This TRQ brake caliper is a direct replacement for your Ram ProMaster's front left brake system. Compatible with 2014-2020 ProMaster 1500, 2500, and 3500 models with heavy duty brakes, it comes complete with the mounting bracket so you have everything needed for installation. The caliper features high-temperature EPDM seals and boots that resist thermal deterioration better than standard components. The electrostatic high heat powder coating provides rust and corrosion protection, extending the life of the unit. With two pistons (50mm and 52mm diameter) made from steel and cast iron construction, it delivers reliable stopping power that matches OEM performance. TRQ calipers are 100% new components - no remanufactured parts or core charges to deal with. The package includes all necessary hardware and abutment kits for a complete repair. Perfect for DIY mechanics or professional shops working on ProMaster vans used for delivery, conversion, or work purposes. Installation is straightforward if you're comfortable with brake work, and TRQ provides excellent DIY videos to guide you through the process. Always recommended to replace calipers in pairs and install new brake pads and rotors at the same time for even wear and optimal braking performance. The quality is impressive - these feel solid and well-made, not like cheap aftermarket parts that might fail prematurely.
