Brake pads

[scdmarx]

I replaced my rear pads yesterday with these pads I got from ebay. I had intended to ask here, but just didn't get to it. I have never heard of kevlar as brake friction material. I was wondering if there really is any advatage to it or is it mostly hype. These pads I got didn't really cost anymore than what I've been paying for the usual EBC brakes I've been getting in the past. I think it was $42 buy it now, and included 3 sets to do both fronts and the rear. But I only did the rear so far. Still have a little left on the fronts. Yesterday after installation and fluid flush, the first time the rear brakes were applied it was almost like nothing there. I figure this will require some break in. The second application was quite an improvement over the first. The third application I thought I was gonna go through the windshield! Smooth, quiet, awesome stopping power. I'm impressed! And I'm sold!
Just thought I would share. :thank_you:

Anyone else ever used kevlars and have anything to say about them?

Never used kevlar brake pads, but I know a yacht that used kevlar for sail material and boy were they in for a shock when they went to cut the sails! Every shear they used got torn up and would not cut the fabric! :smilie_happy:

Finally, they went to a high speed grinder (similar to a dremel but slightly larger) with diamond tipped blades and finally, they could cut the sails! Talk about bullet proof! :yahoo:

No direct experience with kevlar pads but from what I read they are the best to get for stopping power and longevity, used in racing and resistant to fading.
That's a great price you got for all 3 sets!
I didn't get them last time because they were so much more than standard pads, now I know to shop around more next time.

Here's a better deal than I got from the same seller. That is, if he will combine shipping.

Search through his ebay store to see if he still offers the set of 3. I paid $42 w/free shipping. My auction page states there were 10 available and as of this writting he has sold 6.

That's good to know.... thanks for the heads up, ill be sure to try those out next time I change my breaks :salute:

I bought a set of sintered brakes for my friend who rides a sport bike..

Drive safe!

I just ordered 3 sets for my wing 2days ago and awaiting some sun to install them.

these are the pads I ordered.

if they sqeek we'll be going back to organic pads.

pulled this off the EBC site

"There are three types of brake pad used on modern Motorcycles and these fall into these groups, Organic, semi metallic or sintered.

Quickly explained, semi metallic pads are blended with up to 30 or 50% cheap steel fibre, organic pads are made with man made fibres such as Kevlar or Twaron bonded together with a petrochemical resin and sintered metal pads are copper alloy fused together under heat and pressure."

Speaking of brake pads.....

The last 2 times on the rear only gave me 5,000 miles of service till they were down to metal. I just installed pads for the 3rd time on the rear. I use new fluid to flush out the old fluid every time I replace the pads. The rear tire rolls freely and I can feel no brake drag.

The fronts at this time still have a little use left at 10,000 miles. They were dragging shortly after I first got the bike, and I changed all the rubber parts to solve that problem.

Any thoughts, ideas, or BTDT's ? I can't see or feel anything wrong. Think maybe it's just time to kit the caliper? Or is it time to look into the crystal ball?

Look into the crystal ball for the answer and let me know. I have the same problem with short life on the rear.
To help them last longer I've been leading with the front brake then applying the rear only when needing to stop faster.
That seems to be helping but nowhere near the life I'm getting out of the fronts which have the same pads from when I bought it almost 30k miles ago.

I've rebuilt the rear caliper, front's haven't been touched. All new fluid and SS lines. Masters haven't been touched.
I have front caliper rebuild kits on the shelf but hate to ruin a good thing.

The harder compound pads need heat to be effective, so your first few stops will prolly be "mushy". One problem with the harder compounds is accelerated wear on the rotors. Sure, the pads will last longer, and stop you better, but it comes at a cost to the rotors. Kevlar/carbon fiber type pads really need cryogenicly treated rotors to combat the wear, and that's just a band-aid solution, but better than nothing...or you could get carbon rotors, too...$$$$$$!

Too much technology for me...I'll stick with organics, which do have a lot of metallic particles in them...mostly copper, which is kinda soft, and less damaging to the rotors....
That's my story, an I'm stickin wid it.... :mrgreen:

I'll pay for quiet.

I once put "full" metallic pads as opposed to "semi" metallic on a 1 ton service van I had.
These pads we're suppose to provide better stopping power with less fading, fading was the big problem I had with that van. Those pads tore the bejesus out of the new rotors in very little time.
My mistake was not researching the pads better, I prolly should have used different rotors.
I ended up having to replace the rotors and went with cheapy pads to save the rotors and had to live with the fading.

On our bike I don't know. The rotors are a harder material, I believe stainless so they may hold up fine.

They sure are hardend, don't know if they are stainless, but they sure can warp easily from dragging pads!

Dont tell me that... My brakes are starting to drag once and awhile :head bang:

Don't waste any time on dragging brakes! I replaced all three rotors and the rear twice because I didn't have the time or money to fix them and it cost me just as much to fix them PLUS replace the rotors! Luckily, I had some leftover from the parts bike, but still had to get two from ebay. :crying:

Bubba LUV brakes! Brakes are Bubba's friend. Bubba think brakes are good.

It's so nice to feel I got new brakes that work right. :good:

If they drag enough that you can notice, it's definately time for new rubbers. And I think brakes are the easiest things on the bike to fix unless you're replaceing the rotors. I'm starting to hate removeing the rear tire.
