Hello to all on the S2 Forum,
I'm having a very (seriously) heated discussion with a friend regarding the correct rotation of slotted/grooved brake disks and I've entered into a bet on it so please help me!
I believe that the slot/groove on a brake disk should start from the inside of the disk and work outwards, past the outer edge of the disk. This helps wiping the disk of particulates and hot gasses whilst under hard braking and uses centrifugal action to assist. As far as I'm concerned its the same when assembling the plates in an LSD: If you put them on backwards they can't wipe the oil free off the plates, and it won't work as well.
This is doing my nut in, and after helping my friend fit some tasty A.P. disks and calipers to his rally car it has almost come to blows, as I disagree with A.P's instructions.
Please help me S2 Forum, you're my only help....
