Highly not recommended. I sent them a master/booster off a 56 Caddy to rebuild....looked beautiful, but leaked brake fluid badly. I drained it, plugged the outlet and packed the reservoir with a rag. They sent it back in a plastic bag drowning in brake fluid. What a mess. Paint running like a girl's mascara everywhere!! I fixed it and re detailed it myself and asked them for some money back. He said no, but I'll hook you up next time. I said if you think there'll be a next time you've lost your mind.
Sorry to hear that - I've used them for over 20 years and never had a bad part, or bad attitude. Although I have used them more for steering gear rebuilds than brakes.
