In keeping with the above thought the bikes probably came from the factory with asbestos based pads which may not squeal like the modern compounds. Like the Gasoline that had lead in it, when one thing changes it has downstream consequences.

Hi Ian (Skud),
These are in a box labelled XELUS. Made in Italy. I bought these from a NZ company specialising in HONDA parts especially used from wrecking. But they import a lot of new parts.
Check on www.econohonda.co.nz. Contact is Malcolm Kirkby...or email parts@econohonda.co.nz.

Regards
Mark

The ones I found are "Fedoro" brand. I think I got them from M3Racing.
See SOHC4shop.com for info about the gadgets I make for these bikes.

Blood is thicker than water, but motor oil is thicker yet...so, don't mess with my SOHC4, or I might have to hurt you.

I started using brakes after I went through a pair of heals.   ;D Much better now.  :D

If a SOHC brake is working correctly they hardley ever squeel. Almost always there is something amiss... the brake swingarm is sticking or the piston seal groove has crap in it. Pads can help and the wrong pad seemingly does make it worse, EBC seems to be guilty on the forums quite often.

What is a decent pad to use and who is a preferred supplier? I keep hearing bad things about the EBC pads and I am getting ready to order new pads and a caliper rebuild kit for my cb750 k7.

On a side note - I just replaced a pair of squealing $50 pads on my minivan with the $14 AutoZone pads and my squealing problem has been solved. I was kind of shocked when I got them off because they where damn near new but I decided to swap them out anyways. Someone told me that cheaper pads are softer and tend to squeal less but all I know is that solved the problem. 8)

The rotor on my front end IS an aftermarket EBC fully floating rotor, and it still squealed. So that rules out the rotor being the culprit. I currently have EBC brake pads on the front WITHOUT using Dow Corning high vacuum grease. So far, after months of riding, I only get a hint of a squeal the first stop out of my garage in the morning. Then it disappears completely. I can tell you the master cylinder is the same. The brake lines identical. Due to the original squealing, I rebuilt the old caliper myself. . . a new o-ring and some cleaning . . kind of hard to mess that up too badly! and it squealed within the first couple of days (maybe the old caliper was worn in some way?)
The only things that are different since my brake squeal fix are:
1. Different, later model caliper
2. Did not use aerosol spray brake cleaner (which apparently leaves a residue on the rotor surface)

After being backordered for months, Michael at Vintage Brake just got a batch of Ferrodo Platinum pads in stock two days ago! Mine are already in the mail  ;D
That is another great reason to go with the later model caliper: Ferrodo doesn't make a Platinum series, aka "miracle" material pad for earlier calipers.
I'll give you guys a report after I get them installed and tested with some newly purchased Dow Corning High Vacuum Grease on the backs (you can never be too safe and I HATE F%#@ing brake squeal!)


Cheers,
stueve

UPDATE:
Just installed the Ferodo pads on my bike (after a few hours of measuring and head scratching). I was having issues with the brakes dragging. I measured the pad thickness in reference to the few month old EBC pads that were on there, and they were very close. The back of the pad, where the caliper piston hits the back of the pad, is a little bit more raised on the Ferodo, making the pad stick out a bit further than the EBC's. This didn't seem to be much of an issue, however, as with the piston totally buried inside the caliper, there was plenty of clearance and it wasn't mechanically binding once the caliper bolts were tightened. But it just didn't appear that the piston pad was retracting as normal. So, I removed the calipers again, and measured the diameter of the Ferodo pad vs EBC pad and the Ferodo pad was about .10mm larger. So, I was able to shave off that .10mm on my bench grinder, very carefully I might add, and tested. No dragging. The tolerances as the wheel spins are still a bit tight, but the bike seems to roll the same as before and does not drag nearly as much as before. I've got about 3 miles on it in stop and go and brief bursts of speed and it seems to be ok. I'm thinking as the pads bed into the rotor, the clearance will get a little looser. So, we'll see. I'll report back once the set up is broken in.
Oh, no peep by the way. Quite as a mouse. . .

Update:     Under suspicion that the front brakes were still dragging, I got the front wheel off the ground and checked wheel spin. I'll be a paranoid SOB if they didn't seem to be dragging still. The wheel would only make 1 rotation. I took the Ferrodo pads out and tried the old ones, and tried the same rotation test as accurately as can be expected, and the old EBC pads rotated about 2.25. WTF?

The interesting thing is, the static pad (inside, spokside) made by EBC has a dome on the back, where it pivots around inside the housing. The Ferrodo pad is completely flat on the backside, so it doesn't oscillate at all.

Any body else running these pads have issues/or can explain why Ferrodo didn't think it necessary to put a dome on the back side of the static puck, or can explain why they drag more than the EBC pads?

You know, giving it some more thought, having a non-oscillating inner pad means it's not centering and only wearing on the leading edge! DOUBLE WTF?! Anyone?

Is your wheel out of spoke true? Is it spinning dead straight? Mine wasn't and my old pad wore on the front unevenly and I had slight drag. I trued up the spokes as best I could and now I have no drag and (hopefully) even pad pressure and wear..
