EBC BRAKES

[rangernight]

Finally getting to the fat girl again----In the pursuit of the Phonex, I discovered that some how I had damaged the right side rotor in the  crask , I bought EBC rotors and HH pads, spent most of the morning putting them on, took her for a test ride and heard what sounded like grinding, on the stand and spinning the wheel no sound at all.  I looked at the rotor and it seemed like the pads were gouging into the rotor . So, I ask----has anyone had this situation happen?
I did put the FG on the stand again and checked it all out, clearance between the calipers and the rotors are the same, the wheel & the rotors spin true ---this has me very baffeled!!!!!! Anyone got some Idea's???????  Thanks as always for any input!!!!!

ebc makes several types of pads. don't recall which is recommended for the valk.

i think you have the wrong pads.

You cannot use the HH pads with the stock rotors you found out what will happen. If you want to run those pads that do stop better and perform better you need to change out the rotors. The EBC rotors are made of a different metal and able to stand up to the harsh pads but even then you may notice some scoring. I have the EBC pads and wave rotors and love them. EBC does make other pads you can use but I would stay with stock especially when the bike has started that way. If you insist on staying with them a few hard stops may help the situation.

I do have the wave rotors, they are scoring, I just don't know if this is unusual. They do make some grinding sounds at times.  Just have concerns---Thanks

My stock rotors warped on me from some pretty hard front only braking.

Ordered EBC rotors and pads from across the pond.

Installed them, and rode off.

My son rode it a few days later and said dad, you got a rubbing sound up front.  Since I've lost about 60% of my hearing, I never heard it.   This was like 150K miles ago.   In that time I've put on about 3 sets of EBC pads and no problem.

I admire people with good hearing, but at times I think ya put too much into a little scraping sound or a little squeak, which probably 80% are stand noises.

Get on the Phat Lady and just enjoy the ride.

The EBC organic pads will not hurt the rotors, also makes the brakes less sensitive. That means you squeeze them a little harder to stop. No surprise lock ups.  Hoser

RJ---Thanks for the info-----did yours seem to scour the rotor? The factory rotors seemed so sooth, and the EBC rotors seemed so rough.  They are releasing with no problem, just the sound
I will just have to see how they do with some time on them, I gave thought to putting back on the old pads the old pads for a reference???

Sorry should have seen the rotors in the first post   As for the scoring mine did the same thing and still do they are not perfectly smooth and have been that way since I installed them. The noise will be in the beginning try a few good stops and all should be ok. Mine don't make any noise at all. Maybe tomorrow I will take a couple of pics its a little hard to get the resolution fine enough to see the grooves. I tried to call EBC and really wasn't able to find any real contact number. I have about 20k miles on mine and they have worn very little and that is through a pad change also. Other than the surface having the grooves in it the surface is wearing evenly as far as not concave and maybe a couple of thousandths off the the overall thickness.

I have the ebc organic in the front for about 400 miles now. I think they stop better than oem, less dust, more initial bite, and give the rotors a nice shine.  They made a little chirp noise at first but it went away after about 100 miles. The only thing is the pad is not very thick and may not give long ware. They are cheep so what.  Are the pads the same for front and rear? The rear pads are thicker.

[rangernight]

Thanks for the pics, mine look close to what I see in them.  I did get a call back from the EBC rep. late yesterday, he advised that the brake pads some times have the wrong mixture of material  and are too aggresive for the rotors, he stated that he may have to send me new rotors , I will find out today hopefully?????? We will see ---Thanks to all that replied

[rangernight]

UPDATE: I recieved 2 sets of brake pads from the EBC rep. . When I removed the pads sent with the rotors you could run your finger around the edge and feel where the pad had pancaked out, it was so hard it had caked to the edge. On the test run with the new less aggresive brakes it worked great I checked them often and after the ride I could noticed that they were in fact smoothing out the rotor from the prior pads---so my hat is off to EBC brakes and the fact that they want happy customers----seems a rare thing today.

The pads on a new Valkyrie were NISSIN TT2501HH.  That should indicate a sintered or "HH" type pad is the correct one.   My bike still has those pads.  The rotors look fine.

It makes me wonder if excess rotor wear is a "Sintered material" problem, or EBC-specific.

[Valkpilot]

I have the ebc organic.... more initial bite...

According to EBC's website, this is only true if the organic pads and rotors are already heated up.  Under normal (street) driving conditions, organic pads will not bite as quickly.

They are much easier on rotors though.

Most braking systems will lightly sweep the rotor with no pressure on the lever. You really don't want space between them at rest because that translates to a big load of nothing in the first bit of lever travel. Anyone here remember the old spring retracted drum brakes on some old Brit bikes? Terrifying until you got used to the dead zone and even then they could cause you to suck your entire seatcover into your ass in a panic situation.

The EBC rotor and EBC pad combo should be fine. You MIGHT have a hard piece of metal in your pad causing a gouge. But some running in is normal with metallic pads. It's tough to tell if what you're experiencing is normal without seeing it.
