ABSTRACT:
A side-pull caliper brake device comprising an arch support pivot, a first arch and a second arch rotatably supported by the pivot, first and second return springs each in the form of a coil and fitted around the pivot for biasing the first and second arches away from each other, and a Bowden cable for moving the arches toward or away from each other. The first spring has one end engaged with the pivot and the other end engaged with the first arch. The second spring has one end engaged with the second arch and the other end engaged with an adjusting ring rotatably mounted on the pivot. The adjusting ring is prevented from rotating relative to the pivot by a fastening nut. The force of the return springs is adjustable by rotating the adjusting ring. The springs are engaged in place without sliding and therefore smoothly bias the first and second arches. The springs, which are provided around the pivot and enclosed in the cavities, are free of deposition of mud or the like and protected from corrosion.
