It is leaking fluid causing the brakes to stop working after a day or two it is a small pump with 4 flared lines coming out of it and brake fluid is leaking i dont know what its called or if there is a gasket available that i can replace can you tell me what it is ? Its not coming out of the master cylinder or booster its a small black pump on the driver side behind the radiator.

Sounds like a hydraulic brake modulator valve for the abs system. Most likely the piece is not repairable. Take a close look. Maybe the leak is coming from a brake line at the modulator and not the mod. itself. Also if the mod. needs replacing it may require the use of a scan tool to properly bleed the brake system.
