If you or your techs have the tools and experience shouldn't be a problem. Something that obscure would not do well around here. Do they drive different?

| Don't have any but one of the cons would be always having to remove the wheels, so the calipers can be removed, before the hubs can be removed. |
Why yes, the ORIGinal CHARGER is a Fastback |

| I'm not getting the life out of our drum breaks like I would like my drivers are just driving the buses to hard with a 4 tier route. What Ive read on them there supposed to last longer 100k warranty on the rotors and I want to say 60k on the pads from what the salesman said. |

I see that as an advantage over drum on my hyd. disc. I don't like pulling the hub and having to replace the wheel seal every time I want to check the brakes. Plus having to clean all the oil off and making sure no contaminates get in there. |

We just delivered our first one to a customer. I have 2 more on order for a different customer and one on order for stock. Not enough miles on any of them yet for real world experience but the one I drove did seem to have a more positive feel in the braking.
There is some interesting service info available here

The disc brakes don't have any advantage in this regard. My point is a leaking wheel seal on a drum brake unit can be replaced by simply removing the hub cap, cotter pin and spindle nut and removing the entire tire/wheel hub assembly. And, air drum brake lining can easily be checked with out pulling hub or drum. In addition most air brake drums are "outboard" mounted and can be slid off the hub after removing the wheels. |

OK, I follow. Air disk were being used 25 plus years ago. I just wonder why they haven't really caught on. |

We have 39 C2's with 4 wheel air disc. The 2012 models had some issues with calipers sticking, rotors warping. I've been told that there was a design change in the new calipers. So far the 2013 buses have had no issues.
Pro's:
Stopping distance decrease
Brake pad inspection thru the wheel
Change out pads in 10 minutes.
Con's:
$2,000 initial cost
Can't think of anything else. |
