Disc brake replacement

[ranton-inc]

Just a thought 'though, why is it bad for discs to get thinner? is it a heat issue or can ventilated discs could get weak if too thin?

i think its to do with casting surface tensions and heat dissipation ie they are more suseptible to warping etc...

Ahhh...Cheers for all the replies. I guess I was just a bit paranoid (to use a better word) that I was being taken for a ride.

On another note, I found out after my tune last week a few interesting things about my car.

60k and apparently the car was still on the original coolant, and a few other things. All I know is that is running a whole lot better after the service.

Red coolant lasts up to 250 000kms i think the figure is from top of head.

Think of the disc rotor as being a heat sink.

• Less mass means less ability to absorb or dissipate heat.
• Less structural integrity & increased heat increases likelihood of warping.
• They can get thin enough that the brake pad can fall out of the guide slots in the caliper.
• They can get thin enough that the piston will pop out of the caliper
• More heat means increased likelihood of hotspots, cracks and ultimately, structural failure.

Bendix is the only non-OEM brand that doesn't void manufacturer warranty.

That is definitely NOT true! Why is Bendix any different to any other aftermarket manufacturer? In fact, the exact ACCC ruling is:

"If a part is non-genuine, but is interchangeable with the genuine parts, it could be seen as being fit or appropriate for the purpose and would therefore not void the manufacturer's warranty."

How is that a Bendix only thing? Bendix pads would definitely be in the lower range of quality and performance vs. dollars...
