"I needed to replace a leaking rear brake cylinder. I've always had a problem with keeping all the parts aligned while I install the brake shoes, particularly the snail cam sub-assembly which slides easily out of position. It occurred to me that a strong magnet as shown in the attached picture would eliminate that variable. Tried it and it worked very well. Got everything in place and secured in record time. Don't forget to remove the magnet before you button it up".
