Brake booster check valve for the Nissan S14 Silvia SR20DET. This one-way valve is used in the brake booster vacuum circuit to help retain vacuum in the booster and prevent reverse flow when intake manifold pressure changes.
A suitable replacement to consider when inspecting the brake booster vacuum system for a leaking, damaged, or malfunctioning check valve. Inspect the associated vacuum hoses and connections as part of diagnosis; a hard brake pedal or loss of assist can have more than one cause.
- Listed application: Nissan S14 Silvia SR20DET
- Part reference / SKU: 47478-03B00
Confirm part number, hose connections, and valve orientation against your existing setup before ordering. Compatibility with S15 Silvia, other chassis, or modified vacuum systems should be verified separately. Install in the correct flow direction and have brake-system work performed by a qualified technician.
