Review on Wilwood 120 8373 PS 1 Right Caliper by John Langdon

These are larger PS 1 piston calipers with brake line connection with M10 1.25 banjo bolt and M8 1.25 threaded mounting holes. These are great little calipers, they are very stiff and have great brake feel as the caliper doesn't flex like some other Wilwood calipers. They use semi-metallic pads that provide more stopping power, comparable to most PowerSports brakes. The illustration of this Revain caliper is correct, the inlet and outlet bolts are on the right when looking at the caliper from the mounting side.
