That is the question....I've had to use the cube tool before and they always slip so it was recommended to me to use this kit which worked like a charm. Any opinions on using this instead of the cube:

Pneumatic 11-Piece Caliper and Brake Service Tool Kit -

 

By all means use the kit. Free loaner at any BIG box auto part store, just need a refundable deposit.

 

Use it and love it. After you use it you will wonder why you even ever used the cube. Your knuckles will thank you. Thats the exact kit I have and I will never use the cube again.
