For removal of the brake cylinder turn out bolts of its fastening to a brake board. Clear details of oil and dirt. Measure the sizes of a brake drum and compare them with given in подразд. "General information".
Assembly make as it should be, the return to dismantling. Upon termination of assembly remove air from system of a hydraulic actuator and adjust a drive of the parking brake.
