Instruction:

1.Remove the road wheel, brake disc and brake calliper from the vehicle. Next remove the calliper mounting bracket, in some vehicles the calliper mounting bracket is a cast part of the hub.

3.3 Using the other hole on the alignment plate as a guide, drill out the damaged thread using the stepped drill bit (fig.1.4). Continue drilling all the way through, using the larger diameter on the drill bit to enlarge the bolt hole so a threaded insert can be used.

Note: Use some thread lock on the threaded insert.

3.5 Slide the washers and roller bearing (fig.2C) over the calliper bolt then insert into the drilled out hole then screw into the new insert. Tighten the locator to seat the new insert fully home.
