Various applications :
Serie 1 80" "and Minerva : front left brake cylinder. The diameter of the entrance hole for the pipe is smaller than that of the original cylinder. Must therefore mount it with the brake hose (SF-219824) specially designed for installation. Caution before ordering! Measuring the diameter of the hose entry hole in your brake cylinder. If the diameter of the hole input for the tip is 10.5mm, the brake cylinder is still the original. So you have to order one brake cylinder + 1x SF-219824. If the diameter of the entrance hole the pipe is +/-8.3mm, the brake cylinder is no longer the original model, so you only have to order the cylinder (no need to order extra SF-219824).
