Abstract

Improvements in drum brakes with internal shoes, characterized in that an automatic regulator is incorporated into each brake for one shoe or each shoe, equipped with first and second relatively mobile parts to vary the effective length of the regulator, associating the first part with a shoe and the second part with a brake actuation device, and a recovery spring that connects between the other shoe and the second regulator part, whereby the spring moves back the second shoe and the brake actuation device that it acts on the first shoe, but the load on the spring does not increase when the length of the regulator increases.
