Squealing brakes

[GS750GUY]

I did a search on this subject and don't seem to find much dialog regarding this.
I have a 78 GS750EC and just replaced the brake pads on both front and back with Tuf-Stop Heavy-Duty Ceramic pads. The new pad surfaces appeared to be already scuffed right out of the package so I did not sand them at all prior to installing them.
The rear pads squeak only slightly and I feel they will probably quiet down when the pads get seated in. However, the front pads are another issue. They don't just squeal; they screem something aweful. I imagine everyone at an intersection knows I'm coming when I pull up to a stop light.
A friend told me that his service manual says to allow the new pads to settle in for a 100 miles or so and they will quiet down.
Is there any validity to my friends advice, or is there something I could do to quiet them down?

Thanks for your advice. I imagine this must be a pretty common issue.

Did you lubricate the back of the pads?

Did you lubricate the back of the pads?

No, I didn't lubricate the back of the pads. I tried to follow my service manual to the letter and I saw nothing mentioned in the manual regarding squeak prevention or lubricating the back of the pads.

If I need to lub the back of the pads what should I use?

Thanks,

The early type calipers with the round pads are a lot more prone to squealing, not sure why.

Not much help, I know but if you put on some later style calipers it will stop better too.

Buy some Disc brake quiet from Kragen or somewhere. I have the CRC branded stuff and it works great.

Sounds like you need a new manual. The factory Suzuki manual for the GS750 calls for greasing the back side of "pad #1".

You can get the disc brake quiet at Autozone or similar. It is 99 cents and they sell it at the counter in a little packet.

Disc brake quiet is your friend

Just pop the pads out, clean the back with Brakecleen, let it dry and put a coating of the DBQ on. Let it dry for a few minutes, then reinstall the pads

You probably should clean your discs with Brakecleen also while you're waiting ofr the pads to dry

The Suzuki manual is very specific to only use brake grease on the no. 1 pad, not the other. Read the manual before slathering these parts with grease.

The early round pads will start squealing when the slide bushings start getting loose.

Worked like a champ so far

Hello All,

Just wanted to let you know I had good luck with this procedure on my GS550ES. I had a set of EBC pads in the back that sqeaked their whole life and I just replaced them with some Tuf Stop Ceramic pads that squeaked worse. My SBS pads in the front have also squeaked since the day I put them in too. I took the rear pads out, cleaned them, the caliper, and caliper pins with brake cleaner. Then I used a q-tip to put a light film of synthetic brake caliper grease on the entire back of the pads, the sides of the pads that nest and contact in the caliper, the area on the back side of the shims that contact the caliper piston, and the pins that hold the pads in place in the calipers. Took it for a test ride and it was quiet as a mouse. It was SO nice!!! Hasn't been like this in 15 years!!! So I took the front apart and did the same procedure. Worked just as well there too.

About a 100 miles so far with no brake squeaks and I can't express enough how nice it is to not have that annoying sqeal!! Thanks guys for the great advice!!

Have a great day,

Ryan
