If you don't mind going old school look at the Tektro CR720 cantilever brakes.
I recently changed my Atlantis over to these because the bridal cable on the
Suntour XC Pros didn't really clear the fenders with a good line and will never
clear the Nitto mini rack I plan to install. So far I am happy with these
brakes.
I also had a squeal issue with my Quickbeam and tried several brakes and pads
with no luck. I installed a set of these in the front and no more squeal.

Subject: [RBW] Re: Tuning Brake Squeal
A timely topic for discussion, this is. I've recently encountered the same
problem on one of my bikes. It is a Surly 1x1 and for years I've had a problem
mounting a rear fender because the arms on the run-of-the-mill Shimano linear
pull brake aren't long enough to accommodate both a fender and a 60mm Schwalbe
"balloon" tire. So last Winter I decided to do something about it and got
ahold of a Tektro 857AL brake with 110mm arms, long enough to clear the tire
and fender. The set up worked out very well - clearance is great. The actual
application, not so much. After a few weeks of riding, a tremendous squeal
started from the rear brake (the front has a disc). Now, these particular
Tektros are very cheap brakes, apparently made for low-end bikes, so I notice
quite a bit of play in the arms at the point where they bolt onto the seat stay
mounts. That's what I'm blaming for the squealing - an oscillation caused by a
tiny back and forth movement of the arms as the pads grip the rims while
braking. I plan to get some thin washers to place under the arm pivots to see
if I can take up some of the slack. 'Course, I could be wrong. As someone
else on this thread mentioned, the longer Kool Stop pads may be part of the
problem, too. So that'll be step 2 if this solution doesn't work.

Batman! What causes different pitches in brake squeal? (I got to thinking
about this given the bell thread.) Here are the instruments:
Bike one: Pitch is a high D. Quickbeam with 700c Araya TX310F rims, Shimano
cantilever brakes with koolstop pads (model unknown; whatever cam stock on a
QB),
Shimano Tiagra Road Brake Levers, and panaracer paselas.
Bike two: Pitch is a low E (yes, almost an octave between the two bikes).
Custom with 26" Aeroheat rims, Paul Touring canti's with koolstop pads, Shimano
MTB silver brake levers, and Big Bens.
Let the theories commence!
Inquiringly yours,

PS. They sound like a great two-tone car horn when braking simultaneously.
