Default Another cracked booster

I can't believe how cheap these boosters are being made.
Bought in June 17 and it already cracked. Even the more expensive
Ones look the same. Mabry I am over tightening. Any ideas?

I too went Thru a few, What I Found was is the Master needs to Slide onto it's Studs with Little to no Force, Then tightened to Snug Uniformly and a final Equal Tighten I am sure there is a Torque Spec. for it and I can't recall it now and don't have the FSM with me now

Ok Update, I checked in the FSM Looked at the Master to Booster Torque Less than I Expected 13 lb. ft. same for the bolts inside thru Firewall
