From what I understand, Brett is a slime-forming yeast, and that slime is what's difficult to completely eradicate, and as long as there's enough cells in ANY leftover slime residue (inside cracks or inside hard to clean hosing), they can reform a colony. I have a completely different set of everything plastic for Brett (and will eventually use for other sours but Brett's the only one I've used thus far).
I did a tripel mashed at 147, went from 1.085 to 1.013 with WLP500 in during a month in primary, and aged in secondary for about 5 months with Brett B which dropped it to 1.008. No sourness at all, but some leathery/horsey funk in the background.
