brake trouble

I take a shot at this and suggest the inner lining of the brake line has collapsed on the side with little wear.

You got it backwards my friend. Collapsed inner lining on flex hose causes brakes to bind after application, causing more wear as the piston won't release or release very slowly, which causes the pads to drag and wear more quickly. So, if that is the issue, the side with more wear would be the side that has the bad flex hose.

Sounds like he has a sticky caliper on the less worn side. Could be the caliper pinds need greased or the caliper just needs to be replaced.

Check both front wheel spindles for a dirty or faulty ABS speed sensor.

Have dealer Read the voltages of each front speed sensor as each front wheel is turned....

A sensor cleaning or replacement might be in order......

GM speed sensor Part number is 15112379 at $62 ea or $110 ea.

I'm dying to know how a faulty ABS speed sensor could:

a) Cause the issue he is describing b) Cause the issue he is describing without announcing itself with the telltale ABS "whirr" and pedal pulsing c) Cause the issue he is describing without illuminating the ABS light and setting a DTC

You get my point.
