After a caliper rebuild to correct a dragging caliper, I switched back to OEM brake pads from EBC. They sound BAD like steel on steel Bad. Anyone else experience this? Also what elso could cause the the left caliper to keep dragging? Axle in all the way, calipers fresh, pins cleaned and regreased.
Ideas?

It's a matter of degree.
All disc brakes have rubbing.
It's a natural thing since there is no provision for retracting the pads.
Let off the brake lever and the pressure is released at the caliper. That's all that happens.

Ok, that helps, it just seemed to me to be louder lately. Hence the caliper rebuild.

Go for a ride. Put spit on your finger and touch the rotor... if it sizzles, there's a dragging problem, if not, probably not... The pin that the pads slide on should be clean too... I didn't clean mine up the first time I rebuilt my calipers, and the pads made extra noise...  -Mike |

Double check that the front axle is flush with the fork leg. Make sure you installed the axle and everything in the correct order (Just saying, I'm not even sure you touched the wheel/axle). BTW OEM pads are NOT EBC.

Did some more looking. With the EBC pads the rotors were smooth and shiny. Now with the Honda pads I see what looks like scrape marks at the inner and outer edge of the rotors on the braking surface. Kind of like a freshly machined surface would look. Could the new pads be roughing up the rotors????

They say it is possible that brake lines can go bad and collapse on the inside, causing brakes to hang. They weren't hanging before you rebuilt your caliper though? I've got a used set of front brake lines you could try as a test if you wanted... The manual sez brake drag can be: - contaminated brake pad/disc - misaligned wheel - worn brake pad/disc - warped/deformed brake disc - caliper not sliding properly -Mike |

The left was dragging, as verified by the jack up spin the wheel and remove the right caliper still noisy, reinstall the right caliper remove the left and no noisy method. Thats what prompted the rebuild of the calipers.

The EBC organic pads will nor harm any rotor, they also don't grab as quickly as oem, which suits me, less likely to lock them up in a panic stop. The other ebc pads are hard on rotors. Hoser

Rotors after use become slightly dished.
New pads, which are flat will tend to develop added pressures on the edges of the pads leaving additional burnishing (wear) on the rotor.
When you pads are fully seated and worn-in so they match the rotor your problem should pretty much disappear.
It's the edges of the pads that are causing the problem right now.
It's for this reason that the brake shops want to turn the rotors down on automobiles.

Double check the spring clip installation. I had mine in wrong for a little while, finally figured out that's what is was. They weren't seated properly...
Also, make sure there is fresh grease in the guide pin sleeve, and the sleeves are in their grooves and aren't torn . That gives a bit of "return" action.

There is more than 1 type of OEM [Honda] pad.. Our local dealer just tried to give[ well, sell] me a set with hard friction material and had to order the soft ones..

I've gotten the kind shrink wrapped onto a piece of cardboard from the accessory side of HDL, and I've gotten the kind in a parts bag from the Fiche side of HDL, both are labeled "06455-MV4-405"... I've never had them at the same time to compare them... does this sound like what you saw? -Mike |

My Local dealer got me 2 sets in plastic baggies, had to order them in, and took a few days. As to the rotors you're spot on Ricky-D. I pulled the new pads tonite and the upper and lower edges look like h3ll. Now to just brake them in. Thankyou all for the info and help. I'll try it for a bit to give the pads time to bed, and will let you know how it goes.
