The “brake pad wear” indicator light came on today. It would seem my ’91 C4 needs a brake job.

My plan is to get the rotors off and resurfaced, install new pads, then take it to a shop (that has a Bosch Hammer) and get the entire hydraulic system flushed, filled and bled.

Before I begin, questions for the group:

(1) Curious, but how does this indicator/sensor work? How does it “know” the pads are worn?

(2) I’ve done dozens of brake jobs on other cars, but is there anything out of the ordinary about the 964 (C4)? Specifically:

(a) Can I get the calipers off the rotors and the rotors off the car without disconnecting any brake lines?

(b) Are the wheel bearings sealed or open (and require repacking with grease)?

(c) What else should I look for while doing this job?

(3) Any other hints or suggestions when doing a brake job on a C4?

(4) Finally, what brake pads do you like for normal street driving? OEM or is there a better answer aftermarket?
