Squeaky drum brakes?

Seems my rear brakes make irritating squeaking noises when pressing and releasing the brake pedal. Parts are all in good mechanical condition.

Is there some sort of lube that needs to be on the pivot points or what?

Thanks

 

Yeah, there should be a little lube on the contact points between the shoes and backing plates, and on the links that go between the wheel cylinder pistons and the shoes.

Lubriplate or something.

 

Sometimes the brake shoes can become glased and can squeal on first application. Its like the surface of the brake shoe and drum become highly polished and there is a noise that comes from them - Does it squeal under pressure or just on light application? If its the latter then this could be your issue.
In the past we used to rough up the shoe and the drum with a bit of course sandpaper to get rid of the "glase" and let them resettle into a different wear pattern

 

I can sit in park and duplicate the noise when pressing the brake pedal.

Mainly I was looking for advice on what to put on the pivot points.

Whatever I use, I would imagine it would need to have a very high melt-point since the brake parts would see a good deal of heat generated by friction.

 

This is what I use
No. 110 Brake Lubricant

This water repellent grease is designed for the contact points where the brake shoes rest on the backing plate and for the automatic adjusters inside the brake ***embly. Part No. L0037-

 

And there it is.... the answer.

Thank God for the internet, and the Big Block Ford.....

 

That probably IS the answer but when you pull those drums, make sure to check your return spring arrangement/ configuration. Sometimes springs or other parts get "crossed" and rub on each other.

 

I had all the brakes apart for refurbishing two winters ago.

Just this summer it started with the squeaking.

I'll probably grease all four corners in the near future.

Yes, I still have drums all around, and the car stops just fine. (no brake booster either)

 

Make sure your brakes are adjusted. That can cause them to make excessive noise. On your backing plates, there are raised areas that the shoes ride against, those need a dab of brake grease on them. The anchor at the top needs it too as well as anywhere there is metal to metal contact.

i have used the crc brand brake lube. you also might want to take some emery cloth to the high points, usually 6 on bendix brakes. don't forget the anchor pin area, the edge of the shoe moves there.

 

Get some louder mufflers?

 

Well... I certainly enjoyed the sound of my car last Spring with open headers (as I was trying to idle over to the exhaust shop).

But I'm pretty sure nobody else in town really cared for that racket!
