Why do my brake drums squeak?

Your rear drum brakes squeal for a number of reasons. One reason is brake dust that has accumulated in the brake drum. When you apply the brake, the pads inside the drum come in contact with the brake dust, which causes the squealing. Another cause is the absence of contact between the drum and shoe.

Also question is, how do I stop my drum brakes from squeaking?

How to Stop Brake Squeal

Analyze the brake squeal.
Be sure new brakes are properly bedded.
Install noise-reducing shims on the backs of your brake pads.
Check that your brake pads are not worn out.
Examine the brake pad and shoe linings to see if they are damaged or unevenly worn.
Check the brake pad design.

Subsequently, question is, does brake cleaner stop squeaking? You can buy brake cleaner in a spray can, and spray it on your rotors without any problem. That is what it is made for. It dissapates very rapidly, so it must have some type of solvent in it. For the brake squeal though, they also make some type of lubricant called "Brake Quiet" or similar name/product.

Also question is, why are my new drum brakes squeaking?

Answer: Brake pads are the most likely problem. You probably have rear drum brakes and the noise you're hearing is most likely the brake shoes rubbing the backing plate. This movement is normal but your contact points probably no longer have any lubrication between the shoe and backing plate causing a squeaking noise.

What causes squeaky brakes?

Brake squeal is common and can be caused by a number of conditions: Worn pads, glazed pads and rotors, broken anti rattle clips, lack of pad insulation or insulation shims, and incorrect rotor surface cut or no surface cut at all.
