I've almost always been pleased with the stoption provided by Weinmann's centerpulls. I raced a 700c-wheeled mountainbike for 3 years using these, and only added a booster plate when steep descents on a wet course presented itself. I've since put another 7 seasons of 'cross on them. I've not had a problem keeping them centered, and this includes at least a half-dozen bikes over the years. I've always been amazed how any caliper with plastic bushings held up for a reasonable time, yet they do.

If I can find one real fault it's that the post's can become effectively shorter if the pivot bolts are heavily tightened, and this can cause binding just as it often does with cantilever brakes (tho a different "failure" mechanism is involved). This could be a cause of lack of proper centering but is fixable by sanding the bushing's flanges (or the arm's mating surfaces) down a bit, but not so much fun putting them back together as I recall!

I suppose the plastic-capped slider pin that attempts to synchronize the two arms of the Weinmann caliper can also induce friction if the brake is not set up straight, but it can also compensate for the cable carrier getting pushed to one side as often happens on a commuter bike.

Now Mafacs, these often squeel badly but do also deliver good braking power, and you've almost gotta love the look of those things.

>I agree with all of this. I'll also add that the Weinmann 999 centerpulls

\r?\n>rear was a bit difficult. The Universal centerpulls of the same era were

\r?\n>much better. The Mavic Racers were better still. The only worse brakes than

\r?\n>the 999's, IMHO, were the Weinmann sidepulls found on the Competition GS.

\r?\n>And don't even get me started on the old Universal sidepulls although they

\r?\n>to me. I didn't think brakes could work that well.
