipped right onto the rotor! Great advice! Thanks! Quote Link to comment Share on other sites More sharing options...
