Brakes

[SpoolinGN]

I have a moroso line locks on my 86 GN. and recently they can't hold the car back anymore. The brakes stop the car fine but can't hold it, it just pushes right through.

Just today, if i hit the brakes in a panic stop, the pedal won't move at all, and the light comes on until u let off and push them again.

Could this be the fuse to the motor. Because i just put it on brand new last year when the other one went out.

Thanks for the help

the power master system in our cars gets kinda expesive to repair/replace parts- its either your pressure switch, or accumulator ball-

you could convert the car over to VACUUM brakes:
purchase here

or if auto zone is still in business in your town, you can purchase a complete remanufactured power master system, with new switch and accumulator- call for price

Run, don't walk, to these links and learn everything you can about the powermaster brakes in your car so you fix the problem before it gets very $$$$$$$$.

Sounds like you need a new accumulator but follow the troubleshooting guide to be sure.

The whole system is brand new last year Poston's. Why would anything go out so fast like that.

anything is possible, just convert it over to vacuum brakes and then you wont have to bother with the powermaster systems ever again-
