My brake vacum pump has shat it's self. It was like trying to stop using only my feet!!!
Can you have this fixed?? I can buy it new from nissan for $640.00. or get a changeover alternator from the wreckers $400.00. Its more money then i've got. If anyone has any sugestions???
Thanks

It' a pain, but you would be better buying a new one or get yours overhauled. It cost me around $600 to rebuild mine.

The problem is the shaft that drive the Vac pump is sealed with an O ring which wears the shaft if your lucky you can rebuild the pump relace the O ring and it will work, but if the pumps done a fair bit of work, you could find it will leak oil.

I wish People would put there location in the posts!!

Where are you?

Mine did the same thing. There are splines on the end of the alternator shaft which engage with the rotor on the vacuum pump. In my case, the splines stripped, meaning there was no drive to the pump. I think in most cases this is what happens as there is not much else to go wrong with these pumps.

I found an auto electrician (the first one I tried) who was able to rebuild the alternator using an aftermarket alternator shaft and vacuum rotor. It cost me about $280. This included a new diode pack as I had wrecked mine by welding on the vehicle without disconnect the battery and the alternator.

Try contacting an auto elec and asking for a non genuine alternator it should cost about $380 for a new alternator and vacuum pump all in one unit. These are generic alternators that are made to suite navara patrol or urvan, some minor alterations may be needed to vacuum tubes that come into the pump itself. this is a much cheaper alternative for a new set up.

Also I did not know that your location made a difference when you were asking for advice. Good luck

Good advice there.

Location can help if a poster was going to recommend a trusted service provider (auto sparky in this case) in the area close to the person asking the question.
