So me and a mate trimmed his Deore brake last night,problem is i think we lost a wee bit of fluid in the process,
One minute the brake works fine the next its lever to bars,is there a way to fix without bleed ie top up of mineral oil and tie lever back to extract any air or is it to late or that??
if its a bleed how much oil will be required??

    No...the air is almost certainly in the hose, filling up the resvoir doesn't get that out...

    Which Deore?

    If they sometimes work then you might get away with it, and there is nothing to lose by trying so leave the brakes with the lever as high as possible and no high-points on the hose and flick it to try and dislodge any air bubbles up to the lever then top off and strap as suggested.

    If it doesn't work you've not wasted much time or money and you're in the same place as you would be otherwise.

    If not, grab a bleed kit from epicbleedsolutions. It's a doddle!
