9000 Aero L4-2290cc 2.3L DOHC Turbo EFI (1996)
High-Pressure Pump
The high-pressure pump pumps brake fluid from the brake fluid reservoir through the supply hose to the bottom part of the pressure accumulator.
The pump, which is resiliently mounted in the hydraulic unit, operates at a pressure of between 140 bar (2030 psi) and 180 bar (2610 psi).
As a safety feature, the pump incorporates a relief valve having an opening pressure of 210 bar (3045 psi) which dumps the pressure to the suction
side of the pump.
Electric Motor
The electric motor which drives the high-pressure pump is turned on and off by the pressure switch and is connected by means of a 2-pin
connector.
Supply Hose
The supply hose connects the brake fluid reservoir to the high-pressure pump. At the pump the hose is connected to an angled plastic union.
