Do you think it is the pads or rotor?

[Loki]

I installed the EBR rotor cause of a pulsing brake last year and I have done less then 5k miles on the new rotor. Well recently I noticed the front is pulsing coming to a stop, always the same place. I have looked at the pads from the outside and they look fine, and the rotor has no build up or heat stress marks. I know there is no way I have gotten the ebr rotor hot enough to warp on me.

What do you guys think could be the cause? Should I just buy new brake pads anyways?

What pad are you running with the rotor? When i forst installed my rotor i put those ****** "sixty" brade pads on and it gave me weird inconsistent brakings, almost a pulse but more of a grab and release.

On a side note: holy **** youre alive and posting!

Lol yeah I have been undgodly busy with working and schooling so I havent been able to do anything I enjoy really.

The brake pads on there are the stock brake pads. One reason there why I want new ones anyways.

Were the pads used with another rotor before the race?

In automotive we sometimes have issues when a cars rotors are replaced but the pads were not, causing most noticably noise and sometimes a grinding feeling. Often can be fixed simply by pulling the pads rough them up, do the same to the rotor. Motorcycles and cars completely different but its some input towards making a choice. Last week i switched from factory pads to EBC HH and im very happy with the very noticable difference.

Yes the pads were re-used. I just wanted to get some ideas before I spent 75$ on new pads.

Loki,

Do you have stands? If you do put your bike up on stands and spin the front wheel. Look for any sign of a warped rotor or rim.

Thats a good idea and I havent been free enough to think of that. I will do that tomorrow.
Thanks!

^to add to that you can check for warping by using something like a windex bottle or anything similar. Set it right next to the rotor and spin the wheel. If the gap between the bottle and rotor gets larger or it hits the bottle, it's warped.

The stock pads are known to leave a deposit build up on the rotor and cause a pulse feel... Its usually never a warped rotor and if you replace the stock pads with a different set make sure to use a scotch bright pad or something similar to get all the build up off your rotor. Your stock rotor was probably fine too but the EBR rotor is a lot cooler. Make sure you use the EBR mounting hardware and not the stock stuff.

My rim has a slight warp in it. The way I found the exact spot is I put the bike on stands, put a ziptie on the top mounting hole for the fender, placed a Dry Erase black marker in place and held it in place with two more zipties. Then I pulled the cap off and slowly moved it toward the rotor right at the lip of the rotor. I spun the rotor to find the LOW spot and moved it in till it ALMOST touched. Spun the rim and VUALA! I found the warped spot.

All good ideas that I will look at today. Also I do have the EBR mounting hardware on it as well.

Rotor isnt warped so I will take the pads off and either replace them or sand them down a little. I still dont understand why it would pulse at only certain spots if the rotor isnt warped.

 

[xtreme6669]

Clean the rotor (do a really good cleaning on it) and put a different set of pads on and you should be good. I went thru the same issues!

Thanks. Ill update in a week or so when I get my new pads in.
