How do you know when its time for a seal kit on the brembos? And, if say I did need it, how much are they at the stealership?

 

Are they leaking fluid? If not then you're good.

Inspect the dust boots as well. If the caliper isnt leaking, sticking, and the boots look good, then no rebuild is needed. The rebuild kits of for the non-brembos are $40 per caliper. I imagine the Brembo kits are double that.
