I have seen many posts about air packs failing after a short life.
I have not really seen posts about the best ones, which is what I want.
I rebuilt mine but the hydraulic cylinder was badly pitted; I honed the crap out of it and then polished it with 600 grit and washed it, but it seems to be sticking whenever I slam on the brakes (as a test in case of emergency). Pushing the brake pedal somewhat slower than normal gives a normal brake application. I disassembled it a second time to check for wrong assembly, damaged new parts, and even blew thru the hydraulic to make sure the check valve was working correctly and it does.
It did not do this before, so either I screwed up the assembly (twice, while referring to the TM page-by-page), the cylinder is no longer the correct dimension and is making the piston cocked in the bore and sticking, or some other problem.
The master cylinder is new as of today and made no difference. I am using fresh DOT5.
I will be buying a new air pack.
Any recommendations, or warnings about suppliers?
P.M. me if you don't want to publicly call out anyone.
Thanks. Need this done, got several shows and parades in the next couple months.
