Front Brake Rattle - ARGGGGHHHH!!!
First off - it's great to be back around again. Life has been pretty busy, and I have had very little time to snoop around. But finally I am driven back by necessity - a good thing (I guess).
Problem - Loose (rattling) inner brake pad on the driver's side front wheel. Last year I did a fairly complete front brake job replacing everything except the rotors - they still were fine at that time. Recently, a squeak along with a rattle developed on the left side. I checked it and found the brake pads to be loose and badly unevenly worn from front to back. The rotor seemed slightly warped, so I have now replaced the rotors as well as installed new pads. Inner pad is still loose and rattle is still there. The inner pad is riding flush with the rotor (no visible gap), but I can push on the pad "tabs" down and it slides back and forth along the face of the rotor - causing the "tabs" to rattle against the caliper body. So what is going on here? Is the caliper loosening off too much or applying uneven pressure? The retainer clip (inside the caliper piston, holding the inner pad) was not replaced. Could this clip be too loose? Am I missing some hardware? Below are a couple of photos showing the installation and the area where I can move the pad. Any help would be appreciated. BTW - it's great to be "home". ![]() |

Re: Front Brake Rattle - ARGGGGHHHH!!!
It looks like that you haven't seated the pads yet. Have you drove it and stomped on the the pedal a few times? Can you hear it rattle when you apply the brakes or something?

Re: Front Brake Rattle - ARGGGGHHHH!!!
What do you mean by rattling? Is it like a vibration or squeeling or just plain sound like they're loose?
I agree with the break in but I wouldn't necessarily stomp on them. From the pics, it looks like your rotors are still fairly new. You can still see the polishing marks. This could cause a vibration on the brakes for some time until they're completely broken in. If they're just loose in there, it could be you are missing some springs that hold them in place. |

Re: Front Brake Rattle - ARGGGGHHHH!!!
this might be a dumb question but are you sure they are the right pads? how does the bolts/bolt holes on the spindle itslef look? the rotors straight possibly warped off center??

Re: Front Brake Rattle - ARGGGGHHHH!!!
I'd check the spring clip inside the piston that holds the pad against it.

Re: Front Brake Rattle - ARGGGGHHHH!!!
I think mine does this too, on the drivers side. When I hit ruts, small bumps in the road I get rattling.
When the brakes are applied it goes away so it's time to pull the wheels. Good luck to you finding the solution ![]()

Re: Front Brake Rattle - ARGGGGHHHH!!!
Do you have the brake pad clip on the inside pad?
![]() This should be clipped to the inner pad and then this clip (with pad attached) should fit tightly within the piston on the caliper. This keeps the pad from rattling around. These spring clips do wear out and loose they "springiness" so you might need to replace them. Good luck.

Re: Front Brake Rattle - ARGGGGHHHH!!!
Are there not two sizes of rotor, the hd and the standard. Isn't the HD rotor 1 1/4. Could he have pads for one and a different rotor???

Hopefully the new pad retainer clips will do the trick... |

Re: Front Brake Rattle - ARGGGGHHHH!!!
If the retainer clips are not really rusty, maybe you can bend them out just a bit.
I've never used it, but sometimes when you get new front pads they put some blue goop in a tube. Poke the tube, spread on the back of the pad, makes kinda like a gasket/noise supression type of thing. HTH....good luck.....don t. ..... |

Re: Front Brake Rattle - ARGGGGHHHH!!!
Yeah, i guess I could try the "bending" thing, but for less than $3 ea. I think I'll just replace them.
As for the "goop-in-a-tube", I tend to use brake caliper lubricant on the moving parts (bushings, bolts, etc.) but that's about it. I just hope the new retainer clips will do the deed - I'm feeling confident. |

Re: Front Brake Rattle - ARGGGGHHHH!!!
uneven brake pad wear... the first thing that jumps to mind is a frozen caliper pin. check that your caliper pins are both well lubed (copper or silver anti-seeze)

Re: Front Brake Rattle - ARGGGGHHHH!!!
This can happen too but don't use anti-seeze as I have seen it cause a reaction with the rubber o-ring and cause them to swell. They make disc brake pin lube specifically for this use. It doesn't have the possible reaction with the o-rings.

Re: Front Brake Rattle - ARGGGGHHHH!!!
If by caliper "pins" you are referring to the 2 long allen-head bolts that hold the callpers in place, yes I lubed these up. I used the purpose made brake lube that comes in a tube. I don't think these are binding.

Re: Front Brake Rattle - ARGGGGHHHH!!!
The Goop mentioned above is anti-rattle compound.It doesn't seem like it would make much difference but it does.I would get some of it and use it when replacing the retainer springs.
