Default Brake pad warning light Continued Help!!!!

OK Thanks to all who gave me helpfull hints to check in my first post. At this point this is what i have done. Checked all four wheel sensors. All four check out. Thin tried jumping all four sensors at the same time to eliminate any possable bad connections by the wheels or sensors. I have followed the wire lums as far as i can to look for a broken or warn wire that may be grounding out with no such luck. This is really getting fusterating having light on in dash all the time and to have to cancel out the warning light every time i start the car!!!!!

If anyone has any further suggestions i would love to try them... I read in some other posts something about the brain possably malfunctioning??? Were is the brain for this particular sensor?

Did you get way up above the rear suspension where the loom comes out of the trunk/tire well? Mine were broken there and hard to see. I have heard of some who go behind dead pedal and loop the 19/20 brown wire together to complete the circuit there. This is not a fix just a short cut for now. Do not know about your year though.

Did you check the fluid level?

fluid level would not cause a pad light, it would cause a brake light. and i second the idea of checking in the battery well where the wires enter the cab. common spot for issues.

Check where the wires run near the exhaust on the right rear...

Randy - Daniel lives up the street from me. He is always leaving black streaks in front of my house. Someday we would like to get together in Cbad someday with the locals.

I have the same problem but I think my pad light is due to a broken wire on a brake sensor.

Thank you all for your replies. I will check the wire were it enters the cab. i will let you know what i find today as the rain comes makes a perfect excuse to work in the garage!!!

It is most fun to taunt Mark with black marks in the street in front of his house as for the past year if i remember correctly i kept getting texts that he was driving in the mountains as my car was fully disassembled in the garage!!!

This is what I did a couple of years back, I never needed a pad warning light as I inspect them regularly !

OUOTE(--
Well I have an update, and hopefully some help to others who are fed up with this stupid "Brake pad warning" light.
Today I removed the rear wheels, cut off the wiring into the pads, traced where the wiring went, up into the trunk, pulled the wiring from underneath into the trunk, and cut it to a tidy length, soldered the ends and clipped it to the wiring harness already in there.
Cut the front wires and joined them using solder and heat- shrinked them.., still the bloody dash light warning was on.

So I decided to locate the central warning box ( yellow plug and black plug), after reading on here I located pins 19 and 20, released these, and jumpered them.., still the warning light was on the dash, then took a look in my workshop manual and decided to remove pin No6 the one that illuminates the dreaded light.., RESULT !! Could,nt believe after all that, the warning light is off !

I replaced pins 19 and 20.., wish I,d just removed pin No6 in the first place, although I have never read of any mention of this pin ?

Hope this helps someone, before they resort to pills and whisky.
BTW.., the central warning box on an OB..,

UK model is located under dash extreme right hand side.., not under the footrest, or above the dead pedal.

( This of course wont apply to US LHD)

I have my pod out for recovering so decided to pull the brake pad bulb so I never have to worry about it.

You could also bridge the terminals at the central contol unit plug thats what I usually do just in cases there is a broken wire somewhere I can't find.

Update:

well traced the wires as far as i could with no luck of finding a broken or damaged wire. Is there a way i can test each wire loop from the control pannel to see if it has continuity??? maybe at leasst working backwards to help deturmin which wheel loom is giving issue? There has to be other ways to truble shoot this matter as i really dont want to just disconnect the bulb... And even if i disconnect bulb every time i start the car i will have to turn off the central warning light!!!
