I changed my 1985 300TD's front brake pads several weeks ago and have been driving the car with no problem. However I noticed the front right outboard pad was worn more than the others. Now yesterday after driving , I was going to wash the car and was spraying water on the wheels. Nothing on three of the wheels but the right front disk was hot enough to sizzle when the water hit it ! Is there anything I can do short of taking it to a garage to rebuild that caliper?

More than likely a caliper job, but don't
overlook the common possibility of a restricted rubber flex hose. As they age ,they will allow the brakes to work under the pressure of the pedal, but not let the fluid release back to the Master cyl. because there is not enough pressure in that direction. That makes the pad hang up on the rotor.
A quick test for this is to spin that wheel
after someone pumps the brake. If it is hard to turn after letting up on the pedal, open the bleeder. If it immediately frees, it will
indicate a bad hose.

Also, I think this is a single piston caliper, and the caliper has to float to compensate for brake pad where. If this is gummed up or rusted, it will tend to cause the brake to drag and wear unevenly.

I know you put new pads in recently, the first two causes mentioned will cause even brake pad wear, and my comment, causes uneven wear. Do you remember what they looked like? Call me at home before 6 pm if you want to discuss! I'll be away until Tuesday after that.

Well now what ? I checked the pads and they seem to move freely . Also the brakes release when the pedal is released. I admit I did not repack the wheel bearings. Could they be heating up ?
