Just thought I would ask for some opinions. When I press my brake pedal, I get a small momentary increase in rpm, and then it drops back down to normal. Would you say my brake booster diaphram is leaking? Thanks! John.
when your brake booster leaks vacume enough to change engine rpm you should be able to hear the leak.i had the same prob and when i pressed nice and hard on the pedal the leak would go away and rpm would drop slightly to normal. and yes it was a bad booster
