The main wheels have standard brand 500x5 rims, six-ply
rated 5.00-5-tyres with tubes, according to FAA Standard
TSO-C62. Cleveland 40-151 wheels with 30-164 brake
assemblies are used. The main wheels are covered with glas
fibre designed fairings of which Figure 4 shows the layer
sequence.
The tailwheel consists of a 5 inch tire and an aluminium rim.
The Cleveland design features an external brake in which
the disc is external to the wheel with the brake caliper
floating over the disc.
The brake system (refer to Figure 5) consists of a brake
assembly located at the inner side of the wheel, a master
cylinder (1) at the rear rudder pedals each, and a brake fluid
reservoir (2) mounted at the engine side of the firewall. The
particular parts of the brake system are interconnected by
brake lines consisting of aluminium tubes and flexible
hoses (A-F). However from Serial No. 22 the brake lines in
the cockpit area are replaced by a KNAPP hose system.
