Lots of readers but not many posters on this one...
Anyways I finished the install on the weekend. The 10X 2 1/4 brakes fit perfect. The old bolts were a bastard to get off. Could only fit a spanner wrench in there and used a 10lb hammer to get em off. I was close to pulling out the grinder.
I replaced the bearings a few months back (cuz I don't do things in logical order) so they didn't need repack. Added a
light layer of grease to them and the
axle for good measure.
I adjusted the new brakes by tightening until the wheel was resisting movement them backed off till free spin but very
light brake pad / drum rubbing sound. I'll run a few hundred km then readjust after they are properly seated.
Took it for a quick burn and heated up the brakes really good. What a difference! Its like the trailer isn't there when you stop. I went years without trailer brakes, never again.
My other motivation for the brakes was to be able to safely add the
weight for an installed water tank. I'm thinking about 12 gallons. Depending on my motivation I might have it ready for camping season..... Also we are looking at a new phev tow vehicle. The tow capacities on whats available is low and most requires brakes.
Cheers!
