bliss ... I think I finally stopped the brakes squealing

[Mike Sands]

The dealer had a go and couldn't solve it, so I put up with it right from new, but finally got sick of it a couple of weeks ago. Since I had some copper slip I tried that but the silence lasted about 2 miles. I bought a pack of Wurth Sabesta adhesive lubricant (is that a contradiction in terms ) and that lasted about 10 miles. So I finally took the other advice on here and bought some 'Brake Disc Quiet'. Mind you in UK it's supplied in two small packs - I got mine here http://www.bitzforbikes.co.uk/-ref-10416-464.html
I also asked the new triumph dealer in Newcastle how to stop it and he said chamfer the edges of the pads.
So done that and applied the thin coatings of the brake disc quiet and so far things are looking good.

Duct tape on the back of the pads.

Would not brake pads "squeal" because they are glazed?

I spoke too soon .... the squealing came back after 50 miles. Not as bad as before but still annoying when you are coming to a slow stop at lights or junctions. The pads do look 'glazed' They are the original Triumph ones (done 8500 miles but have always squealed). Would another make perform better? I'll try emery-ing them this week. Would duck-tape cope with the brake temps?
Thanks guys .... any other solutions or tips would be welcome

Pads probably glazed due to being overheated. You could install a new set of pads and break them in appropriately.

Well, this is what we did when I AutoXed cars. The tape and adhesive would burn off but the strings would remain creating a buffer to abosrb the squeel (or something like that)

But, if they are glazed, you may want to look at replacing. And don't use the stockers, they're crap.

Make sure you apply a suitable lubricant to the pin(s) that go through the pads to hold them in place.

Yeah made sure I did that Mark - they are quite badly worn so I might buy some new ones. Also I haven't so far tried de-glazing the pads so will try that tomorrow. Anyone in the UK recommend some alternative pads? I don't ride hard but don't know whether that makes a difference.

You can put high temp silicon behind brake pads to help keep the high speed vibration down which makes them squeal.
If your pads are glazed they will most likely have tiny heat cracks in the surface of the brake pad. You can see them with good eyes up close or you made need some magnification.
The tiny cracks ampilfly the squeal.
Ill take a guess and say that the Disc brake quiet probably fills in the cracks...for a while.

that's interesting. when I take them out to deglaze them I'll take a look for cracks. The disc-brake-quiet goes on the back of the pad .... or at least that's where I have put it - duh
