Bleeding trailor brakes

Bill from Scotland · Sep 19, 2010

Hi I have a tri-axle trailor made for a CAT compressor/generator which I am converting to carry my Massey 97 and its almost finished except for brakes and painting. It has over run brakes activated by the tow hitch, one brake pipe has a hole. Assuming I replace the pipe how should I go about bleeding the brakes. I thought I might fill the master cylinder behind the hitch with fluid and loosen the fleed screw behind the farthest away wheel then work forward. What I am not sure about is how I activate the system to get out the air, do I have to pump the hitch back and forth? I guess this could be quite hard to do . Any better ideas very welcome.
Thanks
Bill

This link shows screwdrivers used to compress the master cylinder, then bleed as usual.

Not sure if this could work in your application.

The alternate method is to park the trailer with the master cylinder higher than the wheel cylinders and open the bleeders one at a time and let gravity bring the fluid to the wheel. This is the SLOW method, but is an alternative if you don't have help the pump and open and close the bleeders.

lil trick i use on motorcycle brakes will work fine for your trailer...get a new pump oiler can and fill it with whatever brake fluid your brakes take...loosen one bleeder screw about 1.5 turns and use a piece of rubber line to connect nozzle on pump can to bleeder...take cover off master cylinder and pump brake fluid backwards towards m/c...when you dont have anymore air bubbles in m/c resivoir youre done.

use the breakaway lever on master cylinder, it will pump fluid through system and push air out of bleeders

Vacuum Pump hooked to the bleeder screw. Take the cap of the master cylinder. You can buy cheap handheld Vacuum pumps for bleeding brakes and hydraulic slave cylinder's at most auto part stores.

Reverse bleeding is definatly the way to go. There a companys that sell items specific for doing this but can be pricy. Any item you can find to pump the fluid into the bleeder should work. This method works good on hydraulic clutched.
