Hey Lyn

[KevinP]

I know you handle UFP but my Brakes are by TIE DOWN. (Ranger Trailer). Dealer installed. I just had to replace my master cylinder and my selenoid had failed twice. Trailer is only three years old. Stored indoors. What could be causing this?

[Lyn O. Dyer]

Usually contaminated brake fliud is what damages the master cylinder, or towing alot with air in the lines,it's only a piston with a rubber cup that goes back and forth. The soleniod is just a valve that opens and closes, very simple, and it's usually a bad ground that keeps this from working. You should contact Tie Down about this.

Last summer when dealer replaced soleniod he didn't tighten down the nuts. I had brake fluid all over my driveway. I refilled the resevoir, with brake fluid #3 but didn't bleed the lines. That may have done it.
