R32 Abs And Dead Brakes

[funkymonkey]

Hey guys, the footbrake on my R32 doesn't work unless you pump the brakes a few times. This is usually the indication that there's air in the system and it can be very easily fixed if I bleed the brake lines to get rid of the air.

However, my braking system has ABS as well, and I just noticed the other day that there was a little oil just underneath it on the turbo shroud and a little down the side of the unit, as if it had dripped out of the ABS unit.

Here's what I'd like to know from those in the know:

Is my ABS unit faulty, or is it a matter of me replacing some washers/connectors on the pipes.

Can this be the reason that my brakes are dead, as if oil can get out, air most probably can get into the system.

Is there any way to isolate the ABS unit out of the brake system to check if it is faulty (or even leaking for that matter). I have a switch which I can use to turn ABS on and off, if that helps.

I will add some pics tomorrow if it'll help. I do have a spare ABS unit on hand, but I'd prefer not to swap it in to find out it makes no difference, so I'd rather somehow isolate the existing ABS unit out of the braking system to check what is at fault.
