Brake Maintenance - Cirrus SR22 Pilot Operating Handbook

Cirrus Design
SR22
• Do not "ride the brakes". Pilots should consciously remove
pressure from the brakes while taxiing. Failure to do so results
in excessive heat buildup, premature brake wear, and
increased possibility of brake failure or fire.
• Avoid unnecessary high-speed taxiing. High-speed taxiing may
result in excessive demands on the brakes, increased brake
wear, and the possibility of brake failure or fire.
• Brakes have a large energy absorbing capacity; therefore,
cooling time should be considered. Energy absorbed during a
few seconds of deceleration can take up to an hour to dissipate.
Always allow adequate cooling time after brake use.
• Allow a cooling period following a high-energy braking event.
High-energy braking can include an aborted takeoff or the
equivalent energy required for a Maximum Gross Weight full-
stop from 70 knots in less than 1000 feet.

Brake Maintenance

The brake assemblies and linings should be checked at every oil
change (50 hours) for general condition, evidence of overheating, and
deterioration. Serials 0002 thru 3450 before SB 2X-05-01: At every
annual/100-hour inspection the brakes should be disassembled, the
brake linings should be checked and the O-rings must be replaced.
Refer to Section 8, Handling, Servicing, and Maintenance for specific
servicing information on the Brake System.
