Just stumbled onto this thread and makes for interesting reading. Will go to Kerry's link in a mo.
I have had one or other of my brakes lock up on no less than 4 occasions in the past 12 months on a trailer that's less than 18 months old. It's a sensa brake system. On one occasion it went in under warranty only to have a different wheel lock a few weeks later when it was out of warranty.
The strange thing is/was that it always seemed to lock up when the rig was in the water ie the trailer was empty. The last time was a real bugger as we couldn't get it down to the water to trailer the boat and it needed many pairs of hands to get it there. Once the boat was on the trailer, it released, although it was smoked up when we got home.
The discussion with the dealership went along the lines of "you'll always have problems with brakes when you're dunking" which was met with my reply that if you're buying a trailer advertised as "drive on" and it is meant to be dunked, then you'd think it should be up to the job without the brakes keep seizing
Anyway, fair go to the dealer who eventually replaced the pistons (pitted)and calipers for free, although it was out of warranty. I shall now have to wait and see what eventuates and whether it lets me down again 'cause I have no option other than to dunk.
I am fanatical about cleaning/rinsing the trailer and particularly the brakes and I always bleed the sensa unit, even when it's parked up at the ramp so I have no idea what was causing the problem
I am not that good with mechanical stuff and it fair pisses me off that owing to my bad experiences, I now wonder just when the bloody trailer is going to let me down again.........rather takes the edge off what should be a pleasurable day out fishing.
Any hints on risk minimising?
cheers
