The main gear is a tubular steel undercarriage leg surrounded by a full length fairing with a step for access to the cabin. The main gear has a 7 ft 7 in (2.3 m) wheelbase. The nose wheel is connected to the engine mount and has an oleo strut to dampen and absorb normal operating loads. The nosewheel is steerable through 8 degrees either side of neutral and can caster under differential braking up to 30 degrees. It is connected to the rudder pedals through a spring linkage. The braking system consists of single disc brake assemblies fitted to the main undercarriage and operated by a hydraulic system. Brakes are operated by pushing on the top portion of the rudder pedals. It is possible to use differential braking when taxiing and this allows very tight turns to be made. The 152 is also fitted with a parking brake system. It is applied by depressing both toe brakes and then pulling the "Park Brake" lever to the pilot’s left. The toe brakes are then released but pressure is maintained in the system thereby leaving both brakes engaged. The standard tires used are 600 X 6 on the main gear and 500 X 5 on the nose wheel. The engine's power can be increased by various modifications, such as the Sparrow Hawk power package, increasing it to 125 hp (93 kW The disadvantage of the Sparrow Hawk conversion is that it uses pistons from the O-235-F series engine and therefore the engine recommended time between overhaul is reduced from 2, 400 hours to 2, 000 hours.
