Matco Brake Caliper
SkyStar Aircraft Corporation
has come to our attention that a slight change in the design of Matco
brake calipers may cause interference between the outboard brake pad of
the #39002 (LBRH-12R) brake caliper (refer to Fig LGH-4 in the builders
manual) and the mounting lugs welded to the wheel for the brake rotor.
Some calipers may also impinge upon the bolts and nuts used to secure
the caliper mounting plate to the landing gear weldment. The caliper
must be able to “float” from right to left during brake operation to
achieve best braking efficiency and pad wear. The above mentioned
impingement may prevent the caliper from floating to it’s extreme
inboard or outboard limit, reducing the effectiveness of the brakes.
inspect your calipers to make sure that they do not hit the lugs on the
wheels, and that they can float to their full inboard or full outboard
positions without any interference from the mounting bolts for the
caliper mounting plate. If there is any interference between the caliper
and either the lugs on the wheel or the bolts on the mounting plate,
clearance may be obtained by grinding the affected parts per the
drawings below. Do not grind the lugs on the wheel any more than is
necessary to obtain .030” clearance between the rotor and to caliper.
