Self-adjusting levers: New for '73, but some '72s got 'em, such as this one.

They are absolutely horrendous. The basic concept is about the same as the self-adjusting hardware on an automobile's drum brake. No matter what some may say about the design on the motor vehicle, Raleigh's contraption is worse.

Personally, for the "original" look on a '73-76 Sports, I'd open them up, glue the adjusters closed, then add barrel adjusters from an earlier Raleigh brakeset to the calipers. Simple as that, and the only thing out of the ordinary are the new barrel adjusters.

Granted, this is why I got rid of most of my 1970's-era Sports - sloppy workmanship, sloppier engineering. '64 and earlier were the Sports' prime; personally, I like the machines from the mid-1950's and prior; the plain Hayden lugs look good on them.
