Hi there

I have a slight problem and am not sure what to do.

I have avid juicy 3 brakes and the rear brake lever has completely gone soft and there is no braking power. I did notice at the back where the brake system is is some clear liquid had leaked from the drum (not sure what to call it) Seems the two nuts were slightly lose so I presume brake fluid had leaked out. How do I fix this?

Thanks

Michael

    tighten it all up. and get the system bled.

    sounds like someone has been undoing bolts that should not be undone. there is a good chance that new pads will also be needed.

    If fluid has leaked out, there will now be air in the system, so it needs a bleed.

    DOT brake fluid is nasty stuff & makes a fantastic paint stripper. Be sure to douse anywhere that fluid has leaked onto with plenty of water ASAP to limit the damage.

    I had the same problem with mine.
    When I was out biking, the lever would fade after braking for a long time and then go harder once everything had cooled down.
    The fluid was leaking from lever area and paint had bubbled.
    Tightened the screws and got the brakes bled.
    Ok now.
