Hello again if i use treccia metallica in the front brake i will improve the braking? it will break faster? ::)
			
			
			
				yes sure... much faster response...and much harder than stock tube when the temperature of the idraulic liquid rising high.
but don't thrust to have a radial pump with only a tube changing...
a brake line is only a tube, not a pump and not a brand new 4p caliper..  ;)
			
			
			
				the mod yuou're talking about is actually  a major improvment, it makes the inner expansion colse to zero, so you have a better performance and a superior feeling, it's also a quite cheap mod...and it looks trick!
