Default Good day wrenching on the Cayman, 2 questions

Son Coop and I had a good day doing our first routine maintenance on Pepper 2.0. Oil change, replace air and cabin filters, and replace the brake pads.

Removed the front pad brake sensors and the replacement stock pads did not have the hole to replace wear sensors. Considering that I check them often enough, I don't need no freakin brake pad sensors so I just folded them up and tie wrapped them to the plug. Would prefer to just cut the wires and be done with it but not sure if I need to wire nut the 2 wires together or separate so I don't get the warning, which is it?

Also, After reinstalling the retaining pin that holds in the pads on one of the rear brakes I lost the small retaining 'cotter' pin while trying to install it. How important is that little pin, as hard as it was to get the pad retaining pin out, can't imagine it is that important?

The brake sensor circuit needs to be complete to avoid triggering the warning. When the pads wear down the sensor is eroded and the circuit is broken. I just wrap the sensor end in tape and zip tie out of the way.

I'd sure want the retaining clip in place. The concern would be vibration causing the spring retaining pin to work it's way out of the caliper body. It would only have to move a sort distance for one pad to not be fully secured by the spring. I usually replace the whole set -spring, pin and clip on every other set of pads which is also when I replace rotors and caliper bolts (for track duty). I wonder if auto parts store would have the little clips.

Thanks, that what I figured about the retaining clip, will check at NAPA and/or order a bunch from Suncoast.

Yeah, I't replace the cotter pin. It probably fell down into the hub or caliper area.

NAPA or Lowes did not have right retaining pin so I shade tree'd a temporary pin and will order the replacement brake pad retainer clips from Suncoast. Taped up the brake pad wear sensors and installed the GT3 Brake Ducts. Great weekend with the boy!
