i had the closetest mech installed these for me since i broke my drill bit in the two screws that you need to take out in order to take off the rotors.. but i haven't really had a chance to look at these until tonight when i was just bored and noticed this.. i installed these sunday( day before memorial day)... is this right?


left side






right side...



should it be like this? it's rotora slotted w/ raybestoes ceramic quiet stop.( i coudn't wait for EBC to ship) . it looks as though it (the caliper) isn't all the way in or something.. can someone show me a pic of rotora slotted for reference...? should the entire rotor be used????



btw, i drove about 100 miles on these and so far, no brake dust at all. .. but i am still in the break in period.. so that might change.. i dont know if it's my mind, but it seems like i've lost braking power ( aka.. the bite)... wonder if it' will change once i break it in.. or does the pad just suck??

 

FYI i know they are on backwards, i didn't want the rotors to eat up my pads..

 

So why go with slotted rotors if you're not going to use them properly?

 

I agree.. why even bother..Your rotors wont cool properly. The pads are grabbed and the slots so will eat it up either way.

 

well, being that they are slotted will still be better than blanks.. and they are more of cosmetics purposes than performance b/c i dont really drive hard. (so they are there just in case i do..)


back to the prob.. should all of the rotor be used??? it doesn't look like the pad is all the way in grabbing all the rotor..

??

 

egh..... do yourself a favor, put the rotors on the right way; the way u have it now u r better off with stock.

 

c'mon guys what's the flaming for? putting the rotors facing / or \ is the driver's decision. it isn't NECESSARY that i have to have it that way. if i need the stopping power the slots bring me i'll put it the recommended way.. it's a fact that this doesn't hurt the car or rotor for that matter, in any way. it's just a drivers choice of braking power is important or if pad life is more importantbut either way, the stopping power is greater than w/ blanks. ... it's a situation of advantage/disadvantages... you guys act like this is the first time you've saw someone put rotora this way.. there's more than a few threads on which way the slots should be facing. ... it's not like i'm modifying a "mod" rendering it useless..

seems like i'm getting the same reaction as if i'm putting on the sarona kit on my TL..


but c'mon, back to the issue.. which is, should my pad be eating/grabbing only 90% of the rotor? is it always like this/ is this normal? cause i've never noticed it w/ OEM.

slotted rotors 'are designed to heat up your pads quickly for optimum breaking performance, without removing surface area for the pads to contact. In the slotted rotors, slots wipe the surface of the rotor forcing the gases to expel through the slots. The slots also greatly improve wet weather braking by preventing hydroplaning between the pad and rotor. The slots are angled to use the rotors’ direction of rotation to enhance their performance, which makes the rotors side-specific with left and right side rotors.'

There is a reason we are picking on you forget the pad life, you paid for better braking power, so why not use it? and dont u dare get the Sarona kit lol

lata

 

lol. i wont. i might change these sometime this week then since i do feel like the braking power seems worse than w/ the OEM. but i'm still thinking it's b/c the pad isn't grabbing all of the rotors...(like the pics shows) w/ the fact that i'm still in the break in period.... i'm just going to have to take the wheel off and see for myself in the morning..

will post an update.

 

1. This has been said, but I will say it again. Those rotors are marked for left and right side applications for a reason. If you think you know more about these rotors than Rotora itself, then by all means, keep them backwards. Your reasoning for installing them backward to save pads has no ground, because those slots will eat up the pads either way. They are designed to expel gases more efficiently, and clean up the pads' surface to prevent glazing.

2. Check by the inner edge of the pad and see if it lines up with the edge of the rotor where the hub ends. In other words, does the pad extend and line up with the boundary of the rotor and hub? If not, then you're okay. Those pads just aren't big enough to make full contact on the rotors. But if they do line up, then there could be a problem.

Did you check your pads when you got them in? Were there nipples/tabs on the back of them? If there were, then chances are they are making contact with the caliper cylinder. This is what happened with my Hawk HP Plus pads, and due to the nipple/tab hitting the caliper cylinder, it was being applied to the rotor at an angle, only on the outer edge of the rotor.

Or it could simply be that they are still being bedded in, and the anti-rust coating hasn't worn off completely on the inner edge of the rotor. To be on the safe side, take off the calipers and inspect the pads and the cylinders. If there is no problem and you're sure that the pads are being applied to the rotor at the proper angle for full contact, then no worries; they are still bedding.

Good luck.

P.S. How many miles since installation?

 

kinda lost me on this step..

i remmber checking out the pads... but i don't recall seeing or noticing nipples or anything on them..


but yeah, i plan on switching the rotors the other way. and it's been around 100 miles since installation.

 

Ok, let me try again.

In the following picture...





Where is the end of the pad? Is it at the line where the gold-colored area is? Or does the pad extend all the way to the edge of the rotor, toward the hub (hub is the part with the holes for the wheel studs)?

If the pad extends all the way to the edge of the rotor, then the pad isn't making full contact with the rotor, probably.

I hope that made more sense.

 

I suggest you do a bit of research. In addition to the slots being directional, you also need to take into account the vent vanes. These are designed to channel air in and thru the discs. Mounting them incorrectly will drastically affect the cooling of the rotors.
Just thought you should know.
