Power Boost (Brakes)

[Marauder]

I have a Bog standard 2008 2.2 FWD SWB. I have Just received new REAR Brake Discs and pads to fit to my Transit. The replacement Discs and Pads came with 2 black leads about a foot long.I thought that these leads would be for the brake wear indicators. But on the Box that the new Pads.Discs,Leads came in it said with Brake Boost !! How can 2 leads boost your brakes ??? Can some one explain to me Exactly what these 2 leads are for PLEASE as I plan on replacing the Discs on Monday.

Got a picture of them?
Maybe foreign name, in Australia they call the disks rotors, yeah like my helicopter
I've heard mention that the transit has tandem brake boost system but never seen anything other than standard setup with wear indicator wires.

Probably fancy talk

Sorry not possible to get a pic on here at moment problem with the cam on phone. But the Discs/Rotors look just like any other Discs/Rotors.Im now assuming that the pair of cables about a foot long must be for the Pad wear indicators light on the Dash. However I have not heard of this Brake Boost thing.. I will make a start on changing the Discs on Wed as I'm just waiting for my small bottle of Loctite to arrive as I'm planning on using the big centre Hub nuts again instead of buying new ones.

ETIS build data for my 2006 and 2007 vans states they have "Power 4-Wheel Disc Vacuum Boost", but my 2011 van has no mention of it.

Obviously they all have a brake servo, which is the only thing I can imagine it means, but that wouldn't involve any wiring.

You're overthinking things....just replace the disks, pads and reconnect the pad wear looms and be done with it.

Ok Guys today I started to remove old Disc and pads also have managed to get that big Nut undone (What a Game) So wheel off, Torx bolts removed, Big hub Nut now off,, Any ideas HOW to get the assembly off I thought that the hub/and Disc/Rotor would just pull off so I could then set about getting the old Disc off (using the wheel and bolt method ) I started to undo the 4 bolts on the rear but stopped and thought IS it Necessary to undo the 4 bolts on the rear to remove the hub ????

You may need a new bearing and a stub if you are unlucky

Ok Guys, The Latest. I now have the Hub off,I checked and re-checked I had removed anything Holding the Hub. I put my thinking cap on and got my old trusty Hub Puller I had laying under my Bench. Fitted it to the Hub and after a few Tons of pressure the Hub started to move,It fort me all the way until the Hub came off, The reason I think who ever changed the last set of Discs and Pads never put any type of grease on the stub axle as when I removed the Hub from the Stub Axle everything was rusty and dry not allowing any movement. So there you have it,now I have to go all over it again on the offside next.... I have cleaned up the Stub Axle and ordered a new Hub with Bearings,,( Things like this only happen to me lol)

I didn't even bother with trying to pull the hub out of the bearings, just replaced the lot when I had a bearing die....bought two lots, pressed them together and now have a spare assy in my shed ready to go when the other bearing finally dies.
