Brake disk question

Replace them before you destroy the calipers and have to replace those, too. Or worse, have one blow out on you on the road. How often you have to replace them depends on how you drive and how much stopping you do.

If the disks are really below minimum thickness then you should replace them. But it's worth measuring them yourself to make sure.

If you don't replace them, while it's unlikely that anything catastrophic will happen, they could develop cracks and eventually fail.

As for whether they should need replacing, it depends on several factors, including the type of pads you use and how you drive.

Thanks for the input. And LauraK too.

Unless you are doing the work yourself, it is not cost effective to replace the pads and then replace the disk later. When you replace the disk alone, you are also paying for the labor to replace the pads. I have even heard that you must replace the pads when you replace the disk. It is more cost effective to do all the work at once, rather than several jobs, since you have pay for the labor to remove the same pieces each time.

Thanks.

Modern discs are made of softer iron than previous as the pads are harder due to the lack of Asbestos. Pads harder so discs must be softer to get the same braking performance.

Your brakes are the only thing that stop over a tonne of metal that contains YOU and moves at considerable speed. Do you really want to take chances with them for the sake of a few quid?

Mind-you, at 200mm, surely they're still thick enough to stop a fleet of speeding battleships ;o)

diam maybe.

For most of us here in Australia, $700 is not 'a few quid'! 8-) That's a whole week's after-tax pay for anyone on an average income.

Erm... Shirley it's only going to make $700 worth of difference if the OP stretches the worn disks out to *double* their design life!

If "a while longer" means a couple of months then he really is only going to be saving a few quid.

Where in Australia are you. And which dealer do you go to.

Sorry for the delay. Eastern suburbs of Sydney, Pate & Vernooy.
