Schming, I suggest rounding off that leading edge of those rear brake pads to eliminate that unbearable squeal.

I'll give that a try before I change out the disc to a stock one.

Two coats of CRC disc brake quiet spray didn't help a bit.

Think I drilled too many holes in the discs, the rear is unbearably squeelly and grabs at slow speeds.

NICE .................
Some great scenery for your 55 mile shake down run.

Looks like you are all set for XS East and a summer of riding.
Hope putting a 30-40 degree bevel on the leading edge of those rear brake pads takes care of that squeal. Let us know if that solves the problem.
btw: I assume the shiny brake pad abutment retainer clips are in good condition with no pitting, not bent etc.

That's Racoon Lake, Jeff. We camped there one Autumn and found out why it's named that, little SOB's stole the burger buns off the table as I was grillin' on the other end.

Sanded the pads down to a 35 degree relief angle, and did an 80 mile test run, it helped the grabbing but still squealed just not as bad and not at every stop like before.

The hardware is all new and in great shape.

So should I round them instead of the sharp angle as motoman suggested ?

the Rotor?

from looking at the wear groove on the brand new pads it looks like there is a protrusion on the rotor about 1/4" in making that indention in the pad? Does the rotor have a ring around the rotor? not rosie or collar, the rotor Not sure what the other guys think but seems i've solved mystery squeaky brakes problems by sanding off any ring on the rotor. As you said, all new parts. Adding a little rounding to the leading edge (direction of rear wheel forward travel) of the pad as motoman mentioned might also help a bit. But i'd look for any oddity on the rotor itself and maybe sand it off so the entire rotor surface is smooth with no obvious raised ring that isn't wearing as fast as the rest of the rotor surface.

Squeeeelllesss !!!

After rounding all sharp corners on the pads the rear brakes were better but still squealed so I changed the disc rotor to a good stock one and "The Squeal is Gone and The Thrill is on

Note to self don't over drill the discs just cause it looks cool

84 holes seem to take to much mass that is needed to absorb the heat

Good News .........

I was wondering if you would find a fix before the XS East Rally. Phew, made it. Wouldn't want a nickname like Squeaky. I wonder what the optimum holes drilled count should be.

Thanks for the update. Enjoy the Rally

Jeff

This link to drilled brake rotors by Ken Talbot is where I got the pattern.
I doubled it 'cause I liked the look but all show no go.

I don't think others had any problems with Ken's original pattern.

Can't really see the rear disc rotor on my bike as the hard bags hide it so all good to go, West Virginny here we come

Ben, I would say your FANTASY is sitting in front of that sign.
