Had a gent purchase a rear disc conversion and install it, still complained about crappy brakes not working well with his 33's. I was unaware of the reason for the purchase until after he had also purchased a Super 16 kit, installed it, and then couldn't get the rig to stop. Phone and email went back and forth for months until finally I had him swing by. When it got here and I was going to take it out for a test drive, I hopped in, foot on the brake pedal and fired it up. Rock hard pedal. Didn't even bother backing it out, just pulled it in, swapped in a new booster and then went and did a break in on the kit. It would smoke those 33's if you just looked at the pedal funny. Couple of weeks later, get a call, the brakes suck. Alright, bring it by and we'll look at it. Go do a break in again, working perfectly. That repeated several times even though after the first time I had him drive while I watched. 30 mph, he starts lightly applying some brake a half a block away from the stop sign. I explain he can't do that, it will never work. Several times of him swinging by so we could break them in later, I told him I would swap the kit for the 15", no charge, so at least that way it had a slightly better chance of staying broken in. Either that, or he could work on trying to fix his braking habits. Nope, that's how my daddy taught me and I'm not changing and I don't want a smaller kit. Ok then, you do you, but I'm done breaking them in because you have too big of a kit.
Factions aren't good for any group.
