Update on this stuff. The best i can tell what this stuff does is act like some sort of a lapping compound of sorts. I
believe it just soaks into the pad and helps to deglaze your rotor(s) which is often a source of squeal for any vehicle. That would explain why the results are not 100% permanent. While it has made a drastic improvement compared to before,it did not completely eliminate any noise,it just lessened it drastically.
I'm trying to figure out how to describe all this so I'll just use a scale of 1-10 to help explain.
1-silent
10-holy $#!t,thats loud!
Stock rotor with factory replacement pads - 5
Stock rotor with sintered EBC pads- 10
Stock rotor with sintered EBC pads & Protex- 1 but slowly(~400 miles) turns into 3
Now for the next part. Recently a question was raised concerning pamping shims. Whatever they are???
http://honda-cb750-s.456789.n3.nabble.com/Front-wheel-Pamping-shim-questions-td4039044.htmlSo tonight I got a roll of heavy gasket paper and made a pair of these pamping shims. With no other changes my current brake squeal rating of 3 turned into a solid 1.
Since temperature seems to affect the squeal I rode around for about an hour in the mountains earlier today to see what level i was squealing at today. Still a solid 3,maybe a 3.5 since it was a little humid out today.
I already had the shims made up and it took me about 30 minutes to get them on and go back out. Same temperature/humidity conditions. All other aspects were the same. Shoulda been a pretty equal test.
Under most all braking conditions the shims brought it down to a 1 again.
After riding the exact same loop at the exact same speeds as before the brakes never got louder than what I would call a 1.5 or a 2. They only made a little bit of noise when I would jump on them fast when they were cool (after a long period of non-use).I would occasionally get a touch of squeal right before coming to a complete stop most all the time. Probably a 1.5 on the uber-accurate squeal scale.
I'm no scientist,I'm just strictly experimenting here,but these shims really seem to have made a real world difference. I think perhaps it has to do with the fact that it gives the rotor a ''soft bed'' to lie on which is helping to reduce the vibration/squeal. Just to take it one step further I plan to make a little shim to go under each washer where the mounting hardware for the rotors are. If some isolation is good,then more is better,right?
So once again,standby and I'll report back after logging some miles to see if any of this is legit,or if I'm just wasting time.
