One brake locks up!

[motownbob]

I have a shorelander trailer,had one wheel cylinder replaced last year, the other the year before. the trailer is a dual axle with one set of brakes. When i go to get the trailer to put the boat on, one of the trailer brakes is locked up, and i have to crack a fitting to release it. This Brake NEVER locks up with the boat on the trailer...What would be causing this? Bob

Rust in the drum.

Leaky grease seal may have contaminated the brake lining.

1 More Idea,.......<br /><br />When you Park the Trailer,...... Make Sure the Last Motion is in a forward direction,......<br />That way the Brakes are Released,+ in a Relaxed position,......<br />That way,.. They Shouldn't Hang Up.......

If one of the wheel cylinders leaked brake fluid on a shoe, that will cause a shoe to stick to the drum.

If you have to crack the fitting to release it, the system must be pressurized.<br /><br />Crude build up - change the fluid and give the system a good bleed through.
