I removed one brake wear sensor from each of the front and wheel wheels when I tore down the brake calipers to be rebuilt. In pictures from diagrams, it looks like each caliper might have two sensors, one per brake pad. Is this the case? or is just one wear indicator required for each wheel caliper?

Depends on what you mean by sensor. No experience with cars 86 and older but on 86.5+ there is one cable with two wear sensors per wheel, one sensor for each pad.
Kevin, I must respectfully disagree on a point. My 1986.5 only has one sensor per caliper.
Seth, thanks for correction! I understood that the 86.5 got the S4 brakes so made a bad assumption that it would have gotten the same sensors. Exactly why I stay with 87+ cars!
The dual sensor is a logical upgrade for pre-87 cars, as it looks at wear on either pad in the caliper. Meanwhile... users post regularly about how to bypass the system.
The pre-S4 calipers tend to wear the pads on the piston side faster than the outer pad, so it's east to justify one sensor on the single piston brakes.

How many brake wear sensors per wheel?
