Brake boil over

Hey guys,

Has anyone experienced losing brake fluid through your master cylinder reservoir caps? Just installed a new manual brake master cylinder and a front and rear disc brake kit from Dr diff. I notice that my brake fluid is overflowing, I’m not sure if it’s because it’s boiling over or if it’s because the cap seals are bad? When the car is on a slight incline/decline/hill/etc… Brake fluid seems to leak from the caps. The reservoir is not overfilled.

My second thought is that the exhaust manifold could be overheating the master cylinder? It looks awfully close.

Anyone ever have a similar issue?
