Default Odd remark from a mechanic at LBS

while having the brakes checked, rim cleaned at the local LBS
the mechanic referred to the mavic open pro in front as the "disk
brake rim"

(I don't see CD markings anywhere so go to assume mine is not a
ceramic, but a lesser version)

what the heck did he mean by "disk brake" for what i understand is
designed as a road going rim?

the rim is uniform green or gray all the way on the outside with no
bare metal exposed
as on cxp-33.

You have the Ceramic 2 or CD treatment and not the usual "UB Control"
shiney brake tracks, so the guy is probably confused. AFAIK, the Open
Pro does not come in a disk only model. -- Jay Beattie.

Thanks Jay!

I think I'm running cantilever pads while I have v-brakes

could this be why salmon koolstops squeal so bad after a short initial
bite?

Your brakes squeal because you are using Koolstop pads. Koolstop pads
SQUEAL.

None of mine do.

Some brakes on some pivots are chronically likely to squeal regardless
of setup. Short, loose-fitting bushings and cantilver brake arms that
flex between pivot and pad are reliably loud features. Such brakes
squeal more loudly or more often when fitted with pads that have a
high friction coefficient, like Kool Stop red oxide pads.

High friction coefficient isn't really a fault of brake pads.

Some brakes can be rendered quiet through the use of sorrier pads, in
the same way that almost all brakes can be made silent by
disconnecting the actuating cable.

SQUEAL.


Please don't let any of the many thousands of squeal-free bikes I've
installed Koolstop brake shoes on know that! Seriously, Koolstops are
the go-to brake shoes for bikes with issues, including squealing. There
are some cases where even a Koolstop won't render a brake squeal-free,
but I haven't found other pads more likely to.

Th pads are working, the mechanism is working, it's the rim that's
loose. Better wheel contructional techniques eliminate "brake squeal"
every time. Get them tied and soldered.

CD is something like 'couche dure' (?) or whatever :-) - it's what
they call the coating treatment - no ceramic required, I think.

I have an old mavic rim like that - with the gray/green/brown shiny
coating. You can stop the bike fine even with the shiny coating, but
the coating wore right off what with all the rain and sediment around
here, and now it brakes like any other rim.

It's very pretty.
