ABSTRACT:
An automatic braking-gap adjuster system for hydraulic brakes having an adjusting nut and bolt combination wherein the nut engages threadedly the bolt, the combination being disposed in the hydraulic chamber defined by a piston slidably inserted through an associated cylinder and a portion of the cylinder facing the piston, and the adjusting bolt abutting at its clutch section against a clutch face of the portion of the cylinder. A spring retainer having its legs fixed to the piston so as to be engageable with the adjusting nut such that the nut is restrained from turning, and a spring arranged in a contracted state between a spring seat of the spring retainer and the adjusting nut for biasing the adjusting nut toward the piston are provided. The spring retainer is mounted in place by inserting its legs through notches formed in the adjusting nut and holding them in openings formed in the piston. Alternatively, the spring retainer is mounted in place by holding its legs in openings formed in a collar adapted to define a cup chamber of the piston, the opening being in communication with the hydraulic chamber. Thus, it is unnecessary to provide any separate holder on the piston, which would otherwise render the production of hydraulic brakes more difficult. The adjusting nut is engaged with the end of the spring serving to bias the adjusting nut toward the piston, whereby it is kept from turning.
