But will the spool help in this probleme , because normally the spool is a locked diff so it souldn't help maybe im wrong , and could someone tell me when is the spool needed or the one-way .
Im not sure what you are referring to here but if its in reply to my post. There is NO setup change that will allow you to use brakes with a one-way (either front, center or both), unless you are talking about light drag brakes on the speedie.
Using a spool or diff with a fixed center pulley will allow you to use brakes if required. Most cyclone drivers seem to prefer the spool on asphalt unless the track is really tight and twisty. The spool has less initial turn in however this also makes the car more stable to drive. The spool has the advantage of allowing you to get on the throttle more aggressively when coming out of a corner.
