My motor only sucks 9" of vacuum at idle, and even with 2 reservoirs I have brake troubles sometimes. Can I switch to manual brakes and still maintain my ABS. I can't afford to put a vacuum pump in yet.
I'm thinking what's needed is a larger piston in the master cylinder or more leverage at the pedal, assuming you've done the basics like bleeding the system and installed a quality set of pads. Note if you're using NoiseStop or PrettyWheel brake pads you're not getting maximum brake force.
ABS shouldn't come into question, I don't reckon. All it's interested in is the brake line pressure, it doesn't care how that pressure is created.
It's a neat question. I hope you can get more discussion going. Good luck.
Actually, I have a set of Hawk brake pads from Steeda. I have a vacuum gauge hooked up to my reservoirs. If I have 16" of vacuum, then the brakes work great. But if it drops down to 9", then they don't work so well. I know that they make manual brake conversions for older fox stangs. You pretty much just change the master cylinder. In theory, it should work the same on an ABS car.
