Is Uppers Aced not working

The actual effect of the skill is:

If a drill breaks down it has a 30% chance to automatically restart after a few seconds.

The main issue with this is that you will in most cases run to the drill and start repairing it anyway, before you know if the auto-repair triggers.

The inspire ability has a 100% chance to revive your teammate by shouting at them (20 second cooldown). You can revive through walls and floors by looking at them and shouting. I believe the range that this works over is tied into the range of your shout ability (which can be increased with the Mastermind third tier bonus).

The speed is faster than the usual method of reviving as shouting is an instant ability, when inspire procs your target will get up immediately. However, due to the way ranged targeting works in Payday 2, in the event there is another player (or enemies, if you're in line of sight) near the player that is downed it can be difficult to target the correct player.
