>what do u mean by type as oppose to manufacturers?
Type is the design or style of the breakers, specifically, how it attaches to the bus.
> What is BR and BRD
Two of the many Types of breakers.
>I measured the existing breakers and they are one inch so i know i need this size.
Most are that size. half-inch and one-inch are very common.
But that doesn't tell me much of anything about the Type except that they are not half-space breakers.
Without seeing your breaker, I cannot tell its Type.
