intermittent brake light
Car is a 1988 Pontiac Trans Am GTA. It has all wheel brakes and I recently replaced the prop valve and did the master cylinder this past spring.
For the last two days I have seen something weird. If I step on the brakes hard enough, the brake light comes on. It only clears this issue when I step on it again hard enough. I haven't gotten a chance to troubleshoot properly, but I can say that when I replaced the prop valve, i did get air in the system which I bled. However I didnt do it correctly and had air at the calipers. Did it again and it was fine until now.
Suggestions??

Re: intermittent brake light
Sounds like you're still pushing air around in the system.
Re-Bleed the system.
Start at the right rear, left rear, right front, and then left front. Make sure all your fittings are tight and insure reservoir stays full while you and a buddy re-bleed.
