Hello Al, I have not had to do a refirb on my M17 trailer, but I did rebuild my M23 Trailrite, including brakes and surge master cylinder, an outfit here in Mpls called Pioneer Wheel had everything I needed. Every item was on the shelf, no backorders! Bones ____________________________________________________________ Looking for insurance?
