I've had these brakes on my saltwater trailer for 8 years. 1000 km per year on average. The durability is better than other brands. 2 complaints about the installation. The slide guide pins on 2 of the 4 brackets were mounted to the rear. Had to be properly removed and re-loctite. I also had to bend the 3 guide pin mounts a bit to get a smooth alignment with the caliper. I think the only way to get good permanent alignment is with a molded guide pin brace. These are stamped.
