Glazed Rotors... got a cure?

[74bigblock]

My front rotors have glazed over with the addition of new pads. There appears to be plenty of meet on the rotor (I will measure), but I'm wondering what the easiest way is to grind off the glazed material and get to some good metal? I would prob just yank the whole spindle to get to the rotors, that way I don't have to drill out the original rivits that are still intact.

Thanks for your input!

My .02. Many say not to replace rotors cause the factory set them up for runout with the hubs attached. But old rotors are old rotors. You can either have them cut to get the glaze off or buy new ones. If they are glazed they aren't going to work properly. You might try emery paper on them to try to develope the necessary cross hatch pattern but I doubt if you will be able to effectively get the glaze off. I just put new heat treated slotted rotors on my '69 cause the old original ones were glazed, pitted and just looked shi**y. I coupled this with new Hawk pads. BIG improvement. I use the '69 alot more than the '67. I've left the original rotors on the '67 but they have have been cut once.

chuck a 3m 2in scotch brite pad in a drill & clean em up,no need to remove the rotors

Are you actually having a problem braking, or just don't like the appearance? If it's the former, all you need is to roughen the surface with a medium grade sandpaper. A sanding disk attached to an angle grinder or drill works best.

No need to have them 'turned' for a minor issue like this. You may want to find out why your pads caused this too.

Yes, the brakes are not performing well and squeeling like a pig being blugeoned to death. I'm sure it was an issue with the interface between the operator and brake pedal durring pad break in.

Dave Take'm to NAPA or a part's store that has a Brake Lathe and have them Turned, Cost about $5 ea. junk!! p.s. Put new Pad's on it Too or the old one's mite still Squeel!!

There should not be a need to cut the rotors on a brake lathe. Two things I ALWAYS do with new pads is to scuff the surface of the pad with a medium sand paper. Then I take a medium grit sand paper sponge (looks like a bath tub cleaning sponge but it has sand paper embedded in it) and scuff the surface of the rotor, lightly sanding it in a direction that is perpendicular to the direction of rotation.

The other thing that has helped me on my Corvette and another car, both with squeeling brakes, is to take the pads out and put a bevel on the edge of the brake pad material. Typically the pad material is made with a nice square cut and then bonded to the metal backing plate. I take my pads and put a 45 degree bevel on both edges and I can almost always eliminate any squeeling.

If I need to have 'em turned, can this be done while on the spindle, or will I need to drill 'em off?

(If I have to drill 'em of, then I might as well spend 120$ and get new ones!)

Thanks

do both sides of the rotors with a orbitial sander to remove the buildup

Dave, Don't forget to Clean and Insp. wheel bareing's and races and Repack with grease!! junk!!
