Disc Brake question
I was tearing apart the 71 front crossmember I bought and both rotors have the same groove on both sides. I thought maybe a po sucked with brakes, but when I was cruising ebay I saw the same thing on other discs. Why is that groove there

Re: Disc Brake question

Re: Disc Brake question
Original 71-72 rotors had a factory groove in them according to my GM parts guy. He told me that the first time he saw my truck, "Your truck still has OEM original front rotors, you can tell by the groove"
Starting in 73, no groove, and all aftermarket replacements are without groove too.

Re: Disc Brake question
Thanks....now I wonder why they put it there? Also with this groove, can they be cut? They don't look too bad, and with replacements at about $70 a piece I might try to reuse mine.

Re: Disc Brake question
My 71 malibu has a groove on the factory rotors. A futile attempt at adding surface area in my estimation.
