trailer brakes out

[Drew00]

hey everyone, i'm new to the site and figured that you all might be able to help me out. my brakes on my tandem axle dorsey trailer are out. i found that the line running from the master cylinder to the drums has a leak, none of the exposed lines are leaking. i can't physically see the leak, its inside the tubing of the trailer, but when i added brake fluid it started leaking at the back of the trailer where the tail lights are. i called dorsey and they told me to replace the brake line and i should be fine. my question to you is have any of you all ever done this before. and if you have was it easy to do. i looked at it and it doesnt look too hard. i ordered to part from dorsey and it should be here by the end of the week. thanks for any help.

Shouldn't be too difficult. When you get the new line take it to an auto parts store and purchase a coupler (double female) that fits the line. Take the old line loose at the master cyl. and the axel then attatch the new line to the old with the coupler and use the old line to pull the new one through the frame.

First let me preface this with if you haven't worked on brakes before this might be important, if you have this is second nature.

When you get the new line on take the extra time and loss of brake fluid to make sure you prime the brake lines properly. I'm not sure what type of brakes your trailer has, eg electric or pressure sensitive, but bleed them until all air is gone from the new line and then bleed them alittle more. You will be much happier from day one if you don't have air bubbles in the line.

Both ideas are great, you also want to blow out the lines befor hooking them up to get out any junk. As for bleeding you may want to rebleed after first use just to be sure but is not a must. One big thing buy a big jug of brake fluid so you dont run out.
