Sensor on front brake pad

I checked my front brake on my 2000 tdi Jetta . I notice that the inner left pad was getting down so I removed the caliper . The sensor that works the worn pad is connected on this pad . How do I disconnect the wire from the connector ? I tried to pull it apart at the joint but it seems connected inside . any suggestions ???

I just changed out my front pads on my '00 Golf at 60KM. I had uneven wear on the driver's side front. When I went to replace the pads with OEM, VW wanted $209.00. I said forget it and just cut the sensor off short enough to go in the boot and spliced it with a butt connector.

Put on some great pads from Performance Improvements and I've been happy ever since. Nice quality low dust.

are those the Mintex? How much does www.performanceimprovements.com want for them?
