Power Brakes

[BigEd]

After the truck sits anywhere from 3 hours to overnight, it seems to lose the power assist until I start the engine. Is it normal for the hydroboost to leak down? I have a 5 speed manual and park on a hill. I noticed I have no power brakes until the engine starts.



Many thanks!

I can try mine in the morning and see if I still have assist. I never tried it. I'll let you know.

My truck sat overnight and it had about 7 pumps before it started getting hard. Hope this helps Big Ed. There has to be an accumulater. (sp?) If it has a leak the reserve pressure will leak down and you will have no reserve.
