In addition, the system must of course be checked for leaks, but this would be noticed during the change.

Last night I did flush the system with new fluid but still have some air in the system after 2 bleeding sessions(we didn't do the inside bleeds) going to bleed again tonight.

But we did also get the car in the air and in nuetral and confirmed that the front right wheel is hard to move and the caliper might be partially engaged or seized. Im thinking the partially engaged caliper overheated the old fluid and boiled the brakes. The brakes felt fine last night on a quick test drive on the street before we flushed with new fluid.

The current plan is to change the master cylinder(might as well idk when it was changed) and rebuild the calipers. Want to try to get it back to the house tonight though if we can get it bled all the way. Going to take off caliper tonight as well and just pull the pads and have a look at the pistons/clean the pad tracks.
