This design is common for many Ford Transit models, providing both braking and parking brake functionality in one component. The rotor’s 12.126-inch outside diameter and 1.303-inch nominal thickness deliver a substantial braking surface area, while the discard thickness of 1.181 inches indicates when the rotor should be replaced to maintain safe braking performance. The vented construction helps dissipate heat during braking, reducing the risk of brake fade under heavy use.\u003c\/p\u003e\u003ch2\u003eSpecialty - Street Performance; S-Groove Technology Line\u003c\/h2\u003e\u003cp\u003eThis rotor is part of the Raybestos Specialty - Street Performance; S-Groove Technology line, which focuses on delivering enhanced braking performance for street-driven vehicles. The S-Groove design aids in improved pad bite and helps channel away dust and gases generated during braking.
