Rattling Calipers
« on: October 03, 2010 - 08:19:44 AM »
After 5 yrs resto time I've finally got my 70 Challenger back on the road. :woohoo:
Just.
But it's nothing short of stunning and is knocking everyone's socks off.Including mates who run professional resto shops :thumbsup:
Time has been short this year due to a heavy workload but that pays for the toys,doesn't it? :grinyes:
Still a few things to sort out (including some parts I still need to get from Slotts)and a few other gremlins which have become apparent with the few cruises it's had.
Which brings me to the reason for this thread.
When I travel over bumps there is a really bad clunk clunk rattle rattle from the RHS front.
Everything is tight under there and all front end components are new but I noticed the floating half of the caliper is loose in it's grooves and rattles.
I'm 95% certain this is the problem as I can prevent the clunks and rattles over bumps by riding the brakes which is obviously applying pressure to the calipers preventing them from floating.
Is there a shim package or something to prevent this problem or do i need new calipers?
I ask on here as the US calipers are assembled somewhat differently to our Aussie ones so I figured you blokes would be the gurus :2thumbs:

I assume you have slider not pin type calipers , the repro hold down plates seem top be deficient in strength to hold the calipers tight from some suppliers

Not sure if this is the right setup, but I managed to get the older style anti rattle clips for mine, they came with the metal rod type. Rich.

, the hold down plates on the slider type are cheaply made by some suppliers , swap them for a stronger set

RustyCuda - nah mate,mine's different to that.I think they're the same as what's on my 69 barracuda.I had to make my own ones of those U shaped clips as some of them were broken.

Anyway,I've sorted it.
I pulled off the two slider plates off the offending side and one of them seemed to have been installed a bit skewed.
Put them back on properly and all seems good :thumbsup:

Many thanks to all those who replied :2thumbs:

Ken a mate had the same problem on his VK Valiant so he had the bracket brazed up to remove the excess movement on the non pressure side, I saw it before and it was new and Chrysler said it was normal, extremely annoying. The plates he had were tight being new.
