- Chapter 13: Aircraft Landing Gear Systems › Anti-Skid › Anti-Skid System Maintenance
Reports of anti-skid system malfunction are sometimes malfunctions of the brake system or brake assemblies. Ensure brake assemblies are bled and functioning normally without leaks before attempting to isolate problems in the anti-skid system. Wheel Speed Sensor Wheel ... spinning it by hand or other recommended device to ensure brakes apply and release via the anti-skid system is common practice. Control Valve Anti-skid control valve and hydraulic system filters should be cleaned or replaced at the prescribed…

valve meters hydraulic fluid to the corresponding brake assembly in direct relation to the pressure applied to the pedal. Many power brake system designs are in use. Most are similar to the simplified system illustrated in Figure ... Power brake systems are constructed to facilitate graduated brake pressure control, brake pedal feel, and the necessary redundancy required in case of hydraulic system failure. Large aircraft brake systems integrate anti-skid detection and correction devices. These are necessary because…
- Chapter 13: Aircraft Landing Gear Systems › Brake Inspection & Service › Bleeding Power Brake Systems
hydraulic system should operate without air in the fluid as should the brake system. Therefore, bottom up pressure bleeding is not an option for power brakes. The trapped air in the brake system would be forced into the main hydraulic ... system, which is not acceptable. Many aircraft with power brake systems accept the connection of an auxiliary hydraulic mule that can be used to establish pressure in the system for bleeding. Regardless, the aircraft system must be pressurized to bleed…
