Brake caliper bolt sizes

Hi went to change my brake pads today and managed to round off one of the caliper bolts, does anyone know the size of the caliper bolts? I can't remember if they are both the same size or not. Cheers

The main (big) ones that hold the caliper carrier to the strut? They are a funny extra-fine-pitch M12, M12x1.25 I think. (M12 is normally x1.75, fine being M12x1.5)

Best bet is to get another Toyota one to make sure it's a high-grade, new is probably not going to brake the bank and far cheaper than finding a normal M12x1.25 bolt or damaging the threads on the carrier.

If you're feeling extra keen pick up an M12x1.25 tap and clean the threads in the carrier, you'll be amazed at the difference, you'll be able to wind the bolts in/out totally freely like new.

Double-check the thread against the new bolt / tap etc using an existing bolt though just to be safe. :)
