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.
The RV-12iS can be equipped with Wheel/Brake assemblies made by Matco or Grove.
The Matco wheel can be identified by a hub assembly that bolts to the wheel halves.
The Grove wheel assembly has integral hub halves on each wheel half like other
traditional light aircraft wheels.
Refer to the Matco or Grove manuals and the KAI to identify the individual parts of the
brake system.
• NOTE: This maintenance manual is intended to be used in conjunction with
the RV-12iS Kit Assembly Instructions (KAI) when completing maintenance or
repair processes.

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-12iS 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.
