Pull the pads and check the surfaces for rivets (if the grooves are at the
same spot on each rotor) that are poking through the pad surface. You never
know if the guy making the pads had a bad day and used ones too long or
something. Do they even use rivets anymore? The pads I have (new) that I
just looked out have a 4 "plug" looking things on the back that are flush with
the surface. Looks like they are holding that pad to the brake pad.
If the grooves in different spots maybe the pads are good at picking up rocks
and you have forsaken all odds and gotten a rock stuck in the pads on both
sides at the same time.

Subject: Problem: Grooving brake rotors
The front brake rotors on my TR250 are developing grooves very quickly -
like
10 miles after brand new. The rotors just removed had only a few hundred
miles on them and a deep (looks deep, probably 1/16) about one third of the
way out from the center. One groove. Matching hump on brake pad. Both
front
rotors. Installed new rotors and new pads. Same problem starts.
Any ideas? Planning to change calipers.
Anybody else experience this?
