break pad warning light, broken wire rear axle

[mickvgma]

hi guys,
mk7 transit 85ps 280
I have no clue with electrics and wiring etc, I have a break wear warning light on the dash, been on constantly since ive owned the van,
after searching through the posts here I had a look under the van and have discovered an issue with the wiring that travels along the rear axle to the off side rear wheel.
can anybody advise me what I can do to sort this out if any?
ive attached a pic and hope its clear to see the problem.
there is a red and yellow wire coming along the axle which looks like its been cut, the confusing part is the connector a little further up has this read and yellow wire protruding out of it along also with a black wire? not sure where this black wire should go as I can only see the read and yellow cut wire.
hope all this makes enough sense ..
any advice will be thoroughly appreciated
cheers guys n galls

The brake pad wires are basically 1 wire from the speedo that loops to the 4 corners and gradually goes to earth, any of the pads wear out and they cut the wire which brakes the circuit, some have them going to the pads and some just have a loop short at the plug.
Your case seems that you have 1 wire visible so connect that to the same colour wire that is coming from the plug which is also visible then follow the wire back to the loom and you should find another wire that matches the other wire colour on the connector, join that to make the circuit and you should extinguish the warning lamp
It is possible that the wire wasn't very secure and has Bern bouncing up and down which caused it to snap you should cable tie the wires securely but give allowance for movement where necessary (corners/linkages/armatures etc)

You can just link that wire that you see straight to the other wire which you need to find at the loom, provided you have a pad wear sensor on the opposite brake pads, you only tend to get both sides from fords, you rarely get the sensors after market

ive had this on my front wheel van where the sensor was on the front nearside only. the cable had gone brittle and snapped so i just shorted it to the cable next to it running to the plug, as long as you check your brakes regularly it should be ok.

That system is a bloody nuisance!! 2 years ive been looking at the light on the dash

What was wrong with a spring in the pad that squealed when the pads went low

If you have a mk7 just unplug the speedo and bridge pins 15 and 18 then plug the speedo back in

hey thanks so much peeps,
had another look and the problem seems to be the wiring between the two rear wheels as mentioned above, somebody has been here before me as the wiring has been messed about with.
so as I stand now I have the connector from both sides now off the van, the confusing thing here is the connector for the right has gray/orange and red/yellow wires, the connector for the left has a white and brown wire.. I can only assume these four wires should be connected together? even if they are different colours?
I know the right hand side has defo got a new wire set as in the pic the sleeve is blue and looks a lot cleaner and newer than the left side so maybe the wires wont match in colour.. im feeling really stupid here but my common sense tells me to just use new wires and connect the two sides together, can it really be that simple???
im a little worried as obviously people before me have been here at the wiring and for what ever reason have altered it all which is why the light is on the dash,
so why would they alter it when it would appear to be a fairly simple fix?
please excuse my lack of knowledge,,
many thanks again

Rear brake sensor LH is blue/green And gray/orange.
Rear RH is gray/orange and brown/blue.

If you earth blue/green according to the diagram, you'll bypass all 4 sensors, I'd try and get them right tho imo but at least on the left front and rear and just short the right ones if you want as you will change a set of pads per axle anyway
Ps. Ignore the pad side wiring as it may well be different, you want the loom side, despite them being different colours, they are in fact 1 continuous wire to the speedo.

this pic is of the left connector and the right connector,
left connector has one brown and one white wire, the right connector has red/yellow and gray/orange wires.
confused and don't want to give up so any last comments for me id appreciate it

1 of those don't look right to me check the front connectors so you know what is what and if need be follow the loom from the axle to the chassis and open it up a bit to see the wires

the left one is wrong in the picture

im indebted to you kind sir

I thought I'd sorted this problem out on mine today (I traced a broken wire in the circuit & fixed it), but just went out earlier and the light's back on

I was going to bridge the pins as above, but the main connector on the back of the speedo (the one in the centre) only has 16 pins. There are also 2 other connectors, both of which are smaller (a right-angle connector on the left, a straight one on the right). Therefore none of them have a pin 18...

I've got the MOT booked for 1pm tomorrow, so need to get it sorted by then. Which pins are they? A picture would be a great help!


TIA,


Jonathan

Pin 15 needs grounding, pin 18 is ground.
If you have a mk7 transit it is the connector on the left back, i have only seen 1 connector on them so it will be that.

Hi loot can I ask what color pin 15 & 18 are?
Cheers

Pin 15 blue/green

Pin 18(ground) black/violet.

When you unclip the connector from the speedo you can withdraw the inner connector there's a tab that you lever out with your fingernail, you see the inner connector has numbers on it, 15/18 are on the same side.
