I will be following to see your conclusion on the front brakes sticking. I too have the Whitby brakes and the front stuck when I took it out. Still haven't found out why. But I have not taken it out again since. I was reading about maybe having to adjust the small screw plunger on the inside. Will let you know though for sure if I find the solution. Might try to get out and look at it this week. Been busy. 2 yr old boy will zap your wrench time lol
