to all: i am in the proscess of replacing all the brake components on my 66crown. so far, 3 of 4 wheel cylanders have been replaced and the 4th is in the wings along with the master. i am also replacing all the flex hoses. here is the problem. I can not break lose the fitting between the front brake lines and the old flex hose. i have removed the horse collar and the line is loose from the wheel cylinder (both front lines were rotted through and fell apart when i played with them). it is (or was ) a 3/8 fitting and i have been holding that with an open end and using the wrench on the 5/8 brass fitting of the brake hose. i say was. because they are now rapidly beginning to round out. liquid wrench has not helped and i am afraid if i keep cranking on these,,that i will end up breaking the fitting or the line itself. is there a secret to this or is my 66 just being unfriendly? mark truman
