For the moment it's just tucked into the pocket in the cab behind where the bracket was located. I'll probably just use adhesive cable tie mounts. It's a lightweight plastic module. Doesn't really need much.

The A1 trucks also have the exhaust brake. I don't think pad life was the concern. The military would rather have stopping power - they have enough problems with accidents to worry about brake pad life.

I didn't really notice that.... not sure by what mechanism that would be the case. You sure you're not just getting used to how much effort it takes? I know that I certainly did over the last several years. At any rate the A0/A1 pedal valve assembly takes a fraction of the pedal effort. You...

I can only subjectively tell you it's an absolute game changing difference. I can add that I own a performance shop with a chassis dyno so I'm not unfamiliar with exceptionally good brakes. The Saturday dyno rental today was an Infinity Q50 that made 715 rear wheel HP. Trust me you want this.

Just an update on this. I've got about 400 miles on the new/old WABCO pedal valve (rebuilt it prior to install) and it works GREAT. Honestly it has totally changed the confidence level I have in the brakes. They went from kinda scary at high speed (can do 80+ MPH with the ECO Hubs), to VERY...

I measured both of the assemblies pivot to actuator rod/roller and both were close to 1.5" but the Bendix is slightly larger I think.

Those of you who have not driven an A1R or A1P2 probably will not understand this post. The C7 trucks (serial #100,001+) including both A1R and A1P2 have a different air brake pedal valve and if you have driven A0, A1, and A1R you may have noticed that the A1R trucks seem to have a brake pedal...
