Found and removed a brake vacuum pump form a volvox at a scrap yard today. 

 

I was able to salvage the full system, (switch, connectors, vacuum hose, one way valve, loom mounting brakes, and a extra hose from another car) for the grand price of 11 pounds.  I originally had an Audi system, the Volvo pump seems to mount easier. 

 

It seems the Volvo pump is used to assist/top up the engine vacuum. It doesn't come with a  reservoir.  Northernpower has a great write up with an audi pump and uses a reservoir. He (as I understand) uses the pump to as a stand alone pump, I.E not engine vacuum. 

 

I currently do run 4 vacuum hoses from my 4 ITBs, It works, but the level of vacuum is a bit sporadic. I think I can just connect this Volvo system up as it is, keeping my engine vacuum lines also 

 

 

Wiring wise, its seems it is only a 12V ignition feed and an earth. 

 

Pictures coming soon.

Pump tested and working, I little but noise than i thought.

Polished and painted, not perfect, but not bad for a part from a 10 -15 year old Volvo

I decided the easiest way to mount it would be using the original bracket.

After some modification

Bracket and pump mounted.

Just needs plumbing in and wiring.

Hopefully  it feels like it is meant to be there also.

Vacuum pump all plumbed in and wired. Tried to keep it as neat as possible but there are quite a few hoses and wires, switches, connectors etc.

The brakes perform really nicely now. I now know that I will receive the same assistance from the servo every time.

 

The pump is a bit noisy, and turns on for a split second when the brakes are applied under normal driving conditions. I feel it will get annoying. 

 

I will look for a reservoir.

I've got an electronic vacuum on my 7 porter running from an ignition live.  However, I'm told that they draw around 15 amps when operating, and I feel that its pulling too much juice/current from the coil pack and ignition. 

 

Occasionally I get an unexpected  blip/drop on the tachometer and it  can cause the car to stall when under low load.  As a result I am thinking of running a fused constant live through via switch and hence taking it off the ignition live.

 

I'd be interested to know how you get on with your setup?

I keep you updated. 

 

I have wired more in via relay triggered by ign and with a fused live

Little update: 

 

The pump seemed to work fine. But then on one trip it ran constantly, so I had to disconnected it. 

 

In other news - I am a bit sheepish to write this - but I lost it on a corner and planted it down a ditch and into a field. Good fortune means that there is not a scratch nor any damage on the car. phew. Only thing hurt is my pride. Lesson most decently learned  :shy:  :shy:  :shy:  :shy:  :shy:  :shy:  :shy:  :shy:  :shy:  :shy:  :shy:  :shy:  :shy:  :shy:  :shy:

 

you can see where i went of (skid marks)

And where I ended up - Inches form the fence

On a positive was caught on camera again.
