59 Ford T-bird rear brakes lock

Rear drum brakes lock when warmed up. It’s had two new masters, two new boosters, front disc conversion, new brake lines, new wheel cylinders, new shoes and shoe adjustment. Master and booster came as combo unit w/ front disc conversion; manf. stated pushrod was already pre-adjusted. Brake pedal and brake light switch have been adjusted multiple times.

The MC and booster are aftermarket. Only other remedies I can think of are e-brake cables, new shoe hardware. Anyone else have any thoughts?
