front brake clunk

[slider]

I have a 97 standard and the front brakes sometimes make a clunk when  applied,it dosent happen all the time just on occasion   anyone have a solution to this?the pads have plenty of meat left on them so I dont believe that its the pads.It just dosent sound right coming from a valk!!

From everything I've read here, and from my experience with my '99 STD, it's normal. Has something to do with the fact that our Valks have floating calipers, or some such thing.

Yep, as the rotors get more use, they become loose on the hub. You can grab the rotor and rotate it back and forth a little each way.

That's the noise you hear.

Ricky step away from the drugs  he means the calipers not the rotor !!!!

Actually both contribute to the clunk that you hear. Floating rotors and calipers will do this new, and as they age or wear they clunk more. Check to make sure that nothing in the breaking system is actually loose (ie bolts) and then ride.

thanks for the input--being a owner I figured it was best to ask the pros if there was a need to be concerned-thanks to you all!

 Floating rotors ?????

Boy, that "corn-fuses" me. How does a rotor float ? 

[BonS]

A floating rotor is an assembly consisting of a hub and a rotor that are attached by a "loosely" fitted attachment that allows the rotor to move side to side and a bit forward and backward. Here's a close up of a randomly selected example. The rotor is in the lower portion of the picture and the hub is in the upper portion. The blue part is the attachment that I'm talking about.

Very nice explanation and the picture is worth 1,000 words. Thank you! 

I always wondered what those silver "disks" were on my hub/rotor. Now I know, though I have to wonder, why? If the calipers can float, what is the advantage of the rotor floating, too?

[roboto65]

The reason floating rotors are better is because of well heat it allow them to cool and not transfer heat to the hub plus it allows them to make a lighter rotor as you can see the inner is aluminum and the disk is steel..
