Again, thanks! | | | | Joined: Sep 2012 Posts: 103 'Bolter | | 'Bolter Joined: Sep 2012 Posts: 103 | Ok So I have Bendix 3 3/8 disk brake calipers all around on my 51 COE. I have 1.25 master cylinder bore mated to a hydroboost. So, My question is what size brake lines do I run from the master cylinder to the distribution block, then from the distribution block to each caliper? Thanks Chris | | | | | Joined: May 2005 Posts: 8,878 . | | . Joined: May 2005 Posts: 8,878 | I'd probably run 3/16 to each front caliper and over the rear axle. 1/4" for between MC and proprotioning valve and to the rear axle.
Use an original modern truck with similar/same components as your guide, what did they use? May as well benefit from GM's engineering. | | | | | Joined: Sep 2012 Posts: 103 'Bolter | | 'Bolter Joined: Sep 2012 Posts: 103 | Grigg, Thanks Thats my next step, trying to locate a modern with like parts Chris | | |
