Master cylinder Brake Volvo Amazon 2-Circuit (B20)

A sinking pedal, leaking sleeves or a spongy feel after a longer period standing still are classic signs of a worn master brake cylinder. This category gathers parts for the 122 with the B20 motor, which arrived in August 1968 and ran the last two model years – exactly the period when the dual-circuit system became standard. The dual-circuit solution splits the front and rear brake into separate circuits, so a leak no longer empties the entire system at once.
