    He's using far too much copperslip grease Tosgha. As seen at around 1 minute 20 seconds.
    If you change your pads. Just add a thin smear of grease.

    Use high temperature grease not copper slip

    I must have the only speed twin that doesn't suffer from brake squeal:)

    Don't worry you'll notice I put a question mark in the title. I don't actually have a squeal problem on my bike, I spray the discs and brakes after every ride and nothing has happened up to now, done 1500 miles. But yes I laughed when I saw how much copper slip he had used. Also as he had changed the pads as well he doesn't really know which has provided the cure , the grease or the new pads.

    i cant see how brake pads can be the problem i read somewhere not sure if it was on here that some people have had to change discs and even the wheel to cure it which suggests the disc is warped or the mating surface on the wheel is not true.

    All in all a rather poor video, as previously mentioned he was rather over enthusiastic with the copper slip and also is comments about the calliper bolts is worrying, should make it clear that a torque wrench should be used to get the correct torque on these vital bolts.

    I traded my speed twin within a few months of ownership because triumph would not provide a fix for the squealing brakes. I have said it in prrevious threads, it should not be down to owners to fix their squealing brakes :imp: on a £10k+ motorcycle. Triumph should recognise that there is a problem with this bike and provide a fix... rant over

    I also noticed your spelling of brake. It didn't instil confidence. So I figured it was worth mentioning the excessive amount of copper grease being used in the video. Only trying to help & stop you making the same mistake Tosgha.

    yes spotted the spelling error before I submitted it but then my laptop crashed and it posted the original for some reason. I corrected it straight after 'onest guv'!

    A thin smear of copper grease has been used on the rear of brake pads for decades & to great effect IMHO.
    In recent years I've read conflicting stories about its use (always on the interweb)
    I'll continue to use it until I experience any of the alleged negative effects.

    As the guy in the video said. Often the squealing only starts at light levels of braking.
    i.e. when the pads aren't being clamped tightly against the disc. So they are allowed to vibrate in the caliper & resonate. Causing the annoying high pitched squealing sound.
    If the problem was with the discs. Then owners are far more likely to experience issues when the pads are clamped tightly to the discs.

    @Wessa
    Did Triumph try the copper grease idea? Or did they just keep throwing discs & pads at your bike.
    I still find it bizarre that they couldn't cure the problem!

    Nope they cleaned them a few times, then replaced the discs and pads under warranty. All attempts created short term fix, but the problem returned. I agree with you @Dozers Dad cannot see why triumph cannot fix the problem :mad:

    Strange they just didn't provide a set of anti squeal shims to go between the pads and pistons. It's common practice in cars, would cost next to nothing and with a dab of copper grease solve the problem

    It’s weird that it’s not all Speed Twins. 1300 miles on mind now and not a squeak out of the front brake.

    Mine squeals like a banshee!

    I love the bike, let’s be clear. It’s extraordinarily good, and I have owned a LOT of outstanding motorcycles.

    I’ve tried different pads, deep cleaning, even took it to the dealer and said “fix it I don’t care what it costs.”

    But no luck. It’s a new model, they will sort it eventually. ;)
