just got my grubby mits on a set of Brembo grooved and dimpled front disks.

Anyone know which way round they go.

Sounds like another of my dumb questions but this is what i mean:

BACK--->FRONT

or

FRONT--->BACK

 

Help

top one :)

 

as the picsture shows them they roll clockwise :)

 

HTH

.... so drawing air down the grooves towards the hub then....

 

Thanks :)

Top way will eat pads more than the bottom way.

I always assumed that you drew air away from the hub, and also agree with rodders. but it looks like its a bit of a grey area? my rears are on the top way but have drilled going on the front when they arrive.

Does it matter??! :wack:

I asked this a couple of months ago too.

Looky

 

The concensus then from people who had bought discs that were handed and had the fitting marks was:

 

 

 

 

 

 

 

 

 

B.

The bottom one.

Top way will eat pads more than the bottom way.

but the fact there eating means there grabbing means there stopping :)

As well as increasing the cooling area, water is forced into the channel and expelled without interfering with the braking surface between the disk and pad.

 

It has to be the bottom one.

top one deff

but the fact there eating means there grabbing means there stopping :)

 

And cost more, specially with that amount of grooves!!

;) Bottom one, or are my eyes playing tricks on me? ;) ;) ;) ;) ;) ;)
