PUP hydraulic brakes

[Griegox]

I use to have a PUP with electric brakes and was very happy with this setup. We now own a Jayco Eagle that has a hydraulic brake which is connected to the hitch. When I first bought this trailer the brakes did not work and I found it was because the fluid leaked out. I repaired the leak and now the brakes work great. The problem is the brakes work too great. After a short time of driving the brakes seem to lock up causing the PUP to jump at every stop. Any help would be appreciated. My only thought is that there is too much brake fluid in the system.

Hi have you check the shoe ? might try backing the brake shoe off just a little and see if that helps.

Have you bled the system?  If the system was dry then there is prob air in the lines.

Thank you all for your input. I did bleed the brakes but will go through them again this week. Thanks Fly for the technical page. Very good info.

If the brakes needed bled then they wouldn't hold well at all. It sounds like the shoes are adjusted to tight.

I don't know how air in the lines would cause this, sinces that makes for a spongy pedal/soft brakes in cars, same goes for trailers.
I also would suggest adjusting the shoes in a few clicks if the are grabbing too much.

My Dexter Axle manual has alot of good information/explanations in it.  There's a trouble shooting guide for Hydraulic Braking Systems - and, while you have hydraulic brakes, if the trailer brakes are too aggressive - you need to reduce the gain setting on the in-cab electronic brake controller.  (Dexter recommends the Predator E/H electro/hydraulic brake controller)

There's also information on adjusting the drums, etc.
