lone star parking brake block off

[hd400ex00]

i thought i read some where on here that the lone star parking brake block off plate did some harm to the brake system some how i have one on my 400ex and when i took the brakes apart the pins (pistons) were froze in their solid and i was just wondering if that caused that and i should get a new block off.
thanks in advance
