Re: Brake systems on Turbo Regals
The 1984-85 cars had the Hydroboost system with the LM9 engine.
The 1986-87 cars had the PowerMaster (electric) system.

Re: Brake systems on Turbo Regals
The accumulator bulb is probably the #1 failure. It looses the high pressure nitrogen gas charge eventually. My 45K mile car has gone through at least 3 of them that I can remember.
The brake switch on the unit sometimes will develop a leak around the connector (and there was an early recall to replace the switch with a new design). Occaisonally the pump motor will die ... usually from running too much/too long due to leaking internal seals in the MC or a bad accumulator.
