Hi Justin,

I’ve always found it pretty straightforward – usual risk of bleed nipples snapping or rounding off – splash some WD40 around a day or two before and use a good fitting wrench is advice I have wished I had followed.

I have never had a problem getting a decently firm pedal so I don’t think there’s a special knack required.

As for the fluid – DOT 4 is fine assuming you have not already got silicon (DOT 5) fluid in the system. Both fluids look the same when new.  They don’t feel the same on your fingers but that’s not a great way to distinguish them. The two don’t mix well so, if you don’t know what you’ve got in there, whichever one you choose, you should probably plan to flush the whole system through – which probably means doing it twice.

That’s just my view.

Chris
