2371.0. "DEORE XT MTB BRAKE SETUP" by AIMHI::LARSON () Tue Aug 04 1992 16:18

    I have been wasting a lot of time recently trying to keep my Deore XT
    brakes in good working order.  Does anyone have any suggestions other
    than bring it to the local shop?
    
    The shoes are in good shape.  The problem is that there are so many
    adjustment points.  I don't know when to use which ones.  Is there a
    Shimano shop manual that may help me?
    
    I want to ride more than fix my MTB,

2371.1just move the pads in/outYNGSTR::BROWNTue Aug 04 1992 16:395
    I just move the pads in to the point where they best accomodate whatever
    action results from the brake lever's squeeze... sort of tuning up
    the entire system by just getting the last thing in the process to work
    right.  FWIW, I was told not to take XT Rapid Fire Plus brake levers
    apart.
2371.2how to do it (mostly)DNEAST::FIKE_MIKEWed Aug 05 1992 07:3429
    
    	I just upgraded my MTB Shimano 200GS brake levers to Deore, so I
    can tell you what works for me (may not be gospel according to
    Shimano).
    
    	You have basically 4 adjustments; a screw/cam device under the
    lever that controls the reach of the lever- adjust this one first with
    your cables loose to where the reach of the grip feels comfortable to
    you; the second one to do is the down cable that goes into the
    adjustment thingy that the cross cable (the one over the tire) hooks
    on. The third one is the cross cable and the last one is the fine
    tuning adjustment on the lever.
    	Do this- after you've adjusted the lever reach to where you want
    it. The cross cable should probably be o.k. where it is; screw the fine
    adjustments nuts all the way in on the levers (so you have maximum
    adjustment later so you don't have to make major ones so often). Then 
    hold the brake pads close to the rim (with your hand or a "third hand 
    tool"). loosen the adjustment nut and pull the cable tight and
    retighten the adjustment nut. Try the brake; adjust the fine tune until
    the wheel spins with no drag, but locks up with the lever pulled no 
    closer than 3/4" to the handlebar.
    
    	There are also pad adjustments which you can use to set the pads
    in/out up/down so they meet the rim and don't hit the tire. They also
    adjust the "toe-in" of the brakes so that the leading edge of the shoe
    touches the rim first (prevents squeaking brakes).
    
    	Richards Ultimate Bicycle book ($29.95) has a very good pictured
    section that shows all this in detail.
2371.3PIPPER::GOODWed Aug 05 1992 11:3714
    
    	There is another note on brake adjustment with good info on
    the pad adjustment.
    	I just finished building my MTB and I have the factory instructions
    on the brake installation and adjustment. There is a tool that is
    available. It is a bridge that holds the top of the cants so you can do
    the cable thing. Otherwise the previous reply and the other note are
    accurate.
    	One thing-the XT low profile compared to the regular is a much
    more elegant design. The pads are gimbaled and you squeeze them tight
    and sock them down and everything comes out perfect. The pads
    themselves have little posts that perform the toe-in automaticly.

2371.4ESKIMO::HUIWed Aug 05 1992 13:146
There is also another adjustmnt hex screw on one of the brake calipers. The hex
screw is to fine tune the brake calipers spring tension is equal. When you
squeeze the lever, both caliper should move, not just one.

2371.5Calaper mounting bracket holes adjust retract forceCOMET::PAPAVOTE LIBERTARIANSun Sep 06 1992 20:365
    In addition to .4 their are three holes for the retract spring on the
    mounting bracket for the calapers. Selecting one or the other of these
    holes changes the retract force on either calaper. In my case I have to
    have one set for more force then the other to get both sides to retract
    equally.
