    I decided to bring my Maserati Khamsin up to Dave Burnham, outside of Albany, New York to get my hydraulics checked out. The brakes, clutch, steering, headlights and seat controls all rely on this usually reliable system. Dave, who is one of the 4 recognized Citroen gurus East of the Mississippi, inspected the lines and said they looked fine. He removed the three green accumulators which are safety controls if one loses pressure in the system and checked them with a nifty device. One Brake accumulator was blown and the other one only read 150 psi instead of >1000 psi. He opened them up and rebuilt them with new rubber diaphrams, green hydraulic fluid (LHM) and Nitrogen gas. There's nothing like imminent brake failure, so it was a day well spent (at a very reasonable price). Citroen who owned Maserati in the late 60's and early 70's also utilized this system in the Bora and Merak.

    Dave keeps a bunch of Maserati engined cars around. He races the yellow open V-6 Maserati car on ice. It utilizes a wing to help with turns at up to 120 mph on the course. Off season he races a BiTurbo. Also pictured are some Maser engined Citroen SMs. A once in a lifetime driving experience ( a great highway cruiser, but the engine requires oil changes every 2000 miles and chain tensioning every six). It has sleek angular styling with a brooding, almost sinister appearance.

    Here's his other Citroen ice racer. Dave dominated the East U.S. for 14 straight years.

    I can only wonder how many Khamsins, Boras and Meraks are driving around with failing accumulators

    Here's a pic of my Khamsin and its 4.9L engine. You can see the accumulators mounted in the top right of the pic.

    It would be factual to state that these components are not individual points of catastrophic failure but there is redundancy amongst them. On my Bora, the 2 brake accumulators are separated from the 3rd accumulator which services the ancilliary, noncritical functions (seat pedal sled, seat movement and headlight buckets). The 2 brake accumulators are isolated diagonally across where one accumualtor services pressure to the Front Right and Rear Left, while the other services th FL and RR braking circuits.


    Failed accumulators do not always lead to catastrophic failure - the pump can supply the needed pressure for the braking circuit.

    The biggest problem with this system is that unknowledgable sellers (aka dealers) typically "top off" the braking system with DOT 3/4 brake fluid when the system needs a mineral oil based LHM fluid. DOT 3/4 harms seals requiring servicing.
