dot 4 or dot 5
time to change and dont know what to go with?
any sug.

dot4 is more than good enough, and cheaper than dot5... plus it's easier to find

[ssg]

dot4 unless you're gonna bleed the system and drain it extensively before going to 5, or your bike came with it

I say this only because one of the guys I ride with hates dot5 mabey he had issuses useing it but he told me that dot5 is harsh on rotors. (?) I didnt get it ether. anyway I use it (dot5) and never had a problem. I told him to change his pads more often.

I hear there's DOT 5.1 that isn't silcon based? (whatever base) like the 5.0 but has the same characteristics. DOT 4 is more than good enough.

I would definately trust this guy's judgement He sounds very knowledgable

[OreoGaborio]

yeah, 5.1 is silicon based, but 5.0 is sand based... it seeps through the caliper piston, through the pad & grinds away at your rotors






what a goon

Dot 3, 4, and 5.1 are glycol based and Dot 5 is silicon based. Do not mix the two. Glycol based are hygroscopic (absorb moisture) while silicon based does not, however, the o-rings and gaskets used on each may not be compatible with the other.
