I'm still having problems with my 93 Bronco's intermittant brake pedal siezing for 2-3 seconds upon coming to a stop (makes stop lights interesting when you least expect it). I've replaced pads, rotors, calipers, front ABS sensors and the master cylinder. My next try is going to be a complete brake fluid pruge. Would opening up all the bleed valves at once and pump it dry be the best way to go, or do them like a regular bleed procedure? I'm hoping this will cure the problem, as my next point to check is going to be the power assist, and I hear those are pricey.
Thanks for any help,
Brian

 

Don't "air out" your brake system - '93-96 Broncos have a 4WABS pump assembly that's hard to bleed once air gets into it. Stop buying parts and diagnose it methodically: start with the basic mechanical & hydraulic components to find out exactly where the problem is occurring - it could be a worn 39¢ plastic bushing in the pedal mechanism. If it's not mechanical, proceed to the electronics.
