question on wrench size?


Aug 23, 2008
I would like to do my rear drum brakes. Its my first time. I got new aluminum drums & everything. I think I can do it. Question the brake wheel cylinder on the wheel by the brake shoes, Does somebody know the size flare nut line wrench for the oil line fitting, in the back of the brake cylinder.

Is it a 7/16 flare nut line wrench?
I'll take a Stab at 7/16" too " ???? Get the " 7/16 " - 3/8" Combination Flare wrench .
