It has come to my attention that I might have intalled my rotors the wrong way.



Is this the right way or not?????

 

From that pic I can't tell if it is the front left or rear right.
If it is the front left, then it is correct. If that is the rear right, then it is incorrect.

 

You know, I noticed that in the pics in this thread.

You'd think Nissan would know how to install slotted rotors.

 

Driver side......

 

thats how i have mind installed, looks right to me.

 

here is another thread about it.

i think i may have mind installed wrong, i cant really remember right now, haha.

according to this you have them the wrong way...... on my 02 max I installed them the way the site has them......... my 02

 

The direction of the slots on the outer surfaces is not important. It's the direction of the cooling vanes inside the rotor that matters.

 

The information I have recieved from a friend at Skip Barber and was confirmed by an SCCA friend is the rotor can be installed either way. The way you have yours installed is the way mine were done as well. This postion is the quietest. It is best for street use. When you flip the rotation to a saw blade configuration, the braking is more aggressive. It also creates more heat and wears pads quicker. Last but not least is creats a bit more noise. I am sure all of you with slotted rotors have felt the slightest vibration in the pedal post installation. It was brought to my attention while watching the 24hrs at Daytona. Look at the brakes on those cars. Most use slotted and crossdrilled. They are almost always installed in the saw blade configuration. Thier intent is to provide maximum braking force during the race. Both rotors and pads are easily replaced and they have a ton of backups. This is why I chose installing my pads the way you did. Not only will the pads last longer, it provides great cooling and less noise. This is just my understanding based upon conversations with race and SCCA friends. I have not installed them the other way and do experimenting with braking efficiency of braking distance. If I had the money, or someone else who wanteds to try it, I would gladly experiment and provide data proving or disproving my information.

 

PowerSlot rotors are labeled...but yes, that is correct for PowerSlot.

Some rotors it does NOT matter since they have non directional vents/veins.

 

All mine are swept forward, but yes, it can be done either way...

 

When things, like PowerSlot rotors say left or right.

Is it from inside the car or standing in front of it?

 

L means the left side of the car or driver's side. R means...

 

Same as aircraft. Always as if you are sitting in the pilot's (driver's) seat.

 

This is the most important post in this thread and seems to have been missed by most readers. If the vanes are spinning in the wrong direction, the "impeller" will be pumping air the wrong way.

 

Can you explain in detail what you mean? I have my rotors the correct way, but why does it matter what direction the rotors face? If the main reason for slotted rotors is to vent the gasses that are between the pad and the rotor surface, I would assume they would work either way.

 

The pinkish dashed lines represent the vanes inside the rotor which are in fact an impeller. As the rotor turns, the vanes act as a fan pumping air outwards. If the vanes were to rotate in the opposite direction, they would pump no air as the centrifugal forces are acting in opposite direction of a very inefficient impeller. End result, no cooling, brake fade, rotor failure.

The slots are there not to cool the rotors, but to "cut" the pads and keep them wearing evenly.

 

Gotcha. So the viens on the interior of the rotor help dissipate heat. However, the slotted part of the rotor also helps dissipate the gas build-up between the pads and the rotors. This was my original question, does it matter which direction the "slotted" rotor faces or rotates? I would now assume that the direction of the slotted rotor should be the same as the interior viens to properply dissipate the gas build-up.

 

I have answered this question to Lontar1 directly. But i just called up to the place i bought my cross drilled brembo (originally drilled by Brembo). They customer rep told me that the direction should be on the opposite direction as the picture above for sure. The end of the drill (near the side) should be grabbed by the brake pad first.

Since 2 word is better than one. I called Brembo directly for the second time asking the same question. THen the answer is the same. He also mention that sloted and drilled have the same direction.

About 3 hours ago i stopped by to the corvet dealer, and see the direction they have. they have the brand new model one which has cross drilled rotor. And it is the same like what i instaled. Which is the same like what the brembo customer rep, and shop rep that i have asked.

But may be different brand has different direction to get it installed.

O yah one more, i see overhaulin. They installed the rotor in the same direction like mine.

Enough, may be my opinion get you borred already I am afraid that people will get mad at me

 

The rotors are marked as to where they go.....
