How do i bleed these trailer brakes? Surge disc, tandem axle. I've cleaned all bleeder valves, have the mityvac hand pump but they still aren't grabbing!!!
When you open the bleeder on the caliper it will collapse the tongue just like when you open the bleeder while holding pressure on the brake pedal of the car. So the trailer would roll a couple inches and you'd have to move the tow vehicle to extend the tongue again.Shooting from the hip here. Could you keep the brakes actuated by being on an incline then bleed each hub? Making sure to top off as the fluid gets replaced?
This ^^^^^ or the UFP type actuators have a whole in the bottom that allow you to pump the brakes using a big screw driver.if you have a receiver hitch, just put it in the coupler & use it like a brake pedal. run a hose from the bleeder into a jar with a little fluid to cover the end, keep your eye on the master cylinder level and pump until clean, air free fluid fills the jar.
