I'm trying to get some of the play out of the brake pedal since I swapped to disk brakes in the rear. I've heard that FJ 80 master brake cylinders have front and rear residual valves that should help restore proper pedal response. If my Land Cruiser history is correct (which it probably isn't), it seems that 91-92 models were only offered in drum rears. After 92, Toyota switched to the full floating disk brake rear but only offered it with the ABS option. I guess my questions are 1) are non ABS master cylinders from disk braked FJ 80's available and 2) if not, will I run into any problems running an ABS master cylinder on a non ABS toyota pickup?
