. That is Ron Russell , he owns Titan Performance Braking and sells and installe the Titan Disc brake systems on all trailers.. He can and will answer any and all questions about the subject...
If I had that choice , even if my warranty was to be voided, I would do it... Warranties are only 1-2 years, disc brakes are forever.... I made the swap and it was night and day....
If you want, you can PM me and I can send you all his contact info...
On edit-- I believe his complete disc brake kits are around $1800.00-$2000.00 shipped to your door... Depending on where you live, and his travels , he can also arrange for the install... I had a local weld shop who builds custom trailers do my install...it was less than $1000.00
