Ceramic brakes!

[Typ Vier]

PORSCHE says no, it is not possible nor allowed to machine them, once worn or damaged they need to be replaced no if or but.
They have a life expectancy of 300000km on road vehicles and are usually not used on race cars as they chip easily when not careful during wheel changes. All GT3 cup cars in NZ have the steel discs fitted.
If you use a diamond grinding tool similar to the flywheel grinding as mentioned earlier it may work but chances are that they will shatter.
Just checked, new ones for the front are around NZ$11000+ GST and for the rear around NZ$9000 + GST, these prices are retail. Pads for the front are NZ$ 1500. Alternatively you can use steel discs on the front with the 6 piston calipers but for the rear you need the calipers too as the ceramic ones are different

The pictures shown of those discs. They are shot. UNusable and NOT machineable.

Well, people have told me before some things could not be done (using 964 cylinders on a type 4 for instance), but I am a stubborn sob....

Today I wanted to show you it IS possible to machine them and I HAVE done it!





They look fiber-ish, but are very smooth, I assure you Its just difficult to capture with a flash light.

Still not proof they will work on the car, but one thing at the time

Good for you Wally !

Strong will and determination do go along way (911 shrouds don't cool )

Let us know how those brakes work out so we can envy you even more.

Good job.

Nice job, the fact is anything is possible if you really want to do it!
