Nissan Micra Brake Master Cylinder Exploded Diagram & Torque Specs (BR-7)

This document is a single page (BR-7) from a Nissan factory service manual brake section, showing an exploded parts diagram of the brake master cylinder assembly. The illustration identifies all major components: reservoir tank, reservoir cap, seal, O-ring, oil strainer, float, connector, stopper cap, primary piston assembly, secondary piston assembly, and the inner kit assembly (which must be replaced as a complete kit). A cross-sectional view of the assembled master cylinder shows the fast-fill valve, which is marked "Do not disassemble." Two torque specifications are given: the hex nut at 8-11 N·m (0.8-1.1 kg-m, 5.8-8.0 ft-lb) and the brake tube fittings at 15-18 N·m (1.5-1.8 kg-m, 11-13 ft-lb). Assembly notes instruct the technician to apply brake fluid or rubber grease to sliding contact surfaces when assembling the master cylinder, and to check parts for wear or damage and replace them if any such conditions are observed. The figure reference is SBR811. A reader can learn the component breakdown for disassembly/reassembly, which parts are serviced only as a kit, which valve must not be disassembled, and the correct tightening torques.
