Default New Cherokee owner with a few questions

Hello I recently got a 89 Cherokee 4.0 auto and so far I love it it has 176k on it and alot of suspension work as far as lifted locked built in air compressor where the a/c compressor was, anyway there are a few questions I have on issues with it that I have noticed.

1, The brake light comes on even though there is fluid in the master cylinder it will come on when I am at a light for a while and it wil stay on any ideas?

2, The master cylinder is new yet the brake pedal is kinda of stiff and the braking is pretty poor it likes to creep forward at a red light unless i feel applying more and more pressure

3, It cranks for a while before it starts first thing i the morning or if it has been off for a while. I just replaced the crank position sensor but it didn't help at all.

If I could just get some hints on where to start off it would be a great great help thanks everyone!!

Sounds like you might have a vacuum leak going to the brake booster.

As for # 3 read this... https://www.cherokeeforum.com/f51/cr...x-tips-153657/
