why is it that my brakes squeal only when I roll the bike backwards? 1979 850G

Hi,
Only backwards? Hmmm.
Normally, you will use a little brake/caliper grease between the shim pad (#3) and the brake pad (#2) so that it dampens (or changes) the vibrations to make them inaudible to human ears.
But I don't know why this happens to you only backwards.
Thank you for your indulgence,

dont go backwards!!! forwards is much more fun1978 GS1085.
Just remember, an opinion without 3.14 is just an onion!Comment

There is a shim missing in BassCliff's picture. It goes between the pad and the caliper (or piston) and on the trailing edge. This puts a wedge of effort on the pad. By going backwards, the wedge is on the leading edge, leading to chatter. Considering the ratio of how much time you spend going backwards compared to going forward, I would not worry about it.

Steve, do you mean this 'spring pad'?
I hope I'm not missing anything and that it just wasn't in the picture.
Thank you for your indulgence,

I wouldnt dare second guess Steve but that looks ok for the front caliper... the rear on the other hand has that directional shim

Now that I think about it, Mr. doug g never mentioned if it was the front or the back. Either way:

Oh, you're not "second guessing", you're just flat-out catching me in a rare mistake.
The last bike brakes I worked on were rears, so that's what stuck in my mind.
I had also changed the front pads on my son's car, and they had the c-shaped shims, too.
Yep, that c-shaped shim is only on the rear brake on the GS.

I have the old style calipers still on my bike. Duanage got me some newer style calipers but life has been so crazy I have not had the opportunity or cash to rebuild them and install on my bike yet.Comment

Pads are fairly new and they used to squeal when going forward and backwards and now with the new pads it happens only backwards.Comment
