Brake booster Volvo Amazon (B20 2-circuit)

A spongy or low-sinking brake pedal, or a servo that hisses under braking, are common checkpoints on late 122 cars with B20 and a dual-circuit system. On these model years the servo was paired with the twin brake system, so the correct version is determined by engine and circuit setup – something to confirm before choosing parts.

This group includes complete brake servos, non-return valves and repair kits with O-rings for a leaking or sticky unit, plus filters, nipple as well as grease and plastilube for installation. When rebuilding, the diaphragm, non-return valve and vacuum connection are typical wear points to check. The selection gathers parts that fit the 122 with B20 engine and dual-circuit brakes, so that pedal feel and braking action are restored.
