Just bought some new Formula RO’s and need to shorten one of the hoses so need to get some bits.
Anyone used the eBay bleed kits that are about £10? Is all Dot 4 the same? Any recommended brands?
Finally, do I need genuine Formula bits to replace the used fittings or can I use anything else?
Cheers

Support the North East and buy a kit from RedDogRacing:

hmmm, they dont seem to be showing the kits on their site. You should be ok without genuine formula bits from the various sites around. 🙂

RedDog don’t seem to have anything listed…

Dot4 isn’t all equal, it’s a vague recipe and a minimum dry and wet boiling point.

Typically 5.1 will have a higher wet boiling point, which makes it better suited to cars where the owners might not change it very often (should be every other year) but the additives that increase the wet boiling point suppress the dry boiling point, so if you bleed them regularly and they’re well sealed (compared to car/motor bike systems which are pretty much open to the air) then dot4 can be better.

Which is why some racing car/track day/kit car users still use stuff that meets the DOT 3 spec (but change it regularly).

But fort all practical mountainbike purposes, it makes no difference (when did you last actually boil the brakes (not expand the fluid pumping the lever out a bit, actually boil it so the fluid pisses out everywhere and the lever pulls to the bar).
