    Campy Veloce caliper re-assembly help

    Help! I took my 1999 dual pivot calipers apart for cleaning, the rear went together fine but the front is either too tight or too loose-no in between. Is there an exploded view of these calipers available? Is there a trick to putting them together?
    Thanks.

    Yes. Campagnolo has spare parts catalogs on-line dating back to 1994

    You need to hold the hex key in the bolt and pivot block it threads into steady when you tighten down the lock nut.

    +1 Shimano dual pivot brakes adjust the same way. The difference between too tight and binding and too loose with play is a VERY small turn of the adjusting bolt.

    IME the Campy brakes can be a fair bit tougher to get the damn spring in. It can be a right mission with a dual-pivot!

    Aside from the variation in the amount of hassle on that score, other variables include blind bolts that may lack a locknut and just use Loctite and a grub screw, or whether grub screws are present on both pivots or just the middle one.

    The last time I put one together I tried putting the outside spring leg in its little plastic bushing before installing the offset arm/cam/pivot bolt/etc. With the offset arm and cam against each other a small wiggle popped the cam over the steel ball in the centered arm and let me finish putting it together.

    It was a little different adjusting pre-load with spring tension but seemed to work great and was much easier than fighting the spring after the brake was otherwise back together.

    As a foot note those springs eventually fail due to fatigue so having spares on hand is a fine idea.

    I came across a pair of busted Campy springs on a bike once; had to kludge springs out of spokes. They were a lot softer being only 2mm (IIRC the springs are more like 3mm), but they did the job.

    I've never come across fatigued Shimano springs, and I've seen a hell of a lot more of em.
