Folks, about every other month, for a few days at a time, I will lose most of my vacuum, causing the brakes to be very hard, and causing me to sometimes have to open the hood to turn off the engine. I have sealed off the driver's compartment from the vacuum system, so it is not a leak in the doors. I have been told that there are some valves in the vacuum pump that are not working correctly, and that is causing the problem. My question is this:
How much of a hassle is it to rebuild or replace the vacuum pump? It is my understanding that I will need to remove the radiator, and that perhaps a kit exists that would allow me to rebuild the vacuum pump. Does anyone else have any experience with this, and is it a relatively easy and straightforward task? Thanks so much in advance!
