There is an updated backing plate to replace that trouble-prone design that you still have. It requires the use of a normal bolt-on wheel cylinder. Be sure to check the diameter printed on the lip seals so you get the correct size.

If the lock ring is not biting, you likely don't have it fully installed. That clip can be very difficult to lock in. I usually wedge something steel between the wheel cylinder and the wheel hub to hold it tight against the backing plate while using a punch and hammer in the rear to get it locked in.
