Broken Brake Cable Clamp

I have a older Weinmann 500 side-pull brake set. When installing new cables last night, I was torqueing the cable clamp screw down, and snapped the thing in half. Is this a type of item that a LBS would have in stock, and are these parts fairly universal among side-pull brake sets? Or am I out of luck, and in need of a whole new brake set?

Also, for future not breaking things purposes, is there a torque spec on such items?

Side pull anchor bolts used to be a very common LBS stocked item. less so these days. There are two common sizes and a few variations of shape/flats on these. Bring in the caliper to insure proper fit of the replacement. Andy.

Agree with Andrew, above. And keep in mind that a suitable replacement might be found on another brand of caliper, e.g. Dia-Compe (licensed copy of the Weinmann caliper) or even other brands, which might be found in the used parts bin of your LBS or bike co-op.

Take the unbroken bolt from the other brake to the LBS so they can match a whole one. If they have two, replace both, keepping the old one for a spare. The older the bike shop the better chance of an exact match.
As for torque specs, google 'bike torque specs'. Of course you need a torque wrench to apply the specified torque.
Or just get them RT(Real Tight), which is more then T(Tight) and less then RFT(Real F*****G Tight)

Ha, that was originally my intention (and realistically, how I tighten everything that isn't located in an internal combustion engine). I wasn't much past what I thought of as T, though, which was about a half turn past finger tight, when it sheared itself in half!

The "thing" is the anchor bolt, now that Andrew has update my knowledge of technical terms. Sheared in half.

I'll give the LBSs a try at lunch. Just panicking about potential local availability, was hoping to take it on an extended (to me) ride this afternoon that I really didn't want to use the mountain bike for.

There are ways to hack a repair. Use any small bolt, with a split washer and nut to trap the cable between hanger and nut. It isn't ideal but it will work. The split washer will need to be large enough to cover the cable and the split should be on the cable to help it gain purchase.

Thanks all, especially for the terminology, they found some sitting in the bottom of a drawer at the third place I tried!
