Reddit reviews CRC 05016 Disc Brake Quiet - 4 Fl Oz.

A lot of people seem to misunderstand where break squeaking comes from. It's very rare that the sound actually comes from the contact of the pad and rotor. Rather, the squeak comes from the contact of the pad and the caliper: see image.

Basically, as the brakes rub against the rotor, they like to vibrate and wiggle around a bit, and it's that direct metal-on-metal contact between the backing plate and the caliper that ends up squeaking.

The easiest and best solution is to get some Disk Brake Quiet and apply a small amount of it to the back of your pad where it would normally be in contact with the caliper. This creates just enough of a buffer that the brake pad can shimmy around as it needs to, but won't rub against the caliper and squeak.

FIPG is just RTV silicone, right? CRC makes this stuff which is basically RTV with a funny shaped nozzle on it for exactly this purpose. I've used it and it does stop squeaks, but also is a huge pain in the ass that you have to be careful not to get everywhere and is impossible to get off your calipers.

They sell it in fancy red "made for this purpose".

It’s just a tacky goo that you put on the back of the brake pad (according to the DIY video I watched about a month ago). Stops the inevitable brake squeak

I haven’t tried it but am planning to. I just had my 5000 mile service and asked them to look at it (first Harley) and the brake noise came back louder... so frustrating

This happened in mine too until I changed the brake pads and used this where the pads contact the caliper.

I'm assuming the shop checked to see if the pads were worn? Brakes are designed to screech unpleasantly if the pad is worn out.

If you think the pads are dirty maybe try taking them out and cleaning them off with some brake cleaner and an old toothbrush?

edit: clean the rotor, too.

another edit: some research tells me that some folks have had noisy brakes due to the brake piston rubbing on the metal back of the brake pad. Some people have put a piece of duct tape between the piston and pad, and there is also a product called CRC disk Brake Quiet

most of my cars never ever squeak, i don't do anything at all.

but the one car that did squeak required that i put a silicone type liquid that solidifies in-between the bad and brake piston.

The brake squeal is due to the pad itself vibrating within the caliper. You could always just pop them out, and apply some CRC BrakeQuiet to the back of the pads and pop them back in to resolve it.

I usually grease the following locations:

• Where the rotor contacts the hub
  
  
• Where the wheel contacts the rotor
  
  
• Where the pad's "ears" contact the caliper bracket (It appears that you have clips there. Grease where the clips touch the caliper bracket AND where the pad ears go into the clips.)
  
  
• Where the bad backing touches the caliper. (It appears that you have decent quality ceramic pads WITH shims.) If the shims have adhesive, do NOT grease where the shims attach to the pad.)
  
  It seems you have done all this in your original post... I can only offer two more solutions:
  
  1.) Bed your brakes in hard... Get it on the highway and do a few hard stops from 70 MPH down to 30. This'll heat up the pads and burn off any impurities that may be on the surface of them.
  
  2.) They sell a red goop at auto parts stores. https://www.amazon.com/CRC-Disc-Brake-Quiet-05016/dp/B000CINV88
  Use a thick layer of that to adhere the shims to the brake pad.
  
  You're literally rubbing two chunks of metal together... The brake rotor and brake pads. There's bound to be some vibration. The idea is to minimize that vibration. Usually grease helps stop the vibration from getting from the pads and reverberating in the rest of the front end of the car... The shims and clips act like springs and prevent vibrations. The red goo acts like a cushion and further dampens vibrations.
  
  The squeaking noise is harmless, but annoying. If you can't get rid of it, don't worry too much.

"Disk Brake Quiet" Like this stuff from CRC which I use creates a rubber like film when it dries to stop metal chattering against itself. It is on the pad faces backings and they do not need to move once installed against the caliper bracket and caliper cylinder, so a lubricant is not needed.

As far as the grease Syl-Glide is silicone based and works very well. The Permatex Ceramic lube I use lists as being "Compatible with internal/external brake rubber and plastic hardware, including ethylene-propylene rubber."

Squealing has nothing to do with pad thickness. The only thing that matters is pad thickness - replace when they get under "nickle thin." You can addresss the squealing by applying anti-squeal paste to the backsides.

You talking about this stuff which I was told to put on the slide pins and "ears" of the brake pads? Or this other stuff which clearly advertises stopping squeaks but I've never used and really don't know where I'm supposed to apply it?

Also where am I supposed to apply it and what is the difference between them? Could I use both? Also can I use it on my motorcycle because the front brake squeaks constantly even tho the pads are fine?

I have always used the same stuff I use on the pins on the ears. I think you can put it on the back too, but I use this stuff: https://smile.amazon.com/CRC-05016-Disc-Brake-Quiet/dp/B000CINV88

I have no idea if that stuff works or not to tell you the truth, it's just what my dad always used and it doesn't seem to cause any problems. The $6 bottle will last me decades.

I use this applied to the back of the brake pads. I have never had a car make brake noise for a long long time with this stuff applied onto the back of the pads and calipers lubed up.
