Why don't you try buying new shims and put anti-squeal in between Mine aren't squealing. I have the bottle of disk brake quiet and spread it on them like jam and they stopped squealing. Try that before you hack up the sensor wires.

 

I can't find Akebono shims anywhwere. Where do you find shims?

 

I'm going to Audi for mine. This link is for the rear shims I didn't see front try calling them. The shim basically protects the disk brake quiet rubber crap from being worn away. I spread it out on back of the pads put the shim on and leave them to dry then install them. Copy it to your bar.

Update:

I purchased Centric brake pads from thepartsbin.com. Their pictures and their customer service says that the pads do not come with the wear sensors but when mine arrived the did in fact HAVE BRAKE PAD WEAR SENSORS on the front pads.

I got front and back pads for $96.00 shipped!! And they come with shims so I no longer have any squeeling noises.
