Yeah here comes the mystery.  If the car has been driving for awhile, brakes moderately used- I get a weird metallic chatter/rattle noise right add the car comes to a stop.

Pads are good.
Rotors look good.
It's only at the very end when the vehicle is finally stopping.

It's a 2013 crv w/abs.  There's a very mild vibration matching the rattle noise.

Could it be they are just hot and make the noise?  Grease required anywhere?  I will try to get a recording tomorrow.

Pull the calipers back off OP, and replace the anti rattle clips that go between the pads and the bracket..they are either heat soaked and weakened, or out right missing...

Does you car have anti-rattle clips?  If so - check them.



Could also be dust shields rattling.



As with anything odd related to brakes - pull the wheel and take a look at pad thickness, rotor wear, the line and everything in the area.

The rotors may be warped and the pads scooting back and forth can cause the noise you described. If you can, take out the brake pads, and apply a coating of a high-quality ceramic brake parts lubricant to the points where the pads contact the hardware clips. If the noise goes away it's a good bet that the rotors need machining, or replacing if they're too thin to machine.  An on-car lathe is preferable if the shop has one.

My thought past the already mentioned is- Your might caliper might be seized or on its way. Best way to prevent is to clean and grease the pistons every brake job. Its pretty easy.
Link Posted: 8/30/2015 11:34:08 PM EDT
Ceramic pad grease usually comes with the pads, use it.
You dont notice the noise at higher speed because of wheel rpm's, road noise, wind etc.

Does the vehicle pull one way or another when braking fairly hard?

When the brakes squeal, it means they're working.

Meh, I have lifetime warranty on my calipers from oriellys. I'll just get new ones.

Mine squeak after some aggressive braking.

Mine are a little shaky, but it looks like I have plenty of life left on the rotor.

I guess if you have replaced all 4 already sure. I would rather not have to replace oem for a reman part on something i can prevent in the first place.

Holy crap. It took me a second for that to register in my brain. EXTREME seized caliper. How much noise was this making? It must have been horrendous. People are idiots.

I work at a brake shop. We see this more often than you'd think. We've even seen the remains of the disc break off the center hub. Scary to think we drive on the same roads as these idiots.

So if greasing the edges of the pads makes it go away, then the rotors are bad?

Maybe but true.

Physics be a bitch.... Motion gets transfered to heat, vibration and noise. Trick is to make all three low enough not to bother anything.

If the rotors are warped then you'll get some steering wheel shake when braking at highway speed.  The brakes will also have a pulsating feeling as you slow down and the pads are going across the high spots in the rotor.

FPNI.   Check to make sure the all the anti-rattle clips or shims are in place around the pad and not missing or broken.  They keep the pads snug in the caliper to they don't rattle around and make noise.

But if it's when the car is almost stopped completely, and the brakes are firmly applied, that means the rotors are warped/uneven and that's why they still rattle even when fully compressed?

Thanks for all the help guys.

Yes because the grease will temporarily stop the noise coming from edges of the pads rubbing back and forth.

Rotor/brake pad kits are not expensive on line.  If you can change a tire, you can do it yourself with the help of Youtube.

OP, You should be able to isolate the noise to a single wheel. Take the brake rotors off and look at the back side of the rotor.



If you have a seized floating caliper, only the inside pad is doing any braking. It is quite possible you have no actual pad left on the inside pad, and the metal backing plate from the pad is grinding against the rotor. This has happened to me twice on two vehicles. In both instances, someone else changed the pads, and didn't clean and grease the floating pins.
Link Posted: 9/1/2015 1:18:24 AM EDT
OP find yourself a balloon,blow it up. Now rub your finger on it until it makes a noise, that noise is a vibration It is one of the side effects of the coefficient of friction in relation to the speed,pressure and temperature of the friction surfaces rubbing together.
That's what your pads and rotors are doing and the vibration is transmitting itself through the rotor,hub,steering knuckle and strut and making the springs and your whole suspension vibrate But sure,grease your pads that will help

I am sure engineers have tried that as well as stainless steel shims on the abutments and rubber bushings on guide pins and magical unicorn dust in the brake pads trying to stop brake noise on disc brakes since they were invented......
