Speed Twin - Squealing Front Brakes.

Yes.

 

Yep, mine squeal as well, although it's not constant.

 

What is your mileage Bryf?
I've just had my first service so got a couple of hundred miles to do yet.

Are you particulary heavy on the front brake Wessa? I doubt it, especially while running the bike in. As you say, warped discs and worn pads at 700 miles is not right so I'll be interested to see how you get on with the warranty claim.

Thanks for the warning, not something I'd have thought to go wrong with Brembo brakes.

 

I've done around 2300 miles but probably started doing it around 1000. As I said it's intermittent, as yet I have not found it a problem, other than a little irritating!!!, but importantly brake function is still great.

 

My front squeaks one day and not the next, it all looks good and works fine so not bothered at the mo and only done 800 miles so far. The other thing i noticed people are saying a lot is the rear wheel squeaks as you push your bike along, when fixing my rear puncture i found that both rear spacer to seal joints were dry so lubed them and noise has gone and i also did Su's bike as that squeaked as well. ( Get your act together Triumph )

 

Triumph seem to have had an aversion to grease for many years

 

My brakes squeak intermittently and hove done since about 7-800 miles. Just got back from an 1100 mile French trip and they seem to have stopped for now. Total mileage 3200. Taking her back in for a recall soon so will ask them to check.

 

Cooper grease might fix it (obviously not on the FRONT of the pads)...

 

What is the recall you are taking it back for, I haven't heard of any yet?? (I am assuming it is a Speed Twin)

 

I am going in to dealers for new exhausts under warranty on 6th Aug will have a word and get them to check brakes at same time, cheers

 

As stated by Triumph -

The coolant hose between the radiator and expansion tank may have been misrouted during assembly. A misrouted hose may come into contact with the exhaust header pipe, potentially causing damage to the hose.

If you look a bit further on the web they recalled 700 + in the US for a similar thing.

 

To be honest it looks fine to me but with the brakes making the odd noise as well I'd get them to look at it. It's not far, 12 miles, and I can always take something out for a spin while they fiddle, then a bacon roll, sausage roll, coffee or two....

 

mine squeal as well. good to know it's not just me! has been driving me mad.

will speak to jack lilley and see what they say.

 

Just learnt something new. Seen a post on PHd's Bike Banter about warped discs. Some comments there that suggest that the disc bobbins (that allow the disc to float) can corrode onto the disc or bind causing the symtoms of a warped disc. There's a handy video

on freeing up the bobbins which might be a good idea to try before checking the run-out on a dial gauge or similar. Or pursuing a warranty claim.

"Bobbins.....
Was same on my Hyperstrada and Multistrada.
Light brake pressure. Pulsing
Hard brake pressure. Ok
Freed off bobbins. All ok at any brake pressure."

However....Matt on his The Workshop channel says doing this is b*ll*cks..


And Delboy explains that if the bobbins get rusty or clogged with brake dust and stop the disc from moving, it can then potentially warp.


You decide. I'm going to keep my bobbins free from crud. Bobbins are there to allow the disc to float and to stop the disc warping.

But it is a bit more complicated...

I've known the bobbins to seize on other bikes too, when I had my GSX1400 it was common on them but regularly cleaning and freeing the bobbins definitely helped avoid the problem. Something else to try to is if you brake hard then avoid holding the brake on after you've stopped, the theory on this is that when you brake hard everything gets hot but if you hold the brake lever on after you've stopped it retains more heat in the disc where the pads are in contact and as the rest of the disc loses heat this can lead to warping.
