I have a 2006 LSV, it came with the boatmate trailer, I live on lake so I have only used trailer maybe 4 times. One brake caliper has the brake pressure applied. I am trying to move trailer. Question is their any way to manually release the caliper. I know about the safety lanyard on trailer that applies brakes in emergency ,and I also know the trailer won't back up without the backup clip or trailer liters hooked up. Any help would be great.
