I have metric GM calipers on my rear end and have ran new 5/16" steel lines to the rear and plan to use -4an fittings to the block. I had a few tell me that 5/16" would have a pressure drop to my calipers, that I should use 3/16" line to run back to them. Has anyone had experience with running these line sizes??????

Thanks Randy :confused:

I just used the stock lines for my rear disks, they work fine!

I'm using rear disks off a 77 Caddy Fleetwood!

Thanks Bill for the reply!! I switched over to 3/16" lines. I was having trouble getting fittings to match up with what I needed and had 3/16" on the brain anyway. I ended up with braided line from the frame to the axle and braided from calipers to the 3 way block..

Thanks Again graemlins/beers.gif
