MAINTENANCE MANUAL EXTRA 330LX
32-40-00 WHEELS AND BRAKES
General
This chapter provides maintenance personnel with neces-
sary procedures to accomplish both on-aircraft and off-
aircraft maintenance of Cleveland design wheel and brake
assemblies. Such maintenance shall include inspection, re-
moval, servicing, refinishing, and installation of assemblies.
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
carbon fibre designed fairings of which figure 5 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 4) consists of a brake
assembly located at the inner side of the wheel, a master
cylinder (1) at the front and rear rudder pedals each, and a
brake fluid reservoir (2) mounted at the engine side of the
firewall. The master cylinders are mounted in line, so that the
front cylinder looses his efficiency, when the rear cylinder
has been actuated. The particular parts of the brake system
are interconnected by brake lines consisting of aluminium
tubes and flexible KNAPP hoses.
The tail wheel has no brake.
I M P O R T A N T Test brakes after maintaining the brake system. Actu-
ated brakes shall keep the aircraft standing with en-
gine running at 1.800 rpm and maximum propeller
angle of attack. With applied brakes and powersetting
above 1800 rpm the wheels may slide on grass.
N O T E For further information concerning main wheels and
brakes refer to Cleveland Wheels and Brakes Compo-
nent Maintenance Manual AWBCMM0001 und
Technician's Service Guide AWBTSG0001.
