Abstract
A parking brake used on the tongue jack wheel of a boat trailer to keep the boat trailer from moving is disclosed. The parking brake attaches to a trailer tongue jack wheel assembly that is standard on most boat trailers. The disclosed brake replaces chock blocks so those do not have to be transported with the trailer.

A trailer parking brake for securing a trailer with a tongue jack and a wheel assembly, comprising:
- a brake base for the trailer parking brake;
- a first brake armature and a second brake armature, where the first brake armature and the second brake armature are in communication with the brake base,
- where the first brake armature comprises:
- a first substantially straight side portion and a second substantially straight side portion on either side of the first brake armature and a first substantially semi-circular portion along a top edge of the first brake armature joining the first substantially straight side portion and the second substantially straight side portion;
- and
- a first connection slot within a body of the first brake armature and a first retaining slot disposed along an edge of the first substantially semi-circular portion, where the first retaining slot impinges into the body of the first brake armature to form an aperture within the first brake armature, the first connection slot configured to receive a first connection bolt for securing the trailer parking brake to the tongue jack, the first retaining slot configured to receive the first retaining bolt;
- and
- where the second brake armature comprises:
- a third substantially straight side portion and a fourth substantially straight side portion on either side of the second brake armature and a second substantially semi-circular portion along a top edge of the second brake armature, joining the third substantially straight side portion and the fourth substantially straight side portion;
- a second connection slot within a body of the second brake armature and a second retaining slot disposed along an edge of the second substantially semi-circular portion, where the second retaining slot impinges into the body of the second brake armature to form an aperture within the second brake armature, the second connection slot configured to receive the second connection bolt for securing the trailer parking brake to the tongue jack, the second retaining slot configured to receive a second retaining bolt;
- a trailer brake pad in communication with the brake base, where the trailer parking brake is in an upward position when the trailer brake pad is in a disengaged position, and the trailer parking brake is a downward position with the trailer brake pad in communication with a surface to secure the tongue jack and wheel assembly from movement.
