Earlier......I was struggling to get the vacuum hose off the outlet of the aaz vacuum pump. While twisting and torquing on the hose to break it free, I noted that the outlet on the vacuum pump now spins, when it didn't before. I have I made a vacuum leak? If so, how to fix?
My brakes are not working well......brake booster may not be working.....will trouble shoot today.
Does anyone know what the vacuum, Hg, inches of mercury, should be for the aaz at idle? and more rpms?
Thanks.
