ABS Electric High Power Master Cylinder w/ Inline Accumulator Diagram #10-56-9
ADS electric high power master cylinder schematic showing brake fluid lines, inline accumulator and wiring color codes.
This document is a labeled installation/plumbing schematic for the ABS Power Brake 'Electric High Power Master with Inline Accumulator' system, firewall mount version, part #10-56-9. It shows a polished master cylinder with ports labeled for the rear brakes and front brakes, an inline accumulator (a black spherical high-pressure accumulator on a manifold block), and an electric pump/motor assembly with a pressure switch and wiring harness with relay. A legend distinguishes the fluid routing: a solid blue line indicates the low-pressure feed from the reservoir to the pump, while a dotted black line indicates the high-pressure line from the pump/accumulator to the master cylinder. Wiring is identified as Black = Ground, Red = Battery Positive, Blue = Keyed Ignition Positive. A prominent warning states that to avoid motor damage, brake fluid must be verified flowing from the reservoir to the pump motor inlet before turning the ignition ON. The manufacturer recommends DOT 5 brake fluid; DOT 3 or 4 may be used but must never be mixed with DOT 5. A high-pressure warning instructs reading the instructions before removing the line or accumulator. The document lets an installer identify component connections, hose routing, wiring hookup, and fluid requirements.
