Here are a few helpful hints that will help you lubricate your drum brakes properly.
  1. Don't ever put lubricant on the inside of the drum where the shoes/pads contact the drum.
  2. Use lubricant on the backing plate.
  3. The adjustable star-wheel that separates the shoes can be prone to freezing, so it should be lubricated.

Hereof, how do you stop rear drum brakes from squeaking?

How to Stop Brake Squeal

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

Subsequently, question is, do you grease the back of brake pads? yes, its true, although your brakes will most likely become noisy and "chatter" from vibration under moderate to heavy braking. I use brake grease on the back of my pads. You'll want to grease your slider pins while you're there so you'll need the grease anyway.

Simply so, why are my rear drum brakes squealing?

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.

Drum Brake Lubrication Points

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.

What do bad drum brakes sound like?

Scraping noises when brakes are pressed
Another symptom commonly associated with bad brake drums is abnormal sounds. If the brake drums become excessively worn, they may give off a scraping or scratching sound when the brakes are depressed.

What causes brake drum noise?

Reason 1: The brakes are worn out.
This causes the pad and the rotor or drum to become hardened and shiny, which in turn causes noise. Low pads can also make the wear sensor on many pads contact the rotor, causing a high pitched squeal. If the brake pad material is completely gone, this will cause a grinding noise.

Why are my brakes grinding after new pads?

New brake pads are a bit stiff and need to be broken in. But this noise should lessen as you drive your car and allow the pads to become worn in. There is Debris on the Brake Pad or Rotor. Another reason why your car may be grinding is that there is debris on your brake pad or rotor.

When should drum brakes be replaced?

The brake drums on your car are built to last for about 200,000 miles. In some cases, the drums will wear out sooner due to worn out internal components that put more strain on the drum. As your brake drums begin to wear down, they will actually become smaller.

Do drum brakes make noise?

Answer: 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.

Why are my rear brakes grinding?

Common reasons for this to happen: Worn Brake Pads: Obviously, the most common potential problem here is worn out rear pads (or shoes if you have drum brakes). If you notice a loud grinding sound, it could be the metal backing plate from the pads making contact with the rotor.

Do drum brakes have wear indicators?

A brake lining wear indicator is attached to a drum brake shoe backing plate adjacent the brake lining. The indicator provides a visual gage dimension that assists in the determination of when the brake linings should be replaced.

Can brake dust cause squeaking?

The metal particles in the brake pads will cause squeaking when they rub against the metal brake rotors, which is normal. Also, normal brake function causes brake dust to accumulate which can lead to squeaking. This should quiet those brakes for you. Regular wear will eventually do the same trick.

Can I use lithium grease on brake calipers?

White lithium is a low-temperature grease that can be used to lubricate drum brake hardware and backing plates, but lacks the heat-resistance for front disc brake applications. Brake lubricant can also be used to dampen vibrations between disc brake pads and caliper pistons.

What is the grease for that comes with brake pads?

Often, a small packet of graphite-based grease will come with the brake pads. Apply this to the clips of the new brake pads to keep them from squeaking, as shown in the photo above. This photo shows that the new brake pad has a riveted-on shim, which is the thin metal plate.

Can you use normal grease on brake pads?

Brake grease can also be used to dampen vibrations between disc brake pads and caliper pistons. But, it should not be applied between the pad and any noise suppression shims that may be used. In fact, ordinary grease may cause serious problems if it is used on brake hardware or hydraulic components.

Where do you put anti squeal on brake pads?

You put anti squeal paste/brake caliper lube on the back side of the brake pads where they would make contact with the caliper and where the ears of the brake pad come into contact with the caliper bracket.

Can I use brake cleaner without removing wheel?

What happens if you don't grease brakes?

Squealing noises are the most common symptom of missing shims and grease. However, you may experience other symptoms too, such as bad brake response or a pulsating brake pedal. This is due to the brake pads not being properly aligned with the brake calipers.
