All the brake lines on my 55 Pontiac were replaced except for the front drivers side. Went to remove last weekend and the end just stripped at the flex line end. The flex line needed replacing anyway, so I cut it to pull out the wc and take off the backing plate for cleaning and painting. The brake line that connects into the main junction box (no proporioning valve, just a main splitter) was not coming out. Stripped that as well with a flare nut wrench, not much room for a visegrip type tool. Consulted the handy H.A.M.B. archives - cut the brake line at the the top of the nut, pressed an 11MM 6 point socket (1/4 drive) onto the top of the nut with the help of a Knipex plier wrench, and voila, she came off! Off to get a new line this morning and will have that corner completed with all new hardware by end of week. Now, just have to get that brake end out of the socket! Pretty tight - screwdriver and tap out on the vise. Thanks HAMB'ers!
