Bleeding brakes

[Guinn]

Would someone please tell me the location of the Pressure Differential Actuator? Just got my new brake hoses from Tony and will install them probably Monday.

Is that the white plastic thing under the master cylinder?

I think you're talking about that funny shaped thing on the inner fender to which all your brake lines run (usually called the Pressure Failure Switch & Body Assembly)...When you're bleeding your brakes, you should disconnect the wiring to the pressure failure switch & then unscrew the switch out of the body about 3 turns so it doesn't make contact inside the actuator.

I think...

My pressure fail switch is screwed into the bottom/center of the master cylinder... White plastic with a metal plunger.

You have a boosted brake system - he doesn't.

Sorry, I thought he was asking about the same 78 B he mentioned in the other thread.

 

[tony barnhill]

Oh, well if he is - I'm dead wrong! & the actuator is up inside the master cylinder...but you still disconnect the wiring & back the switch off.

 

[Guinn]

Yep. Just one B and it is a 78 I should have said so in the first place. Thanks, all.
