The reason I'm asking is I replaced the rear wheel cylinders and shoes but as soon as I secure the 2 screws, the wheel binds turning backwards on the drivers side. Turns forward fine. Any idea why the screws would cause this problem since it doesn't occur when they are not tightened. Got me stumped. | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy ff171, I assume the two screws are holding the brake drum to the hub, when you tighten up the screws you bring the brake drum up tight against the hub, duplicating what the wheel and wheel nuts would do. So if you are experiencing a rub there may be a burr on the outside of the hub or the inside of the drum, maybe an errant piece of gasket material. If you can turn the wheel by hand in either direction when the screws are tight I wouldn't worry about it too much. Have you adjusted the brakes yet? | | | | | Joined: Apr 2014 Posts: 33 Wrench Fetcher | | Wrench Fetcher Joined: Apr 2014 Posts: 33 | Thanks 3B, I did adjust the brakes and can turn the drum forward by hand but not backward when the screws are tightened and just on the left side. Just wondering why the screws would affect anything but I will check to see if there is something on the backing plate catching when moving backward. | | |
