Title: Brake rotor resurfacing Post by: Galactica on March 24, 2025, 03:18:31 PM Does anyone know of, or can recommend someone who can resurface the rotor from my 1975 CB750?

Title: Re: Brake rotor resurfacing Post by: Galactica on March 25, 2025, 09:07:29 AM Damn the torpedos. I did a bit of reading about resurfacing these rotors. It seems you only get about 20 thou to remove from each side. And because of the hard stainless material, it’s recommended to grind rather than turn. So I bit the bullet and ordered a new rotor. Could have saved some $ by ordering through the US and shipping to a US address. But considering current border issues, the ship $ saved wouldn’t be worth the hassle. And I’ll have it in hand from the Ontario supplier early next week.

Rotors on modern bikes are much thinner than older ones, 4.5mm vs 7mm.
