Coach 410, 1995. Rockwell ABS Disc. Uneven wear on front pads noticed when the ds wheel bearing replaced. Later had shop inspect. Slide pins were sticking on ds. Both sides: Replaced brake pads (Air Disc Brake Pads D268- #3832, Van Horn Truck Parts), turned rotors, cleaned and lubricated slide pins. 

Yea. Ready to go. Headed to Nova Scotia from Abilene. Terrible brakes. The upside is that it reminds you to look farther down the road, keep Jake ready and ensure that your personal gastrointestinal evacuation is up to date.

Hard stop (ok, Attempt at hard stop) required huge brake pedal pressure. Locked up tag disk. Still missed the turn, yet had an opportunity to replace tag tires due to huge flat spots. 

After 5,000 or so miles, back in Abilene. Brakes getting less effective. Had to go to Houston. Great practice driving in heavy traffic with small amounts of braking. PS, front began providing all the work and producing stink bombs and heat to indicate their efforts. DS taking a break.

Now my request: The Rockwell ABS discs, as described by my mechanic, utilize a standard brake air piston actuator, then through a concentric arm (similar to drum actuators) push on an acme screw to transmit pressure to the brake pads. Supposedly, this was an older approach utilized on heavy aircraft brakes. 

In other words, these do not utilize air caliper assemblies. 

I am taking in for another inspection, Monday. 

Any comments would be greatly appreciated.
