ADVICS Brake Master Cylinder P/N:BMT-125
Keep firm, responsive brake pedal feel on your 2003 Lexus RX300 [All] with the ADVICS New OE Brake Master Cylinder BMT-162 (also written BMT162). The master cylinder converts the force from your brake pedal into the hydraulic pressure that operates the vehicle's brake circuits, and this ADVICS unit is a direct-fit replacement built to OEM specifications for that application.
Note this listing is the master cylinder only — reservoir, brake booster, push rod, dust boot, gasket/seal, bleeder screw, bleeder hoses, mounting bracket and mounting hardware are not included. If a failing master cylinder is the cause of a sinking or spongy brake pedal, replacing it with BMT-162 restores the correct component; diagnose the cause before ordering.
