Moishe, nothing is as sad as installing new rotors out of a box and feeling a pulsing brake pedal. Back off they come and go to a taller de torno...
Chuck them up in a brake lathe and take the first cut...

Obeying rules for minimum acceptable rotor thickness is essential. If I had to guess I would say 80+% of the brake rotors used in the USA are manufactured in Monterrey Nuevo Leon.
I have also purchased remanufactured calipers that spec'd out as superior to new OEM. Stainless steel sleeves and teflon seals. This stuff was for one ton and larger USA vehicles. Try $65 US for a Ford F-450 front brake rotor and hub.
There are just as many bad mechanics in Mexico as there are in the USA.
