Zinc-coated gray cast iron keeps it cool under hard braking and fights corrosion behind the wheel. It's a direct-fit replacement built to get your brake pedal firm and quiet again.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eHere's a straightforward replacement front brake rotor from Hella, part number 355122592. It's a vented, one-piece disc measuring 312 millimeters across the outside diameter, with a 25 millimeter nominal thickness and a 65 millimeter height. If your current rotor is worn past spec, scored, or warped enough to send a pulse through the pedal, this is the kind of direct-fit part that gets you stopping clean again. Brakes aren't the place to cut corners, and a fresh rotor is one of the cheapest ways to restore full stopping confidence.\u003c\/p\u003e\n\u003cp\u003eThe vented design matters more than people give it credit for. A vented rotor has cooling passages cast between the two friction faces, so it sheds heat far faster than a solid disc. That's what keeps your braking consistent when you're loaded up, towing, or working down a long grade. Heat is the enemy of any brake system. When a rotor can't dump it fast enough you get fade, and fade is when the pedal goes soft right when you need it most. A 312mm vented disc gives you real thermal headroom to work with.\u003c\/p\u003e\n\u003cp\u003eIt's a one-piece casting in gray cast iron, which is exactly what you want in a daily-driven brake rotor. Gray iron has natural damping that keeps noise and vibration down, and it wears predictably against a fresh set of pads. Hella finishes the whole rotor with a zinc coating, the hat, the edges, the vanes, all of it. That coating fights the surface rust that blooms on a bare casting the first time it sees rain or a car wash. The friction face wears clean under braking, and the areas the pads never touch stay protected and looking sharp behind an open wheel.\u003c\/p\u003e\n\u003cp\u003eThe mounting side uses a 10 x 112 millimeter wheel bolt pattern with a 65 millimeter hub size. Those numbers are how you confirm fitment before you order. Measure your old rotor, or cross-check the part number against your vehicle's application data. It's sold as a single rotor, so if you're doing the job right you'll want two to keep both sides of the axle matched. Replacing rotors in pairs is just good practice, even when only one side looks bad.\u003c\/p\u003e\n\u003cp\u003eInstallation is standard front-disc work if you've done it before. Pull the wheel, unbolt the caliper and bracket, slide off the old rotor, and clean the hub face so the new disc seats flat. A high spot from old rust between the hub and the rotor is a common reason a brand-new rotor reads as warped, so take a minute to wire-brush that surface. Fresh pads are always a smart move with new rotors so both surfaces bed in together. And go easy on the brakes for the first couple hundred miles while everything mates up.\u003c\/p\u003e\n\u003cp\u003eA quick word on the numbers, because fitment is everything with brakes. Outside diameter is 312 millimeters. Nominal thickness is 25 millimeters when new, and every rotor has a minimum thickness limit for safe use, so measure yours at each service and replace it before it drops below that mark. The height, sometimes called hat height, is 65 millimeters, and the hub bore is 65 millimeters. Match those to your car and the 10 x 112 bolt pattern lines up with your studs.\u003c\/p\u003e\n\u003cp\u003eThis is a replacement-grade rotor built to get a road car or light truck back to a solid, quiet brake pedal. It isn't a drilled-and-slotted track piece, and it doesn't need to be for street driving. If you want dependable stopping, corrosion resistance you can actually see, and a straightforward install, this Hella rotor covers it. Check the dimensions against your application, order a pair, and you're set.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e312 millimeter outside diameter vented rotor for strong heat dissipation and fade resistance under hard or repeated braking\u003c\/li\u003e\n  \u003cli\u003eVented one-piece cast design balances cooling airflow with quiet, predictable wear\u003c\/li\u003e\n  \u003cli\u003e10 x 112 millimeter wheel bolt pattern with 65 millimeter hub size for direct-fit replacement\u003c\/li\u003e\n  \u003cli\u003e25 millimeter nominal thickness gives usable wear life before the minimum limit\u003c\/li\u003e\n  \u003cli\u003e65 millimeter height (hat height) matched to original rotor geometry\u003c\/li\u003e\n  \u003cli\u003eGray cast iron construction dampens noise and vibration at the pedal\u003c\/li\u003e\n  \u003cli\u003eFull zinc coating protects the hat, vanes, and edges from surface rust and corrosion\u003c\/li\u003e\n  \u003cli\u003eSold as a single rotor, so order a pair to keep both sides of the axle matched\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Hella Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eIs this rotor vented or solid?\u003c\/summary\u003e\n    \u003cp\u003eIt's a vented rotor.
