Powerslot Rotors

[Spoolin98]

I did some searching and couldnt find my answer to these questions. I upgraded to awd calipers with powerslots and hawk pads.

1. Which way do the slots in the rotors go when putting on the rotors? I checked there website and it doesnt tell you anything. Neither does the paperwork that came with the rotors.

2. The rotors and hawk hps pads both came with instructions.

With the rotors it says to not brake aggressivily for 10-20 miles before starting the break in procedure. The pads tell me a series of things to do to burnish the pads. Is it ok to drive on the pads for 10-20 miles with slight braking before breaking them in? Im assukming so, but just checking.

I run the PowerSlot Plus/EBC Greens on my 2G...

On mine, the slots (starting at the top from the center) curves back toward the rear. Mine were labeled on the box (L/R). I drove with easy braking for ~10 miles to my favorite "break-in" spot.

I also have the PowerSlot rotors and mine were labeled L and R. It should be stamped on the part that goes over the hub. I have Axxis MetalMaster pads, but followed the break-in instructions for the rotors over the pads. I figure it'd be cheaper to replace messed up pads than rotors.

Thanks for the help guys, much appreciated...

Interesting question. I'd always thought the "correct" way was so that they'd be "sweeping" outward, with the leading edge of the slot pointing in the direction of rotation. Then (somewhere in my Bookmarks that the new version of FireFox seems to have screwed up) I found a Brembo site where they say to install them backward from that. Maybe it doesn't matter, but Formontoya's way is what I thought was "right".

Pad "bedding" is another area you'll get thirty stories about the "right" way. Odd the rotors would include break-in procedures.
You'll be fine using them lightly before "burning in".

It does make a difference as to which way to face them. The "vents" on the fronts have to be facing the correct direction for proper airflow, the "solid" rears might not be so critical (but for some reason they are).

As well, a set of Baer brakes...the slot pattern faces forward, in stead of to the rear as mine do.


edit:
I can't remember, but IIRC the PowerSlot Plus rotors have front vents that are straight out and conceivably would not make a difference. However, they do have left and right versions. I know for sure that the Baer rotors have directional vents as the drill pattern needs to fall within the vent "hole". And the Baer setup vent "scoops" the air as opposed to "venting" the air from the center of the rotor.

hey bud, the powerslots are boxed with labels. Check the part number label. One part number ends in L the other in R. Let me know if you have any other questions.

Thanks for the help. The paper with the rotors says that the cadmium plating needs to be worn off before doing any aggressive braking.

I noticed that later,
But I tend to over analyze things, so I started wondering if it meant left and right from the drivers seat or left and right from looking straight on at the car. The obvious answer would be from the drivers seat, but like I said, I over analyze everything...
Thanks for the help

It seems the slot direction varies from manufacturer to manufacturer & I honestly don't think it makes much difference either way. Whats more important, is that if the rotor is directionally vented internally, its installed in the correct direct, to achieve proper cooling.

Looks like the OP answered his own question but yes my rear powerslot rotors were marked left & right. Left is normally the drivers side & my rears are installed with the slots facing rearward.

As for rotors & not heat cycling them to bed in the pads right away, I haven't heard of this & have never done it. I always bed my pads in basically right away, once I have verified proper brake operation & am able to drive to an area where you can do a proper bed in procedure.

It's been stated early, but I just thought I'd add a picture.

IF the vanes are directional, it matters which way the rotor rotates.

You must be logged in to view this image or video.

The vanes should never be "scooping" the air, because that doesn't work. It works as a centrifugal pump and pushes the air from the center out. If the vanes aren't directional, it doesn't matter which way it rotates.


The slots don't actually make a difference either way.

follow the brake pad break-in procedure.


Hmmm Hawk HP Plus are about the same price as a set of rotors

I can see them wanting you to wear the cadmium plating off before bedding. Cad fumes are highly toxic.
