Well when this snow melts my first order of business is to get my trailer brakes squared away. I moved up to a 290da and will be trailering it. The current set-up is surge brakes. I want good brakes and braking ability while backing down the ramp. I am considering adding a elec/hydraulic unit (Brakerite) and bypassing the surge brake actuator. I have also been checking out electric brakes. I see Fulton has electric brake assemblies for boat trailers. They say they are completely waterproof and saltwater tested ( I am in freshwater )This is appealing to just replace the entire assembly on four wheels and have new pads etc. for what a elec/hyd actuator is gonna cost me. Anybody have electric brakes on their trailers ? I will be trailering about every week April - Sept. Thanks for any info.
