The next step is to locate the caliper and bracket so the caliper is straight and square with the rotor. To do this the caliper pads must clamp the rotor. No hand holding here. We brazed a short section of old steel brake line to an air hose fitting. This brake line screwed into a brake flex hose, which in turn installed on the caliper just like stock. I plugged in the air hose. Whoose, bang, clamp. Don't have your fingers in the way. Check the pad position, tapping it gently if necessary. The caliper bracket is now ready for welding. The caliper bolt heads must be sticking out of the caliper. This allows the caliper to move as the pads wear.
Always tack weld a bracket on each side first to lessen the chance of warpage. After tack welding the bracket, I suggest removing the axle for final welding (I just hate to put a lot of heat into a bearing and seal). There were several small triangular brackets in our kit. These are welded in to stiffen the caliper bracket. Since alignment is critical, tack these in place before final welding.
With everything double-checked for position and then tack welded, proceed with the final welds. Once the air hose is removed, the axle should turn smoothly.
