Not uncommon on older bikes for the reach of the rear caliper to be greater than the front. Many sets of brake calipers were sold with that differential during the 1960s & 70s. - In fact...









... [Sorry Folks, these are not for sale] ...


And, Yes ... I did pay a fair bit more than the original $15 price which was still marked on this box.

Do note, the dried and very hard original pads on these really SHOULD be replaced for actual use. They would not be effective at all on any bike. - Fortunately, KoolStop "CR" (Campagnolo Replacement) rubber pads - in either red or black are still available. Here is a set from a Seller on eBay and they're available elsewhere too. They are a perfect fit for the original Universal holders and sell for only $20 or less. They're among the very best brake pads made, so a very good bargain!

SJX426 - pairs of the correct replacement hoods for the levers are also often available on eBay brand new and very supple, but you can expect to pay premium prices - around $40 to $50 per pair. But I think they're worth the price because they're becoming increasingly rare and they are very soft, thick and cushioned... and they should last for many more years of use.

Shown below, you can see that the bracket through which the handlebar clamp mounting bolt will pass is actually pressed against the bottom of the brake lever body. - An unfortunate design issue. Over-tightening the bolt would pull the bracket against the lower body until it could eventually fracture and finally crack right at the bottom. I've never had a lever fail, but knowing about this problem, I am always very careful not to tighten the clamps excessively. ... Always something to watch out for if looking for a used replacement lever - without actually seeing the piece up close.
