Brake Confidence Check - Inflight (Brake-By-Wire), ctd.. AFM 3-05-40
After a minimum of ten (10) seconds has passed:
3. Left And Right Brake Pedals (Pilot Or Copilot) ................................
.............................................................. INDIVIDUALLY DEPRESS
A. Confirm applied brake pressure proportionally tracks brake
pedal deflection.
B. Confirm brake pedal deflection does not cause applied pressure
on opposite brake.
4. BRAKE NUTCRCKR ORIDE Switch............................... RELEASE
If check is satisfactory, proceed with normal landing.
END
Uncommanded Applied Brake Pressure - Inflight
(Brake-By-Wire) AFM 3-05-50
1. Brake System Test (BITE) ............... PERFORM SEVERAL TIMES
IN ATTEMPT TO CLEAR UNCOMMANDED PRESSURE
If pressure returns to normal, perform Brake Confidence Check
- Inflight (Brake-By-Wire), page EB-3.
If pressure remains, proceed as follows:
2. BCS CHL #1 Circuit Breaker (CPO, A-2)................................PULL
The ANTI-SKID FAIL message will illuminate on CAS. Apply
brake pressure for thirty (30) seconds. Open-loop pulsed (BANGBANG)
braking will occur. Release brake pedals.
If brake pressure returns to normal:
A. Reset BCS CHL #1 circuit breaker. If pressure remains
normal, perform Brake Confidence Check - Inflight (Brake-
By-Wire), page EB-3.
If applied pressure remains:
B. PULL BCS CHL #2 circuit breaker (CPO, B-2.) All four (4)
brake system messages will illuminate on CAS.
If brake pressure returns to normal:
C. Leave BCS CHL #2 circuit breaker out and perform Brake
Confidence Check - Inflight (Brake-By-Wire), page EB-3. If
Brake Confidence Check is satisfactory, land with BCS CHL
#2 circuit breaker out.

Uncommanded Applied Brake Pressure - Inflight (Brake-By-Wire),
ctd… AFM 3-05-50
If uncommanded pressure remains:
D. BCS CHL #2 Circuit Breaker (CPO, B-2) .....................RESET
3. ANTI-SKID................................................................................ OFF
Cycle the affected brake pedal(s) in an attempt to clear the
uncommanded pressure.
If pressure returns to normal:
A. If pressure returns to normal, land using the applicable ANTISKID
OFF BRAKING procedure contained in this section.
If uncommanded applied brake pressure remains:
4. ANTI-SKID..................................................................................ON
Assume uncommanded applied brake pressure will be present
during landing. See Landing With Applied Brake Pressure
Indicated (Brake-By-Wire), following this procedure.
END
Landing With Applied Brake Pressure Indicated
(Brake-By-Wire) AFM 3-05-60
1. ANTI-SKID..................................................................................ON
2. Brake Accumulator Pressure ............................................3000 PSI
3. AUX Pump............................................. ARMED (NOT RUNNING)
On Touchdown:
4. Reverse Thrust........................................APPLY AS NECESSARY
5. Rudder and/or Nose Wheel Steering ...............................................
.............................USE TO MAINTAIN DIRECTIONAL CONTROL
6. DO NOT attempt to use brakes.
7. When ground speed is less than 80 knots, use the metering
parking brake to stop airplane.
CAUTION: ANTI-SKID PROTECTION IS NOT AVAILABLE.
SEE THE APPROPRIATE BRAKES SYSTEM PROCEDURE IN
THIS SECTION.
A. Pull parking brake handle up approximately 1/4 - 1/2 inch.

B. Wait for braking action to commence. Increase brake handle
travel as required.
C. As the airplane decelerates, modulate (meter) the parking
brake pressure as required to prevent sudden stopping or tire
skidding.
END
Uncommanded Brake Pressure During Landing
Rollout (Brake-By-Wire) AFM 3-05-70
1. Reverse Thrust ....................................... APPLY AS NECESSARY
2. Rudder and/or Nose Wheel Steering ...............................................
.............................USE TO MAINTAIN DIRECTIONAL CONTROL
3. Discontinue any attempt to apply brakes - FEET OFF THE BRAKE
PEDALS.
4. REAPPLY brake pressure after one (1) second.
5. If the uncommanded or undesired Brake Pressure is still present
and airplane cannot be controlled, DISCONTINUE BRAKE
