I'm looking for a pair of the old quick release cams for the old cheap Weinman side pulls. It's a round chrome pin that screws into the arm of the caliper where the barrel adjuster normally clamps through, with a flat thumb actuated cam plate that slides over it, and has a barrel adjuster in a sleeve that stops against the cam plate, a simple design, but effective.
If you have any in a parts bin that you don't need, please contact me off list. Even one will allow removing at least the front wheel without having to unscrew a brake pad. This is for my wife's Jack Taylor ladies project bike that I'll be bringing to Cirque.
