Brake Caliper Bolts

[Brodz]

So I was driving tonight and heard something fall off my car and the result was a horrific screeching metal to metal sound when i put on the brakes. Bf had a look and I've lost one of the bolts on the front left wheel that holds the brake caliper on. Anyone know the length of these bolts? I need to replace it asap as there's no way I'm driving the car without it.

pull the other one out shoot down to repco etc and get a new one (not driving your car of course)
