Front Dual Pin Floating Caliper

Fig. 1 A.T.E. (front) dual pin floating caliper disc brake. Front wheel drive models:

The single piston floating caliper disc brake assembly consists of the hub and disc brake rotor assembly, caliper, shoes and linings, splash shield and adapter.
The caliper assembly floats on two rubber bushings riding on two steel guide pins threaded into the adapter. The bushings are inserted on the inboard portion of the caliper. Two machined abutments on the adapter position and align the caliper fore and aft. Guide pins and bushings control caliper and piston seal movement to assist in maintaining proper shoe clearance. All braking force is taken directly by the adapter.
