Integrated lift axle suspension system and method of use

A lift axle air suspension assembly for wheels on a vehicle, the lift axle air suspension assembly comprising:

• a lift axle cross support member that is adapted to mount to the vehicle;
• a first end and a second end of the lift axle cross support member;
• a first bracket operatively connected with the cross support member and located proximate the first end of the cross support member;
• a first beam pivotably coupled to the first bracket, wherein the first beam pivots about a pivot axis located between a forward end and a rear end of the first beam, wherein the first beam is adapted to couple with a first brake assembly for a first wheel;
• a second bracket operatively connected with the lift axle cross support member and located proximate the second end of the lift axle cross support member;
• and
• a second beam pivotably coupled to the second bracket, wherein the second beam pivots about the pivot axis located between a forward end and a rear end of the second beam, wherein the second beam pivots independently of the first beam, wherein the second beam is adapted to couple with a second brake assembly for a second wheel;
• wherein the operative connection of the first bracket and the second bracket with the lift axle cross support member is adapted to improve load distribution of the lift axle air suspension assembly.
