It is built with treated replacement components to support vacuum sealing and pressure transfer, and it is tested before release to confirm function. This unit is a fit for 2002-2003 Toyota Sienna models, and the Toyota Sienna fitment is listed with no position designation.\u003c\/p\u003e\u003cp\u003eBecause the master cylinder is not included, this booster is intended for service jobs where the existing master cylinder is reused or sourced separately. The metal housing, two mounting studs, and standard replacement design make it a direct service part for brake system repair. Part number B3268 should be used when matching the correct booster configuration.\u003c\/p\u003e\u003ch2\u003eUsed For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestoring brake pedal assist when the pedal feels hard\u003c\/li\u003e\n\u003cli\u003eAddressing vacuum loss in the booster assembly\u003c\/li\u003e\n\u003cli\u003eReplacing a worn or failed brake booster\u003c\/li\u003e\n\u003cli\u003eCorrecting inconsistent braking response during normal driving\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify master cylinder compatibility before installation, since this booster does not include a master cylinder.
