Engine/Transmission (1994 - 1998) Exhaust brake sticks on

[SAndreasen]

My exhaust banks brake won't come on when it's cold and then if it does it sticks on I tore the black switch that the wires and hoses go to apart and cleaned and lubed it up doesn't seem to be sticking

Vacuum leak?

I van see a vacuum leak causing it not to come on but wonder why it sticks on that switch must be bad I guess

I think it takes vacuum both ways, on and off.

Ok thanks I'm sure I've gotten a vacuum leak some place because sometimes the air won't come out of the dash vests or defrost

With the PACBRAKE they have a special lube that you can buy for the cylinder, don't know what banks has. Good idea to check the vac lines first.

I had no power brakes for just a couple seconds today after stopping at the store guess I better start looking for leaks
