Brake systems on Turbo Regals
86 Grand National Did all of them or any have powermaster brakes Hydroboost or vacuum and if so how can you tell what your car is supposed to have?

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. |

Sorry I know a broad question, but I still haven't seen EXACTLY what part it is that apparently fails a lot. thanks! |
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. |
