Hello All,

Driving home the other day started to notice a strange mechanical hum in the cabin. As best I can tell it is coming from the thing highlighted in the pic below. Im pretty familiar with these cars, but I'm not sure what this is. Appears to be some kind of pump, and mine sounds like its on its way out. Any help is appreciated!

The vac switch under that black filler panel behind LF headlamp in engine bay is what turns it on when vacuum is low. THe switch often breaks and the pumps runs constantly.

So I replaced the pump and the switch this weekend, and now the break pedal is HARD. Is there a process that I am unaware of when replacing these? I've double checked all of my connections and both are working, however it takes a lot of work to get the car to stop.

Thanks!
