Grooved disk problem

Hi i have a problem. How can I set the grooved disk on the car?(I mean the direction) Do you have please fotos?

You can put them on either way. With the grooves facing down and forwards is probably more common, and makes a little less noise. According to some fit them the other way they will be more aggressive and louder.

I don't think it makes that much difference either way though

Yup, either way :

I have the same direction like you whatmoretyres. But the brakes are very loud.

I have 3G 10 Groove Discs all round

You can have the grooves facing in either direction, but there is a "gentle" orientation and an "agressive"

The best way is to have the disc so that the first section of groove to touch the pad is the bit nearest the centre of the disc - therefore, the last section of the groove in contact with the disc is at the outer edge

Graphically, if you're looking at the right hand front wheel, the grooves (at the top and bottom of the disc) should look like \ \ and not / /

That means the direction of Tartandude is correct?

Yes

Phew

It is still notably noisier braking with this setup compared with standard disc and pads, but then I would expect it to be. Im using Red Dot Fast Road Pads as well incase that makes a difference

Discs are handed by their internal veins, not any external grooves.

If the two halves of a disc are seperated by pegs then it doesn't matter, you can put them on whichever way you want.

If they are seperated by helical vanes then it is important to get them the correct way, the theory is this: The air is sucked in at the centre of the disc and thrown out of the perimeter, so you put them on accordingly.

They work thats all I know

My pagid discs are the opposite way to tartandudes but they came with stickers on them telling me what side to fit them ?

I guess it depends on the manufacturer.
