sounds like your having fun.

make sure all of the old grease is removed from the bearings and they rotor hub. if different flavors of bearing grease(s) are mixed, the mixture will either harden or go liquid.

lesly tools makes a great bearing packer, but doing it with your palm is sufficient.

i believe each bearing takes 60cc's of green snot. no more. no less. that amount lets the grease flow when its up to the proper temperature.

if a caliper was hanging up and the caliper looks good, it would be wise to replace the hoses. they could be delaminating internaly.

you said that your pushed for time, but never rush a brake job. i like to replace everything from the master to the pads, so there is no doubt. ( i stood with all my weight on the pedal after a brake job on a 67 chevy. it held firm and then blew a hard line 3 miles later comming off ski mountain road. )

don't let the wife or kids drive it until you are satisfied that everything is up to snuff.
