Default Inserting pad wear sensors

I thought I would have my car back on road today, but the new pad sensors all round were difficult to locate in the new Pagid pads. On a couple of corners I could tap them in with wide screwdriver blade till they seated, but I managed to break the plastic on the other two corners (the "tongue" of plastic that slides into channel on side of pad away from rotor) so they no longer sit in the pad!

I know I can just tie them out the way till I replace them, but are there any tips for inserting them without snapping them? I was surprised that they needed more than finger force to push on, as on my previous 928 I was definitely able to push them in with no problem. The ones I broke were aftermarket items - maybe they just don't fit as well or have as good a metal spring clip as the Porsche items?

Probably the aperture in the pad- had a similar problem many years ago- just abandoned the sensors given they are there to warn Dentist's wives!

To make them fit you ill probably have to get nifty with some small files.

I think if you do that you will have a continuous warning light. But then, what do I know!

I just had the same issue, the plastic on the new sensors seemed very brittle.

I have another set now but will look at the pads and grind down material to make sure the sensors go on easily.

Not only me then - I was kicking myself for not managing something so apparentlyy simple!

I'll have a look at filing the slot a little.

Thanks all

Jerry so long as the wire loop through sensors not broken you don't get a warning.

But you would have warning if you left sensor out altogether, and had nothing plugged into the connector barrel behind the hub.

That's funny. I had never made a mistake before. I thought I had once, but I then was wrong.

^^^^ This ^^^^

The pad backing is a nice steel stamping, and I'm sure the little cut-out for the sensors was perfect on the drawing and may be similarly perfect when the metal is initially cut. During manufacturing, the pad material is cast/formed/sintered/whatever on the metal backing, and some undoubtedly hides in the sensor cut-out. The backing is then painted to make sure there's something in the cut-out when you receive the pads.

After several clinic sessions as well as a couple pad changes on my own car, I'm convinced that a few minutes with a set of cheap jewelers' files is the key to getting the sensors to go in correctly. It's even more critical if you plan to remove the sensors sometime in the future; you'll need room to squeeze the little locking clips, none available if there's paint clogging the opening.

Just drill a hole for the sensors - it's not rocket surgery.

I ditched mine five years ago, never looked back.
You will likely be working on your car frequently enough, you can manually check your pads for wear.

You can by pass the sensors in the fuse box and the light won't go on?

So there may be a better way, but, what I did was pull the sensors, then jump the wires to each other, then plug sensors back in...no warnings that way on the 86

My double-top-secret method for keeping the warning lights off is.... Don't tell anybody! ....




















Replace the pads before the wear sensors get used up.

A little work with a toothbrush gets the crud out from around the sensors, and they come out of the old pads easily. Dress the holes in the new pads to remove the paint, pad material and other crud, and the old sensors fit perfectly into the new pads.

Voila! Problem solved, plus you get to keep the sensor function.


HTH!
