I just ordered a new set of brake pad wear sensors from pelican for my '87 951 (with the standard 4 piston calipers) and received the part pictured below. The ones that are on there now contain two sensors per caliper (one for each pad, wired serially to the plug), vs. this part (951-612-212-00-M163), which contains one sensor per caliper. Is this what porsche now specs for our cars, or did these guys send me the wrong thing??

 

I can't help you. I've got to the point where I never hook them up anyway and find them to be a nuisance and hard to transfer between pads with breaking them. I have my wheels off so often I just do a visual inspection and pull the pads in under 60 seconds to really see whats going one. I never knew that the 87 had two sensors per caliper...and I thought just one was useless

 

What Steve said. I will never use them again.

 

When eliminating, do you just short out the leads to keep the idiot light from coming on?

 

I just slide the sensor out of the pad, loop it, and Ty-Rap it to the brake line. If you unplug them at the connector you need to short the pins I think to keep the light from coming on but why do that if you just pull the sensor? It's a no brainer.

 

KLR....sorry for hi-jacking your thread!

KuHL 951......I just replaced my torque tube. While the
rear suspension was down I eliminated all that wiring
for the wear sensors and shorted out the wires way up
by the fuel tank. Makes for a much cleaner sensor delete.
Why would you want to delete the sensors and leave
those connectors and all that wiring in place?
More over, how cheesy is it to zip tie the sensor itself to the brake line??
Sure seems like a no brainer to me. To each his own.

 

I guess if I been at the point where I had yanked the torque tube I might have done the same. I'll let the next owner decide if he wants sensors or not...I wasn't at a point where disemboweling the brake wiring was my primary goal. hey what's wrong with cheese? You got some kind of bovine hate thing going?

 

OK -- I'm getting the picture that most people are shorting this circuit. Anyone know whether the part pictured above is usable for an '87 951 if one wanted to keep the sensor functioning?

 

KLR....those look like the ones I just removed from my '88.

 

KLR I had both kinds on my '89 when I bought it, and it worked just fine. I think I read somewhere that the one pictured above is the older style. Both kinds work, but the older style just monitors wear on one pad, and the newer style checks both pads, which is good if your pads are wearing unevenly. Like the others, I don't use them any more.

 

Yes that part is totally usable on your car.

Thanks guys
