Porterfield RS-4 brake pad problem

I am having a problem with the brake pad sensor breaking when put into Porterfield RS-4 pad. I have never had this issue with any other pad. I am thinking maybe the coating is to thick or maybe it's made wrong? I have broken 2 sensors and not wanting to make it 3 lol!

Just run with out them. You can just cut off the broken sensor and short the wires together to complete the circuit. That way it won't trip the service clock anymore.

never thought of that, so cut end off and connect the wires all together?

i did this too...eventually you get a hidden fault code from the system indicating your remaining fictitious pad life doesn't make sense relative to miles traveled. Discovered it recently, no big deal ....maybe something to check and clear before selling car.

I have these same pads and that's exactly what I did. Cut off the sensor strip the wires down connect them. Been fine for over a year. Also more convent if your constantly changing out different pads for the track. Although the reason I bought these pads was for not doing that. Closest I could find for street / occasional track pads. I had them on for NHMS HPDE and performed awesome.

Were you having this issue in the front, rear, or both? I am running R4S in the rear (Ferodo 2500DS in front) and had no issue putting in the sensor clip.

On another note, I am chewing through the rear pads in a hurrry (with track use), and huge amounts of brake dust compared to the Ferodos...going to try something else next time around.

just the rear, it's like the sides have to much material where sensor goes in. I am clipping end off and connecting wires together and forgetting dumb ass sensor.

I am getting less dust than my stoptech, but again your using yours on track.

Strange, maybe they changed the design and no longer fit for some reason.

Yeah, they are great for the street, overall good bite and brake feel, but they couldn't keep up at the track. From the reviews I thought they might hold up better for the track. They would be fine for some light track duty but if you start hammering on them they start to show their weaknesses. My front's held up terrific though.

I agree on them over the Stoptechs, that is what my PF pads replaced and they are definitely better and worth the slight increase in price IMO.
