one quick question...do i have to bleed the brakes when i do the change?? i've been lookin' around online and some ppl say that you have to bleed them first then replace the parts, then some say to do it afterwards...but it it necissary to bleed them at all??

can't i just replace the pads and rotors??

Bill Hook

Not necessary to bleed the brakes, but it is advised. You can buy a bleed kit for not much money and get a friend to help push the pedal while you work the wrench to get fluid out on the downstroke and not get air bubbles on the return stroke.

Front brakes do 70-80% of the braking, research front brake upgrades before considering a back disc swap.

P.S. Those slotted rotors are on backwards.

if those rotors are on backwards then EBC labeled their boxes wrong because mine are pointing the same way...woudn't you want the slots giong in the direction that they are pointing because the way they are now it would allow any dust on anything to escape otwards where as if they were the other way it would for all dirt and grime and what not would be forced to the center of the rotor correct??

BrakeExpert

EBC may have reccomended them that way. From what I know about racing, the slots should be facing "forward" meaning the top of the slot contacts the pad first, opposite of what you have. Slots arent for dust. The benefit of having them your way is that they are quieter. Slots faced the correct way tend to make a lot of noise, and thats why a lot of car makers that use them (ok its only a few) will put them on wrong because the braking power is only reduced a short bit but their customers would rather not have noisy brakes. Most people cant tell vibration from a low brake pad squeal.

I've been looking around at a lot of other brake setups (usually M. Benz, or vettes) and their slot pattern is the same. But it makes sense the way you described it, and I don't really think I would need any more braking power (I'm not racing)

This is just something I found on the Brembo site as I was lookin' for information on direction, as you said sometimes it's different for racing / noise etc...thought it was interesting

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">Which direction should the discs rotate?

It is a popular misconception that the slots or drillings in a disc determine the direction of rotation. In truth, for an internally vented disc, the geometry of the vanes dictates the direction of rotation. There are three vane types in use:

Straight
Pillar vane (comprised of many small posts)
Curved vane

The first two vane types are non-directional, and can be used on either side of the vehicle. The curved vane disc, however, is directional. A curved vane disc must be installed with the vanes running back from the inside to outside diameters in the direction of rotation. Orienting the disc in the manner creates a centrifugal pump. The rotation of the disc causes air to be pumped from the center of the disc, through the vanes, and out through the outside diameter of the disc. This greatly enhances the disc's ability to dissipate heat.</TD></TR></TABLE>

I think the reason the EBC rotors are in the other direction is because they have "curved vanes"

sound right?

can anyone tell me if the rotors on the new civics are bolted on or if they just sit on the lugs?? trying to figure out whithout takin' my wheel off, if i'm gonna need an impact wrench to do this today or not...

I'll post up some pics when done. Thanks

Brembo is talking about vented rotors (like on the fronts of most cars) looks like a front and a back with webbing in between.. alot of rear brakes tend to be solid disc rotors with no place for air to cool the inside of the rotor.. Not really related at all to slotting or drilling.. just very basic cooling of the rotor
