So was driving home today and every time I would accelerate and then stop right after i would hear a big cluck. Found out the clunk was coming from the front left brake Took my front left tire off to find i had a missing bolt on the bracket that you attach the caliper to. The caliper/bracket had been hitting my rim and then hitting the rotor.

Does anybody know what size bolt I need to bolt it back to the bracket? ( not the two bolts that hold the caliper, but the bigger bracket bolt is what is missing.) Any help would be great guys! Thanks
