Brake q's

[anjieandjohn]

I was driving my truck last week and everything seemed to be working great. I had just replaced my front pads and things were good. I didnt drive her again for about 5 days...not unusual when I am on leave since I drive the wif's car. I got in to head back to work and noticed a nice air pump sound when I pressed the brake pedal. Also, it seems that my pedal gets harder and harder to push...It works once then might go 3 or 4 times and be harder than hell to push then work, etc. Any suggestions? I can stop but my right leg is starting to get good workout and it is getting tired.....

Thanks in advance
