Re: Vacuum line to brake booster?

Too true. Without the vacuum assist type the wipers may stop at a critical moment and reduce vacuum to brake booster. Drove for years with just manifold vacuum off the 235 with factory brakes, The "swish chunk" of the wipers was an old familiar sound as was being blinded by rain when I stepped on accelerator. The electric isn't that big and i hear there are smaller units now.

Yes reliable wipers are very essential here. Got caught in a gale coming back up 101. 45 MPH+ wind and inch a minute rain for a while. Reminded my of monsoon in SEA jungle so long ago. BTW ADs have all the aerodynamics of a
boxcar.
