Rear brakes not working-- why?
The front brakes seem to work well, but the rear's just don't seem to be doing anything. I took at look at the rotors last time I was filling up my car with gas and noticed the passenger side rear rotor was completely rusted with zero score marks from the pads (like its been just sitting undriven for weeks/months), and the drivers side rear rotor barely had any score marks either. But the fronts looks normal. So when I drove out of the gas station I stopped with the ebrake a few times and it started breaking off some of the rust and cutting in the rear rotors again. What's going on here? Do I just need to bleed my brakes (my guess is its something with the proportioning valve)?

Re: Rear brakes not working-- why?
did you bleed it properly at the time when u did the conversion.try bleeding the brakes first. its good to know that you don't need to replace anything, but my next guess if that doesn't work would be some seized pistons in your caliber. i did a rear disk brake conversion without having to change the prop valve(even though i will soon), but there is no problem with my brakes not engaging.i figure as u said you pulling the hand brake makes contact then to simply put it, hand brake is like a manual way to engage the rear brakes. hope im making sense to you, im not very good at explaining the concepts of how things work. good luck

Re: Rear brakes not working-- why?
^ My question is for my 99 Si, which came with rear disk brakes (I really should get a signature line or something). I don't think it is a seized piston because the brakes engage when I pull the hand brake and disengage afterwords. Last time I seized a piston it didn't do anything but sit there with the pads engaged against the rotor (so it was basically like driving around with the handbrake on all the time and using the hand brake did nothing). Any other ideas of what would cause this issue?

Seized slide pins and dirt in the anti-rattle clips will cause similar symptoms, but the parking brake shouldn't work either. rear flex lines could be bad I suppose and ballooning out when you depress the brake pedal.
