I had just posted that I was having trouble with my rear right side wheel dragging. It was the wheel cylinder on one side froze up. Got that fixed. I have had the trike for a little over two years. I had bought some super beetle wheel cylinders right after I got the trike but never put them on but they are for the rear. It doesn't look like they would fit. The bleeder valve is not on the top of the cylinder.. Can someone tell me which cylinders I would need and what all I would have to do. I would like to up grade. Do you still use the stock master cylinder? Thanks
