ADVICS Brake Master Cylinder for Scion iQ

The ADVICS BMT-415 is a standard replacement brake master cylinder built to OE-style specifications for 2012-2015 Scion iQ models. It uses an aluminum cylinder body with anodized and Kanizen-plated surface treatment, plus OE-quality rubber components for consistent hydraulic performance.

Product Details

The ADVICS BMT-415 brake master cylinder is engineered for direct replacement on the 2012, 2013, 2014, and 2015 Scion iQ. It is built with a 20.64 mm bore diameter and OE-style construction to support proper brake hydraulic pressure. The aluminum housing and plated surface treatment help strengthen the cylinder body, while the included reservoir, cap, seal, and sensor support a complete service replacement. This part cross-references Toyota 47201-74031 for the same application.

Common Reasons to Replace

  • Brake pedal feels soft or sinks under steady pressure
  • Visible brake fluid leakage around the master cylinder
  • Internal seal wear causing inconsistent hydraulic pressure
  • Brake warning light related to master cylinder sensor concerns
  • Loss of braking performance from worn hydraulic components

Installation Notes

Before installation, confirm bore size, outlet thread size, and sensor connection match the original unit on the vehicle. Bench bleeding is recommended after installation to remove trapped air from the hydraulic circuit. Mounting hardware, brake booster, push rod, bleeder screws, and bleeder hoses are not included, so reuse or source those items separately as needed.

Quality Assurance

ADVICS supplies OE and OE-style brake components, and this master cylinder is built to the same application-focused standards used for original equipment replacement. The anodized and Kanizen-plated cylinder body, OE-quality rubber components, and included seal and sensor support dependable service on the Scion iQ platform.
