help please - caliper rebuild

Hi,



I am in the middle of rebuilding my front calipers and it is near impossible to slide the piston back into the caliper. Is there a trick to doing this?



Also, what's the best way to attach the dust cover to the caliper once it's already been attached to the piston? There doesn't seem to be much clearance to work it in there once the piston is partially in the caliper.



Thanks so much!
