Front Brake Rattle - ARGGGGHHHH!!! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'd check the spring clip inside the piston that holds the pad against it.

Thanks for all the quick responses. Here's my answers to your questions...

I have driven it quite a ways, and hit the brakes pretty good. It brakes well and the right side is quiet. The rattle does go away once I press the pedal enough to start slowing, and since the pad is loose, I assume that's what it is.

It is a loose rattle every time I hit a small bump or crack in the road. The rattle was definitely worse when the old pads (which were looser) were still in service.

The rotors are brand new and they appear to run true. Like I said above it is definitely a rattle and not a vibration under braking.

I believe the only spring is the one inside the piston - which I assume may be too loose. The outer face of the pad has the shim rivetted on (as opposed to clipped).

I'm pretty sure the pads are right since the right side is operating perfectly. Everything else appears good too.

Yeah, maybe I should look at replacing these.

Thanks guys.

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
