--> QUOTE(joe b @ Jan 31 2007, 08:40 PM) ←I've just learned that the insert's are steel and i am running steel brake bolts. Could that be the reason the helicoil threaded, 'caus they're normally quite strong aren't they?So, if i do what your saying, i would have a new large hole would that mean i would put a normal insert in and have a bigger threaded bolt or a bigger insert and a normal threaded bolt? Any more views/thoughts/experiences? Cheers, Joe. steel threads are much stronger than the normal ones you get in a frame because aluminium is soft. so steel should be stronger if done properly
