UFP DB-35 vs. DB-42

Unique Functional Products, UFP as they are commonly known, offers two different series of disc brakes. They offer a DB-35 and a DB-42 and since the parts are not interchangeable it is essential to be able to identify what you have.

DB-35
The DB-35 visually appears more similar to an automotive caliper.  It will have two mounting ears below the body to attach the caliper directly to the axle brake flange. The rotor is also identifiable but it can be a little more difficult. On the rotor/hub there will be a minimum thickness of 17mm (MIN THK 17.0 MM) stamped  on the inside of the back.

DB-42
The DB-42 is visually unique and consists of a thick caliper body that houses the piston, and a metal shroud that will house the pads. The DB-42 will have only one mounting bolt hole located in the center of the bleeder valve and brake line port. On the rotor/hub there will be a minimum thickness of 22.40mm (MIN THK 22.40 MM) stamped on the backside.
