Default 3dr brake servo stopped working.

Started my 3dr up today and the servo pump isn't working any more, what would be the first things to check? Is there a fuse or relay any where?

Check the wiring to the pump at the bottom or the push on connector..
Had loads of issues with mine till I sorted the connector

I've had a good push on all 3 connectors with the ignition on, still not getting the pump going.
Put a multimeter on the pump wires and I'm getting 12v, so I thought it was the pump.
Found an old servo removed the pump and plugged it in but still nothing.

Will it be the pump it self with having power? And the spare pump knackered?

Never know of pump packing up, be very unlucky to have 2 dud ones..


Are you sure the plug is making a good connection to the pumps?


Only things I know are poor connection and the fuse/relays under the dash on the drivers side but if you have power then it can't be those

I'll have another look at it again and give the connectors a clean up and see what happens

Have you got both plugs on the cap plugged in as well? (obviously with enough fluid)

Yes mike got them plugged in, I'll double check the level but I'm sure the fluid level doesn't stop the pump from working.
I had it out 1 day then the next time I started it the brakes weren't working, no pump working.

Iv not looked and this is only a theory but if your gettig 12v to the pump is it possible that it is switched on an earth.

And the pump is not getting switched on

Like a say I don't know how these are wired up as iv never looked but dose seem a bit unlikely that 2 pumps are dead

Anyone know which is the fuse and relay for the abs?

Also what's the 3rd plug on the master cylinder for?
1 plug goes to the pump
1 must be the pressure sensor?
