Brains Trust Help - Vacuum Wipers

[Phil Waterman]

Hi Scott

Vacuum wipers when they are brand new and well lubricated etc are faster. But any kind of vacuum leak particularly in the tube going to the wiper or at wiper motors really slow them down.

Connect a vacuum gauge to wiper line if running down the road and you have 7-10 inches of vacuum then the wiper should work OK. My C60S Beauty has good new vacuum motors and with the new 261 engine that doesn't need to be run hard it pulls 10-15 inches at road speed an 25 inches when you lift your foot the wiper motors really do work well.

But what you see on BEAST is my typical experience with wiper motors. They are good enough to pass safety inspection but I really rely on the Rainx for keeping visibility.

Cheers
