W124 1987 diesel
three wheels hot one wheel cold

My wife brought my W124 home with the brake pedal fading to the floor, still braking, but not very nice for the sane people!

Next morning I drove it, it was fine.
Then I drove it with the brakes on for a minute, stopped and felt the wheels. 3 were warm to hot as you would expect. Rear passenger wheel was only slightly warmer than the air temp. Tried it 3 or 4 times, not crazy, one wheel is definitely much cooler.

My mechanic (I have given him 2 dead W124's over the years) might let me steal a caliper. Should I?

mileage 446,000 Km

300E 1989
great car!
