I asked how to diagnose a problem....what are signs of caliper probs...

Here is decription of what I see.

less than 1 year on new set of pads & rotors, low KM's like about 15000KM, family car with kiddies so no crazy performance type braking. Rotors have not worn smoothly but have many grooves. LOT of material worn off rotor in this time...like maybe 1.5mm per side (3mm total each rotor). Haven't had the pads off to check for even wear, though.

Waddya think?
