As I took my boat out to the lake this weekend, only about a 3 - 4 mile drive, I noticed my engine temp gauge was pegged. Pull into the launch area and see smoke coming from left rear trailer tire. It appears that the surge brake locked up on just this one wheel. (I should mention this is a 2004 EZ loader dual axle trailer)<br /><br />After letting things cool down and refiling the radiator with coolant on the truck I put the truck in reverse, all sounded good. Put it in drive and could hear the same trailer tire squeel.<br /><br />I back up a little, put it in drive and hit the gas hard to release the surge, or at least I hoped.... After that all seemed to be OK.<br /><br />My questions are, what would have caused the break to lock on this one wheel? Shouldn't it have locked on both the left and right side? <br /><br />Is this a serious issue that I should take up with EZ loader or a somewhat common problem with surge brakes?<br /><br />Anything I should look for? I have a 3 hour trip I was planning on taking this upcoming holidat weekend and don't want to have this happen again? Any info would be greatly appreciated....
