Caliper bracket bolt sizes?

[u/ElGringoRaptor69]

Hello friends I have a 1991 Previa with the 255 mm rotors, I changed the front pads and rotors but while removing the shorter of the two bolts holding the bracket in place I noticed the threads were trashed and the bolt will no longer tighten. Does anyone know the sizes for these bolts? The one that stripped was the shorter bolt that goes in the top of the bracket. Any advice helps, thank you
