Re: [ST] st Digest, Vol 9, Issue 41

 I've just got back from a few days away and I'm just catching up on my 150+ emails, so my apologies if this has been answered on this thread.
 
What do you clean the brake caliper pistons with? 
Is it the brake cleaner that has been mentioned already or is it just a matter of blowing/wiping the grunge off? 
Am I right in reading that no lubrication is applied to the pistons once they are cleaned?
 
Thanks in advance,
 
Brett.

On my ST I regularly do the brake clean that everyone is talking about
(calipers off, hold 1 or 2 pistons and slowly pump brake lever to move the
remaining pistons, clean and push back in, repeat) and it really works.  I
also have a S3 to which the PO fitted a bigger Brembo MC - the difference,
on what amounts to very similar brakes on the 2 bikes, I believe,  is
simply breathtaking.  I never really have to clean the brakes on my S3 and
they are still better than the brakes on my ST - even after just cleaning
them. 

The bigger MC certainly seems the way to go...it doesn't hurt that the
Brembo MC is gold and looks rather nice :)

I have found that if you exercise the pistons without even cleaning them
the brakes feel better for a long time.  Mine are just getting the "long
travel" syndrome and it's been over a year since I exercised them.  I'm
going to do something with the brakes during the off season.  A good clean
job is the cheapest thing I can do that actually shows up on the road.
I've been kicking around getting that SkyKing MC/extra line kit, but I
know it is tossing bucks down the sewer. My rationale is that $140 spread
over four months of reduced ride time isn't all that expensive and the
brakes will bleed easier.  I've had a couple of guys who really know what
they are talking about (one works for Carbonne Lorraine) tell me that a
larger M/C and possibly the second line helps to keep the pistons from
sticking, but it is the sticking pistons that are the true source of long
lever travel. Rod _______________________________________________
