Please help. Newbie with a fluid leak on passenger side; Oil leak down passenger side

Hi, I have just purchased a 2001 Iveco Daily 2.8. I have had it at home for a few hours and gone out to it where I noticed what appears to be a fluid (oil) leak on the passenger side. It looked to be coming from above the fuel tank. At first I thought it was diesel but it feels more like brake fluid, and looks as though it was dripping onto the tank. I moved the van so I could try and have a look underneath as it was getting dark, then I popped in the house to get a torch, and when I came back it had got a lot worse and now looks like its coming from near the rear passenger wheel. I can see it dripping from around the chassis back and above the rear passenger wheel, but cannot seem to source where it is coming from.

I am a total novice with mechanics, all I can tell you is the fluid is almost clear in colour (slightly yellowish tint) and doesnt really smell of anything.

Anybody any ideas what is wrong?
Thanks.

Firstly as you dont know where leak is actually coming from from a safety point of view check your brake fluid level, obviously if its low you can go from there and source the leak.good luck . Paul

Thank you for the reply.
Its definitely brake fluid, I got in the van this morning and the brake pedal goes straight to the floor. It looks like the source of the leak is somewhere above the fuel tank, but I cannot see if it is a continuous piece of brake pipe from front to back, or if it has a join in it somewhere above the tank?
Looks like I got a busy weekend ahead learning about braking systems :)

Thanks.

Can't help with joints near the fuel tank, but check the load sensing valve that is directly above the rear diff. If its leaking the fluid could be running back along the brake pipes before dripping off.

Thanks Spooky.
You was in the right vicinity. It just had one corroded mild steel pipe at the rear, the rest had already been replaced with copper.
I managed to get a replacement made up today so going to get it fitted and bled asap.

Cheers.

What a nightmare. Couldn't get the pipes out of the box at the back, the bolts were seized in. I had to cut the pipes to get the box off to extract the awkward one, so now got 4 pipes to replace :( Not a big problem, but I cannot work out why 2 of them appear to be 11mm while the other 2 are 12mm. I would have thought they would all be the same?

Oh well, hopefully back on the road on Monday. Fingers crossed.

Cheers.

Removing old brake pipes never seems to go easy ! remember on the back axle if it is fitted with a load sensing valve this needs to be compressed as if van is loaded to bleed brakes,easiest way to do this is remove axle end of it and compress and tie it up in this position with a piece of rope or similar untill you have fully bled then re instate.
hope this helps .Paul

Thanks for the pointers Paul, greatly appreciated. I have got the van back on the road today, after replacing 4 pipes. Unfortunately the n/s front bleed nipple was rounded off but I am pretty sure we got all the air out from the other 3. The spring that holds the load balancer snapped when putting it back on, so I need to source one of them, if anybody has any idea where I could get one from?
I will also need to remove it all at some point as the pipes we got made-up were all too long making it look a little like spaghetti junction underneath :(
At least it is working again.
Thanks again.

Glad to help,regarding rounded of bleed nipple,buy replacement nipple from local iveco dealer,then get a small blow lamp..the nozzle needs to be no bigger than your finger!...heat the area surrounding the old nipple,take care but get it quite hot,hopefully that should enable you to get the old nipple out using mole grips or similar.
It may snap off which means you need a complete caliper unless you can get it out useing easyouts(ask at local motor factor) If you dont heat it up its way more likely to shear off.I have done several like this with complete success so far,the one I didnt heat snapped!
Obviously common sense tells you not to get it red hot or that hot that heat transferance damage internal seals. Paul.

Thanks Paul. I think now it is mobile again I am going to take it to a local garage I trust and get them to sort the bleed nipple and maybe shorten the pipes that are a bit too long. They can also check the load balancer for me and give it a clean bill of health.

Thank you again for all your help, it is greatly appreciated.
