Navara brakes

[Struth]

I am getting a loan of a navara, an old one prior to the D22. I think it's an 89 model.

It has a 2.4/2.2 diesal and apparently there is a pump of some kind attached to the alternator that works with the brakes.

This pump is stuffed.

Can anyone tell me how hard this is to fix, I need to pay rego on the Navara before I can borrow it.

Cheers

It's a vacuum pump, no vacuum in the manifold of a diesel as there is no butterfly.

Just push the brake pedal harder

Yep we figured that already , are they hard/expensive to come by or are they cheap enough?

They usually come with the alternator as a job lot.

I think if you wanted one then genuine would be the only way, or second hand.

Struth, these things rearely fail. Are you sure it doesnt have a leaky hose?

They also have a check valve in the system to hold vacuum in the booster overnight, it might be blocked.

Run it with the hose off & if it sucks on your finger tim then it will be ok.

May also be a diaphragm in the booster shot.

Cheers mate, the guy who is lending me the car already has the alternator and pump apart after he was quoted $700 to repair it.
