? Differential braking is allowed, but a braked pivot turn is not recommended as a general rule (i.e. braking to fully stop the wheels on one main gear), to avoid stress on the landing gear assembly
? On wet or contaminated runway, more specifically when turning on the runway white or yellow painted marking, tight turn lead to jerky rides of the nose wheel which are noisy and uncomfortable.

For the CM2, the procedure is symmetrical (taxi on the left hand side of the runway).

BRAKE CHECK
Criteria: SA
2 Applicable to: MSN 0045-1718
When cleared to taxi, the PF should set the Parking Brake to "OFF". When the aircraft starts to move, the PF should check the efficiency of the normal braking system by gently pressing the brake pedals, to ensure that the aircraft slows down. The PNF should also check the triple brake indicator to ensure that brake pressure drops to zero. This indicates a successful changeover to the normal braking
system.
BRAKE CHECK
Criteria: P4576, SA
3 Applicable to: MSN 2593-4078
When cleared to taxi, the PF should set the Parking Brake to "OFF". When the aircraft starts to move,
the PF should check the efficiency of the normal braking system by gently pressing the brake pedals.
CARBON BRAKE WEAR
Applicable to: ALL
Carbon brake wear depends on the number of brake applications and on brake temperature. It does not depend on the applied pressure, or the duration of the braking. The temperature at which maximum brake wear occurs depends on the brake manufacturer. Therefore, the only way the pilot can minimize brake wear is to reduce the number of brake applications.

TAXI SPEED AND BRAKING
Applicable to: ALL
On long, straight taxiways, and with no ATC or other ground traffic constraints, the PF should allow the aircraft to accelerate to 30 kt, and should then use one smooth brake application to decelerate to 10 kt. The PF should not "ride" the brakes. The GS indication on the ND should be used to assess taxi speed.
BRAKE TEMPERATURE
Applicable to: ALL
The FCOM limits brake temperature to 300 °C before takeoff is started.
This limit ensures that, in the case of hydraulic fluid leakage, any hydraulic fluid, that may come into contact with the brake units, will not be ignited in the wheelwell.
This limit does not ensure that, in the case of a high energy rejected takeoff, the maximum brake energy limitation will be respected.
Thermal oxidation increases at high temperatures. Therefore, if the brakes absorb too much heat, carbon oxidation will increase. This is the reason why the brakes should not be used repeatedly at temperatures above 500 °C during normal operation. In addition, after heavy braking, the use of brake fans �� can increase oxidation of the brake surface hot spots, if the brakes are not thermally equalized.
