How do you fix brakes when you have to pump them twice to get them working?

U dajust the rear Drum brakes if so equipted if it has dsc in the front.

If you mean that your foot goes to the floor without resistance the first time, but not the second, you need to have your master cylinder checked out, and possibly replaced.

I have also seen this problem caused by condensation in the brake fluid caused by old fluid. The adjusting the first poster talks about is only for adjusting the emergency brake *I thought*. I could be wrong on that. you may just need to bleed the brakes and get the air out of the system. the second pump compresses the air and makes pedal hard.
