Picked up a set of Brembos and noticed something inside the thread of the right rear caliper.

For those familiar with taking apart and installing the OEM Brembo calipers:

There is a convex seat that fits into the bottom of the brake line banjo bolt. On all the other three calipers, the seat is intact. In the right rear, the seat is gouged a little, but the opening for the brake fluid is unharmed. It appears that the banjo bolt for the brake line went in too far and damage the seat a little.

Picture for reference:



I'm assuming that that seat and bolt connection is not a perfect seal and that the threads and washers help to seal the system completely.

Do I have reason to be concerned?

 

Bump and dump.
