Rev. 2
7-2
OVERVIEW
The brake system includes the necessary components to provide directional
control and stopping ability while taxiing. The left and right brakes are independently
controlled hydraulic disc brakes. The fluid reservoir supplies the master cylinders with
hydraulic fluid. Pressure applied to either brake pedal causes the master cylinder to
force hydraulic fluid through the plastic and aluminum lines to the corresponding brake
caliper.
Refer to the Matco instructions and the KAI to identify the individual parts of the brake
system.

SERVICE
Use of the proper hydraulic fluid is necessary for proper operation of the brake
system. It is good practice to replace the hydraulic fluid every 5 years. If any indication
of contamination is present, replace hydraulic fluid as soon as possible. Since the
brakes on the RV-12 are relied on for part of the airplanes steering control on the
ground, any detected leaks should be repaired prior to further flight. Refer to the service
schedule checklist for component service frequency.
