Drilled/slotted front rotors

I just bought some Brembo drilled/slotted rotors for my gf's '99 ES (fronts only as she has drum rears). Was installing them today according to the markings on the box and I noted the slots were angled towards the front of the car. Every picture I have ever seen of slotted brake rotors, they were installed with the slots angled towards the rear. Either they are all wrong, or mine were mismarked. Anyone have any info on this? I searched for pictures on here hoping to see something, but no luck.

BTW, for anyone considering this I would preliminarily recommend it. I installed these rotors with Hawk HPS front pads and stainless lines all around, still bedding in the pads but the increase in stopping power is amazing.

yeah, I did a big group buy on these a long time ago. Everyone has been realpleased as far as I know. Mine have preformed flawlessly for over 20K miles.

the lines should point forward but either way wont be a problem.

If you go to their web site it tells you that the outer point of the slot should touch the pad FIRST. It acts as a slicing device to clean of the glaze on the pads. The holes are to let the gases off. So yes you put them on right. I went threw the same thing when I put mine on. Here is a picture of mine, and one of the car just because! I've had them on for a while now and love them. And I'll tell you they stop on a dime now. And I haven't noticed any pad wear.

Thanks for the input guys. I did some further bedding of the pads, the thing stops so fast now your nose will bleed. Hopefully my gf will get acclimated so she won't collect any trunk ornaments. I have been planning on redoing her brakes for a few months, decided to use her car as a guinea pig for the Brembos. Now I will have to get some for mine, at least the fronts anyhow. Not sure with the light rear weight of a FWD car that drilled/slotted are needed in the rear. Now I just have to worry about all the ricers wanting to race her when they see the brakes!

if you have a 4 lug car you don't need 2 rears..... the 4 lug cars are only front disk/rear drum.

Oh trinidad pros got alittle better rear brakes then.
Maybe we can source some parts then alot of guys want rear discs.

You should measure out the size of the front and rear rotors. Maybe they match up with the lx/dx front sizes and/or the es fronts.

Well this is only because some cars are used cars from Japan. That's what I have. There is NO WAY that trinidad could EVER have better cars than the US. Our cars suck. For instance, our mazda3 does not come 2.0 or 2.3, it comes in a friggin' 1.6!!! And it's so pricey compared to what you guys get for one there. Anyways, how would I go about measuring those things?


BTW, my FAMILIA is a 4WD. HEH HEH HEH!!!

Try a ruler for starters the lx/dx fronts here are 9.3" while the es is 10.2".

If the sizes match up the rotors should fit right on.

I don't know how I'm gonna use a ruler to measure the rotor and I am never able to crack those bolts to get the tire off. I'll try something though.

Just another note on rotors - the direction of the slot shouldn't matter, either direction is a 'slicing' action across the pad to keep clean. What you have to look at is the cooling veins in the middle of the rotor, those need to be oriented so the center of the rotor crosses the pad first - to allow for proper air flow. If the center veins are straight, it doesn't matter which way they go on.
I got drilled / slotted rotors from Brake motive (cheap ebay deal) and notice that there is a noise of the holes or slots passing the brake pad as a sort of faint cricket noise. Under hard braking there's some quick pulsasion as well, I think it's from the pad not being sized to match the slots - causing some difference in pad contact area as the rotor turns. Something else to think about when getting rotors upgraded. In any case they do seem to need less pedal pressure to stop, I assume from gas being releasing from under the pads.
