So, I need a new master cylindar for my 2 ton chevy . It has sat in a barn 4 several years. So when i replace it and if I find the hydrovac if it isn't any good
can I do away with the hydrovac ? Are they a burger of rebuild? Or can I update with something newer?


I just finished a 1946 chevy pickup street rod
now on a 1950 chevy 3100
.
also a GMC 220 with duals
and a 1948 chevy 2 ton
