Like the title says, looking for a place that charge for a decent price and preferably 714 area.

Thanks in advance.

I called some places in OC the only one that will turn them is SaddleBack Auto

$20 per rotor

Some shops will not turn drilled and slotted rotor due to cracking on the slots after they are turned. If they are warped some say to drive hard do a hard brake then slowly relies the brake pedal while you are doing a slow roll. That might help if they are warped. But if they are warn down past Factory Spec get new ones.


also did a fast google search and found some good info

Most places don't like to turn drilled/slotted rotors, because its a risk to thier tools. Every time the tool passes over a slot or hole, it can hook, and break the cutting tool on the lathe, or even worse, it can break the lathe itself. This is why a lot of shops don't like to do it.

"Warped" rotors are rarely actually warped, and I mean VERY rarely. Generally it is one of two things, either uneven wear on the rotor, resulting in varying rotor thickness, or uneven transfer of pad material to the rotor face, again, also resulting in varying rotor thickness.

When you get your rotors turned, try to have it done by a place that can turn both faces of the rotor simultaneously. This way you know that both faces are true to each other. If they are done seperately, you can have two flat rotor faces that aren't parallel, and still have a thickness variation, which means you will still have that "warped" rotor feeling.

Most brake lathes have dual bits on each side...
Unless you are using the brake drum bit which is single bit there should almost always be two, one on each side.
and yes you can cut drilled and slotted rotors.
slow cut and new bits for best results.
"Warped" rotor surface runout.
