These design elements help to evacuate gases, dust, and water from the braking surface, improving brake pad contact and reducing fade. The black zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps dissipate heat generated during braking. The rotor's nominal thickness is 22 mm, with a discard thickness of 20 mm, indicating when replacement is necessary to maintain safe braking performance. The rotor features a directional surface type with both slots and drilled holes, designed to optimize braking efficiency and reduce brake fade under demanding conditions.\u003c\/p\u003e\u003cp\u003eThe rotor's hat is finished with a zinc black coating to resist rust, while the disc surface has a plain finish. It includes four bolt holes with a bolt circle diameter of 100 mm and a center hole diameter of 55 mm, ensuring proper fitment on compatible Scion models. The overall diameter measures 255 mm, and the height is 43.3 mm, matching OEM specifications for the Scion xA and xB.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eImproves braking performance on Scion xA and xB vehicles\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during extended or aggressive braking\u003c\/li\u003e\n\u003cli\u003eHelps prevent rust and corrosion on rotor hats\u003c\/li\u003e\n\u003cli\u003eEnhances heat dissipation to maintain consistent stopping power\u003c\/li\u003e\n\u003cli\u003eAddresses brake noise and vibration issues related to worn rotors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed on compatible Scion xA or xB models using the correct torque specifications for the four bolt holes. Verify that the rotor thickness is above the discard thickness of 20 mm before installation. The directional slotted and drilled surface should be oriented according to the vehicle manufacturer's recommendations to maximize performance. It is advisable to inspect brake pads and other braking components during rotor replacement for optimal results.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 633-91002L rotor to meet or exceed OEM standards for fit, form, and function.
