Rattling disc pads - grrrr
My Wilwood Dynalites are rattling at low speeds (under 50mph) and they are so loud it is embarrassing! The pads seem very loose in their calipers.
Rally Design say that Dynalites do not use anti squeal shims so how can I shut them up?
Cheers,
Raz

Ant-squeal shims won't do any good for rattling, coppaslip might do it, but anti-rattle springs/clips are really required.
Might also be an idea to check the discs for run-out.

hicost - residual pressure valve seem a bit too hicost  but I will bear them in mind.
I found some anti squeal pads in my local autospares shop but I dont think they will stop them rattling. Copper grease is worth a try I suppose but I
have my doubts.
I was thinking that maybe a little spring installed over the central split pin might just exert enough pressure to stop them rattling - a locost
approach 
What do you think?

THis is exactly the same problem as happens with alot of race pads, we had a conversation with a guys at Autosport about this very problem. The
reason they rattle is because with race pads they have more tolerance built in to ensure that during racing they do not stick.
You may find that different pad manufacturers are better but really just trial and error, other thing is to make something yourself but key thing is
obviously to make sure they don't stick!!!

What you're proposing is very similar to what Girling did on the original M16 calipers.
Those pads are retained by two pins but otherwise a very similar concept. It should work very well if you can find a suitable spring.
If not you can buy piano wire (spring steel wire) in different diameters from most aircraft model shops and you could make your own.

welcome to wilwood brakes!!!
lol
If you want quiet (some might say "proper" brakes then you need to speak to AP, and pay the money, otherwise live with it!
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

We had the same problem with an off road car we built using Wilwood brakes, We installed the Residual pressure valves in and they cured the rattling,
but there was a huge increase in Brake dust on the wheels.

It has been suggested that Biro springs might do the trick - ultimate locost solution?

Holding the pads back against the pistons would cure it and something like Biro springs between the pads would be easiest and cheap.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
