Subject: Front disc rotors - something funny going on?
   Date: (none)


Was out rotating the tires this weekend on my '91 Miata (15,000 miles.)
While I had the wheels off I though I should check to see that things
were doing OK in there.  Rear brake pads and rotors - A-OK.  Front
brake pads appear to be OK - worn a little but still should have plenty
of life.  However, the rotors have little grooves worn in them that I
can feel if I run my finger over the surface, whereas the rear rotors
feel absolutely flat and smooth.  It's nothing like what happens when
you wear through a brake pad - I've seen that before.  Is this just
a symptom of the front brakes doing more that 50% of the work, or is
there something wrong with the rotor or brake pad?
