Aircraft
After landing on Runway XXL in ZZZ with my student; the airplane lost the differential braking hydraulic system on the right side; going all the way to the left unable to stop the airplane to maintain centerline. Finally; I cut the mixture to stop the airplane getting into the grass next to taxiway Delta. The incident was reported to Ground Control who assisted me at all times. No damage was reported.
Cessna 152 instructor pilot reported a braking anomaly after landing; causing the aircraft to nearly exit the runway surface.
