brakes....

[6768chevylover]

Okay let me tell you what I'm experiencing.. Every once in a while when I come to a stop I feel like I have manual drum brakes(if you understand that).. I have a 71 blazer with power brakes. Everything is new for brake oriented except for booster and proportioning valve. The calipers are the wildwood replacement calipers... Like I said it seems when I come to a stop it seems to keep rolling even if I press on the pedal harder.. Scares me sometimes. Any Ideas what it might be? Thanks, Mike Happy Holidays!
