Help me figure out brake issue...

I installed new rotors and new pads but after 20-30 miles, I checked the rotor and noticed this line/groove in the rotor - normal or not?

 

Light scratches and shallow grooves are normal after use and won't affect brake operation.

Deep grooves - over 0.015-inch (0.38mm) deep - require disc removal and refinishing or replacement.

That it is the threshhold where brake pads set in the rotor. If you notice grooves above that line then you need to replace the rotor or have it resurfaced.

 

Oh, OK, so that line is normal then. Thanks!

 

i had a line on mine last night when i rebuilt my front pass caliper.
