The rotor’s surface is both drilled and slotted, which helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and reducing brake fade. The rotor has a nominal thickness of 32 mm and a discard thickness of 29.4 mm, ensuring durability and safety over its service life.\u003c\/p\u003e\u003cp\u003eThe rotor’s outside diameter measures 330 mm, with a height specification of 62.8\/66.8 mm, fitting precisely on compatible Mercedes-Benz models. The zinc silver coating on the hat provides rust resistance, extending the rotor’s lifespan in various driving conditions. The rotor features a directional brake surface, which is designed to optimize braking efficiency when installed correctly.\u003c\/p\u003e\u003ch2\u003eAbout the DFC Brake Rotor - Drilled and Slotted - Silver Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors with enhanced heat dissipation and improved braking response. This product line combines drilled holes and slots on the rotor surface to maintain cleaner contact surfaces and reduce brake fade under demanding conditions. The silver zinc coating on the rotor hat adds corrosion resistance, making it suitable for long-term use on Mercedes-Benz vehicles such as the C300, E250, and E300.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during aggressive or prolonged braking\u003c\/li\u003e\n\u003cli\u003eImproves wet weather braking performance by channeling water away\u003c\/li\u003e\n\u003cli\u003eMinimizes brake dust buildup for cleaner rotor and pad surfaces\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent brake pedal feel and stopping power\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion on the rotor hat for extended durability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation direction. Verify that the bolt hole pattern (5 holes, 112 mm bolt circle diameter) matches the vehicle hub. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 29.4 mm. Proper torque specifications should be followed when securing the rotor to avoid warping or uneven wear.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-63117L rotor to meet or exceed OEM specifications for Mercedes-Benz C300, E250, and E300 models.
