LEARJET 20 SERIES PILOT TRAINING MANUAL
BRAKES
Parking Brakes
On SNs 23-003 through 23-049, the parking
brake can be set only by the pilot. Fluid reserve
chambers in the parking brake valves cause diffi-
culty in parking brake release. Depress the ped-
als slowly while holding the PARK BRAKE
handle in the off position.
Antiskid
Model 23 and SNs 24-100 and subsequent are
equipped with the Goodyear antiskid system. The
system operates as described earlier in the chap-
ter, with one exception—model 23 airplanes do
not have ANTI-SKID GEN lights; model 24-112
and subsequent do have the lights.
