RE: [ST] Front Brake tweak......

["colt4530@xxxxxxxxxxx" <colt4530@xxxxxxxxxxx>]

I did it when I had my front tire replaced.

I sprayed the calipers and pistons with brake cleaner, just a quick spray
off.  Then I pushed the pistons all of the way back into the calipers
(gently, now) to make putting the wheel on easier.

With the wheel back on pump up the brakes; it takes several strokes (15?). 
That's it!  Ther is no trick really.  It appears the seals are made to
retract the pistons slightly for less parasitic drag.  Pumping them out
hard against the disc doesn't leave room for the retraction, until the pad
wears, anyway.  

The cleaner spray was not part of the solution, really.  I did it so I
wouldn't risk pushing dirt through the seal into the caliper.  Dirt and
brake dust cannot prevent the pistons from moving OUT because that part of
the piston is clean and protected inside the caliper.

Hi All,

Awhile back there was some talk of a very minor but very effective tweak
that made the front brake lever feel much firmer, or reduced play, or
something. My bike has all kinds of stopping power, but I can squeeze the
lever nearly to the grip, so I am guessing she is a candidate for this. It
involved cleaning and relocating the O-rings on the calipers, or something
like that. The front wheel is off getting a new tire, I figured now would
be the time to get in there. 

Can someone refresh my memory as to what needs done, or just resend the
email if anyone still has it?

Thanks,

John
