I would strongly recommend a complete rebuild of the entire braking system at this point, and don't forget your flex lines, hope that helps. | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | 3B is right on. I would add that if there is no sign of a leak at the wheels be sure to look along the chassis rail for a rusted hole in the line....but 3B's advice is right on. We have to be able to STOP once we get going. | | | | | Joined: Oct 2011 Posts: 118 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2011 Posts: 118 | i will look around and will get back to you...thanks | | | | | Joined: Oct 2011 Posts: 118 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2011 Posts: 118 | i see that they have brake lines already bent to fit truck... wondering if the bends are that close...also would you recommend rebuilding brake cylinder or buying new one...

Pre-bent lines have been good fits on my trucks.
Look at the bores in the brake cylinders. If they are pitted replace them. If they are not pitted, hone and rebuild them.
As mentioned above, replace the three rubber flex lines.
