I changed oils from STP detergent 30w to Shell Rotella-T 15w-40 and developed brake band chatter at the end of a stop.... switched back and the chatter is gone.

Also, the brake felt more responsive with the 15w-40.

Doesn't this suggest the 30w is lubricating better? I have Kevlar bands.

I think it suggests that you need to put brakes on your wheels!

Any oil guys out there?

My understanding is that a 15w-40 is actually a 15 weight oil with modifiers added so that it behaves more like a 40 weight when it's hot... like adding cornstarch to a gravy.

I have used the shell 15w40 but started using 5w30 in everything after reading on here. It seems most people on here are of the opinion that any modern blend is better than the oil from back in the day. Tim

Wendell,

I had that happen too in my '21 Roadster. Someone suggested, (based on his experience), to use synthetic oil. As he said, it took a while to settle down, but after a while the chatter went away.

Your braking habits can help too. As the car slows, nearing a stop, try backing off some on the brake. You don't need to hold the pedal down in a constant position until coming to a dead stop. Also, as you're slowing to a stop, periodically let off the brake pedal then re-apply. This lets oil onto the band and drum to keep things cooler and reduce the chance of burned oil glazing onto the band lining.
