Help brake switch vacuum pull to much

[Terry Sayther]

I would take the switch back out and see if the problem disappear---I think it will. Then I would get another nut so that the switch could be adjusted properly [as Henning suggests]. I have seen this symptom if the actuating rod is too long, and the switch adjustment too deep might be a similar cause.
