I bought all new brakes lines and a master cylinder for 51. The lines seem small . I was thinking they maybe gave me the wrong lines . I purchased the parts from the truck and car shop in orange ca. | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | What size truck is it? '51 1/2 tons use 3/16" line for all, 3/4 ton and larger use 1/4" line exept for the line across the rear axle, which is 3/16".

Seems I remember ONE 1/4" line going somewhere on my 52 1/2ton...or maybe I'm just getting old? | | | | | Joined: Jun 2010 Posts: 1,001 Shop Shark | | Shop Shark Joined: Jun 2010 Posts: 1,001 | No, not old, you are correct. The line from the MC to the distribution block (front to rear) on the right frame rail is larger than the rest. | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | The '52 may be different from the '51. The specs I posted are from the '51 shop manual.

Jim Carter most likely has them, but their site is no good with a tablet PC. | | | | | Joined: Apr 2010 Posts: 114 Shop Shark | | Shop Shark Joined: Apr 2010 Posts: 114 | Inline tube.com has nice stainless correct size lines, tees and even nice actual length brake quality cables, compared to other cheap junk out there..... | | |
