    The presenters voice has the same effect on me as fingernails on blackboards.

    Sounds like a great idea, would be a boon to the transport industry preventing brake fade.

    Very interesting technology! I love the engineering thinking process behind it. That's what really high end manufacturers do well.
    I nearly p155ed myself laughing when I saw the replacement service price, US$11k..... for 4 rotors and 4 sets of pad plus bolts and clips..... plus labour....

    Way to expensive to be practical for the transport industry. This is really only going to be a thing track cars, and drongos with too much money that buy porsche's as daily drivers. also brake fade isn't a issue if you are driving your truck correctly.

    I realise that it's expensive now, but like a lot of things price will eventually come down to an affordable/viable level, and I know that trucks, IF driven correctly, don't have that problem, but like a lot of training that is done nowadays, it fails to pass on the correct information!!!
    I think, if a lot of us were to do our apprenticeships again, we would be astonished as to how little info is actually passed on, from back then to now.

    Hi Guys,

    Virtually all businesses are price gouging at the moment, desperately trying to recover from the weeks of not been able to trade. The supermarkets are worse of all ! We, my wife and I, have seen prices jump by 10% or more in a week on some items. Even the so called cut price stores have pushed prices up.

    The price of milk has gone up 10p for a four pint bottle since last week.

    There's some interesting developments in the transport world, part of a shift to what is generally termed 'services'.

    I'm told that rather than buy tyres now, you can effectively 'lease' at a certain rate per kilometre. That actually has a major impact on the whole chain. The end user gets a guaranteed price, and the manufacturer is now trying to build the best tyre he can, not the cheapest.
    Same could apply to brakes. If you were paying for kilometres, or brake-minutes, however measured, the manufacturers goal changes from 'cheapest' to 'best'.
    But certainly I'm not about to spring 11k on rotors - bad enough facing $300/tyre. 😢

    I couldn't agree more ! Have you noticed that more vehicles are being supplied with the more expensive high performance low profile tyres these days.

    Yeah...but have you noticed that more vehicles are putting down a lot more power these days as well.

    You don't have to replace them with the same thing when they wear out if you don't want to, but I don't see how stickier tyres is a bad thing.

    What would be interesting to test is whether some of the fancy coatings used on cutting tools to reduce wear would provide any meaningful benefit or if they'd rub off too quickly.

    Hi Elan, Guys,

    No I hadn't ! But at my age with a 1 ltr 3 cylinder engine, I would rather have economy rather than power. On average I get around 65/68 mpg. My camper van that has a 2.2 ltr diesel engine and is rated at 130 bhp only returns 30 mpg and costs me double the road tax and double the insurance, yet spends 70% of its time parked.

    You don't have to replace them with the same thing when they wear out if you don't want to, but I don't see how stickier tyres is a bad thing.
    I only discovered that the tyres were expensive low profile ones when I went to get a price for a replacement set. I'm looking at 550 for the four balanced and fitted. That was the best price that I could get without going for standard profile tyres.

    What would be interesting to test is whether some of the fancy coatings used on cutting tools to reduce wear would provide any meaningful benefit or if they'd rub off too quickly.
    I must admit that I've not taken much notice. The only coated cutting tools that I have had have been drills and I've ground the coating off those when I've four facet ground them. But it seems that the manufacturers like Dormer, Presto and Guhring seem to push them.

    I meant as a brake disc coating, they definitely work on cutting tools. You only grind the clearance face on drills, so you're still going to get some benefit from the coating on the cutting face even after sharpening.
