to start first off im running z32 breaks up front and stock s14 rears.
i have a stock s14 bmc.
I changed the rear pads today and after i bleeded them i seem to have this weird problem that i never seen before .
when the car is idle and i break and keep breaking it seems to hesitate a good mount almost feels like it wants to choke the engine. btw im running an s13sr
I WILL ANSWER ANY QUESTIONS thanks.

sounds like you need to clean your idle control valve.

Is that what's pluged in to the bmc? I spilled a little fluid on it. Or any other ideas?

the brake master has a vacuum line that goes across to the intake manifold. make sure that plugged in and check that line for any leaks. the idle air control valve (iacv) gets dirty/clogged and causes idle to bog or die when braking or sometimes just in full stop at idle. might have just been coincedance that it happened after your brake upgrade. a little carb/choke cleaner will do the trick.
