Detailed Product Description
This Dynamite Friction disc brake rotor is specifically designed for use on Cadillac Eldorado and Oldsmobile Toronado vehicles, ensuring precise fitment and optimal braking performance. The rotor’s vented construction allows air to flow between the rotor surfaces, reducing heat buildup during braking. The directional slotted and drilled surface helps to evacuate gases, dust, and water, which can improve brake pad contact and reduce brake fade under demanding conditions.
The rotor features a plain disc finish combined with a zinc silver hat finish that provides corrosion resistance, extending the rotor’s service life. With a bolt hole quantity of five and a bolt hole diameter of 13.17 mm, this rotor matches the factory specifications for the specified vehicle models. The overall height and rotor height of 58 mm, along with the 279 mm outside diameter, ensure compatibility and proper clearance within the brake assembly.
