What size of brake line should be run with this setup? | | | | | Joined: Sep 2013 Posts: 93 Shop Shark | | Shop Shark Joined: Sep 2013 Posts: 93 | Mimic the stock. Drum brakes move more fluid than disc. That is why the rear line is 1/4 inch. Can't go wrong with what the General specified from the factory.

Someone added lines, but I wanted to make certain to run the correct diameter. If I understand your post correct, you are saying the stock lines are 1/4 in., correct? | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | I can't say that GMC is the same, but according to the manual for Chevrolet, the lines are 3/16" except for the line from the MC to the junction block and the cross pipe for the rear axle.
