Brake wheel cylinder

Various applications :
Serie 1 80" "and Minerva : front right 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 +/-10.5 mm, 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).
Serie 1 86"-88": brake cylinder front right.
Serie 2 88"and 3 Series 88" until 1980: brake cylinder front right.
Serie 3 88" after 1980 (model with 2 brake cylinders by wheel on the front axle): rear right brake cylinder.
