Long story short, I've been having persistent problems with my disc brakes binding. Have replaced pads, checked calipers, bled lines well (I think!) Noticed the emergency lever on my actuator was messed up, had slid down and was no longer functioning, so decided to just replace actuator. The one on the trailer was a Titan that according to the manufacturer is for drum brakes. I suspect the previous owner retrofitted discs on the trailer and kept the old actuator. My question is - will an actuator that the manufacturer says is for drums work properly on discs? The rep at Titan was somewhat vague, the rep at Southwest wheels where I bought a new disc only actuator says a drum actuator would put out too much pressure for discs. So, what to do? My life would be simpler if I could just replace the existing actuator with an identical one, but if it might be the cause of my problems to begin with I'll deal with it...
