Query: Simply not working above 90 psi

I bought this pump for my bike's 700 x 23 tires which require for my weight a pressure of 115 psi. Shamefully this pump was not able to get air in the tire above 90 psi - even when I put my whole weight on the handlebar (fearful of a serious explosion ;-)) nothing happened.I picked a Topeak JoeBlow Max since I was very happy with a very similar model of the same brand of a friend of mine.
