Speed Twin - Has Anyone Sorted The Squeaky Brakes?

...regarding the comment on owners trading them in.....it's happening...I bought a used Speed Twin with 400 miles....and it squeals

 

I read recently in another thread about fork alignment that after realigning the forks using the Delboy’s Garage method that the squealing brakes stopped.
And it wouldn’t surprise me that it’s simply a matter of proper torque of the pinch bolts and axle nuts. It’s worth a try, and probably a good idea to check these anyway, since Triumph Quality control at assembly is definitely inconsistent...

 

At over 5000 miles no more squeal. It stopped when the new EBC pads I ordered where delivered. I am not kidding. I may get a squeak every once in a while but nothing like it was. Good thing is I have new pads when needed.

 

You are absolutely right. It is impressive in not accepting there is a design problem with this system. If you search in forums, this problem is around the world and Triumph is exchanging discs, pads and wheels, all under warranty. This is costing so much to them, not mentioning the company´s image. I bought my bike around 5 months ago and the squealing is there since day 1. I expended money and time tying to find a solution. Spoke with engineers and Technicians with knowledge in braking system and all agree there is a problem with the system. One of the pads I bought was AP-RACING and through the company that represent them in Brazil, I was able to get their opinion on this subject and they also agree with the overall opinion, that there is a project failure. I do not not think this should be a problem, but this system was designed by Brembo in 2001. When I found it, I wrote to Brembo and got no answer back. Well, after this saga, including several complains with the factory in Brazil and with the dealer with so result (the only answer I got from the dealer was that there is nothing do unless the factory order anything or issue a recall. Already pissed off, I wrote to Nick Bloor and several other possibly VIP inn Thriumph´s world and as a result, in less than 24h I got call from Triumph asking me to make a visit at the dealer. Surprisingly, after 2 day with my bike, they found my discs were warped. So, last week the exchanged my two discs and all my pads, including the rear pads as well. Just to understand the process I went through to try to find a solution, if anyone want to know, I made several observations on a Youtube post of another ST´s owner. Take a look there.....

Wheel, Fork, Disc, Caliper, Pad Alignment ??? (May be worth trying if everything else OK)

Should the brake caliper tightening procedure not be followed after changing to new pads ?



Regards

 

Very interesting. I understand the procedure of holding the brake while tightening the calliper´s screw ( I do that on my mountain bikes with 4 pistons disc brakes to align the calliper and pads). But in Speed Twin, the calliper has a fixed and unchangeable position. Only the pistons are responsible to accommodate the pads on the discs. So, fix there is any warping at the disc, it is reflected immediately. Screwing the axle and aligning the legs, might be worth in trying. Well, since I started with this problem, I never considered the alignment of the legs. But coincidentally at the same time Triumph exchanged my two front discs and pads, I installed a front fork stabilizer (PART NUMBER: A2041204) and I did not experienced any squeal, in 100km and the brake is better than the day 1. I know it is too early to say anything about this as I need to run mor 500km to be sure if the problem is left behind or not. I will post here the results in the next weeks.

 

Please excuse me if this has been asked before
Do the pads on the Speed Twin have shims???

 

I'm guessing not so maybe a case of saving those empty baked bean tins.

 

No. They do no have. And I am producing it at home just in case the problem is not solved with the disc change.

 

Right well I think it’s Feckin ridiculous that Triumph and more importantly Brembo haven’t supplied ALL Speed Twin owners with pop on shims for these bikes
FFS shims and a dab of copper slip is probably all it would take

 

Feck it
I have to say it again I CAN’T BELIEVE THAT NO SHIMS WERE FITTED FROM THE START

 

I believe the braking system on the Speed Twin to be sufficiently capable of stopping me....why would a 3rd party (free spirits) be selling an upgrade for a model that has only been on the market for a couple of years? Are they selling a solution to the squealing brakes?

Wow, that’s a sharp looking setup. Triumph should comp this system upgrade for all Speed Twin owners.
Ha. Not holding my breath they’ll do anything...

 

Shame on triumph for allowing their customers to have to spend a penny/cent on fixing a problem which clearly is theirs

 

Bigger rotors? If I apply the stock brakes too firmly I slide up the seat until I hit the tank. A brake upgrade for me would be a cricket box (with or without a Triumph logo on) it just so I could use all the braking power available without suffering..

 

I would ask triumph to pay for it

 

For the second time since I acquired my ST in August, I dropped it off with the dealer - complained vehemently about the squealing... stated that its a known problem. My dealer said they'd check with Triumph....more to follow....
