Vacuum lines on brake booster.
I replaced master cylinder and brake booster a year ago. Brakes work, but don't seem to have the power that they should.
Lately, noticed an axle seal leak into the rear drum. So in the process replacing the seal and cleaning up drum. I noticed in the Mustang Shop Manual that they show using both vacuum ports on the check valve for the brake booster with am automatic.
So are both lines supposed to be hooked up to the intake for vacuum? Never noticed this difference before.
