Interesting article written by someone who did not understand engine braking comes before braking downhill and creating the fade scenario in the first place.
There are one or two points I would address, cross drilling does reduce mass but also helps prevent distortion IMO by relieving internal stress in the disc material during severe heating/cooling events. He mentions the cross drilled holes get blocked, that is true, my competition Discovery had the cross drilled discs front and rear, mud and all sorts jammed them up, and the screeching noises as little stones get caught in all sorts of places would drive you nuts for days after being off road.
The point made about have 6 or 8 pot calipers added to the pressure on the disc creating more heat is at best a weak one, remember the bigger pad will absorb more heat and will disperse it through more pistons, more volume of fluid and of course the bigger calliper.
He questions the claim that a certain brake is lighter so cannot be better, this is about application, a lighter disc offers the suspension less unsprung weight so is in fact an advantage in certain vehicles.
I went with dimpled and slotted front and rear on the 80, I can still overheat them when driving enthusiastly, but there is no hint of distortion or vibration, pedal stays firm but you can feel there is less retardation for the same pedal pressure once they get hot. And of course no mud or stones in the non existent holes.
Some of the claims in his advert example could actually be valid for example, 30% better stopping power, you can modify stopping power by modifying the pad material, or put another way, greater retardation for the same pedal pressure for example. But it is true many are easily misled by the skills of a good marketing department.
IMO the stock 80 brakes are just about adequate, when loaded to max they are not really up to snuff. Do my brake mods give me better brakes? Without doubt there is more initial bite and and the pedal has a better 'feel', all subjective I know but it is there, I would say in overall performance probably yes, but cost ratio versus stock, then no.
Right, now where was that advert for the penis enlargement device?
