Sprint ST (05->)

I'm wondering what experience people have of disc warping on the Sprint ST disc brakes.
My 2005 1050 Sprint has just done a sliver over 8000 miles but I've recently found out that the front discs are warped. I'd have expected to have had a lot more mileage out of them than that.
A mate who has a slightly newer Sprint 1050 also has found some warping on the front discs, but not as bad as mine, but still noticable.
What are other people's experiences? And is this a known or common problem?
Thanks in advance for your help.

I didn't have warped discs on the old Tiger, but the symptoms were the same, a pulsing at the lever.
It was mismatched discs and brake pads, which Triumph were aware about

Very common on Triumphs or I've been unlucky Daytona front discs changed under warranty 5000 miles and just had them changed on my 2006 1050 ST 7000 miles under warranty and it's not like I'm hard on the brakes.
I don't normally bother to do anything about until it goes in for a service.
Plus a few of my pack have had discs changed under warranty.
Always use the the gearbox and engine braking never had any new pads.
Get the dealer to try a post warranty claim you might be lucky as it's a known fault but I doubt it.
Some dealers aren't to happy about changing discs under warranty because when they send them back the factory say they are within tolerance and refuse the claim leaving the dealer out of pocket, which I don't get either they're warped or they aren't.

research other threads in here
Warping not likely. More likely to be uneven wear, leaving thick and thin bits on your discs.

A dealer has to obtain permission from the factory BEFORE they can change the discs. If they are changing them before this permission is obtained than that's thair own lookout.

My ST, '06 model bought Feb '07, has done just over 8k miles.
I can feel the brake lever 'pulsing' at slow speeds and there's a bad vibration when braking hard, to the point it feels dangerous.
I brought this up with the dealer at the 6k service, but they checked the discs and reckoned they were within maufacturers tolerances.
If they're within tolerance, Triumph won't accept the warranty.
I doubt the discs are warped as they float on bobbins, but as NET says, they're more likely to be worn. It didn't do this when the bike was new.
I fully intend to bring a mic home and check them myself. I won't be happy if I can't get something done before the warranty's up

Rob I only had bad vibration and bad juddering when coming to a stop, high speed braking you couldn't really feel it only a slight juddering on the bars.
New discs fitted all sorted no vibration no judder.
The head Triumph mechanic at Bridge rode it for 2 mins brought it back and said new discs.
The dealer changed mine ok how can the factory know how bad it is unless they send someone to ride the bikes at the dealers.
It's just another case of Triumph trying to side step warranty problems and there are lots of posts about that.

I assume the dealer has to pinpoint the problem, when approaching Triumph for warranty approval.
The big 12k service will come up in the Spring, I fully intend to make more of an issue of it then.

The juddering symptoms sound exactly like those I had on the Tiger.
Not warped, the pads were mismatched and would grab, release, grab, release etc, giving the impression of warped discs.
If the discs are indeed warped, then one will feel a pulsing at the lever.

I had not heard of this problem effecting Sprints, however this has been common on the America and Speedmaster cruisers. I was told that some of the discs are noth the same thickness on both sides from center, I was also told that moisture between the disc and pads over time effects the disc, making a soft spot. My experience seem to indicate the latter as most of the bikes i have seen with this problem are not garage kept, and the front brakes are not used very hard. What ever the case the dealer should have no problem warrantying the discs. My dealer is great about doing service bulletins and warranty work.

well I'm suffering here too. The warp developed early on and stupid me listened to the crack pot mecahnic explaining that it's because I'm a fat bastard the discs are warped. A warranty claim would be too hard and so why try at all right?
Well 60k km's + and the OEM discs are well and truely fucked (still using them too). the rotors have about 15mm lateral movement, in relation to the carriers.
I'm looking into replacing the carriers and the rotors at the moment.
I've found a guy in Nerang who will re-rivet them for $10 a rivet for me, but I'm suspecting the holes the rivets are moving in are shagged. therefore this would result in little improvement if i replace the rivets alone.
The other side of things is that the rotors themselves are warped, therefore no point in the above action.
If anyone wants to sell me thier discs (rotor and carriers) please drop me an e-mail...

you are quite literally on the other side of the world, however I do have a pair of good used discs as I put wave rotors on my bike last winter.

Not sure how that would help

The disc could be the same thickness and within wear tolerances but you need to either check with a DTI or take them off and put them on a surface table to confirm warping.
Although the disc will have a min wear thickness what is acceptable distortion?
Checking with a steel rule as a straight edge may give some indication but will you be able to quantify it?
Surely anything that impedes brake performance should be considered unsafe.

any GOOD Triumph dealer should be willing to ride and confirm the problem and have the warranty parts fitted in 3-4 days I would think. I have no idea why this is such problem seems a easy and quick fix to me. A dealer sold you the bike now it is time for him to serve his customer. If you bought second hand this is the dealers chance to get to know you and to make a customer out of this situation. In retail service and customer retention are the two most important goals. I have found if you can go into the dealer when he has a few customers on the floor and nicely explain the situation and ask for a solution they are more eager to please, because they have potenial sales in the back ground judging how they treat your complaint.

You in the usa have the advantage because Triumph are still trying to increase their market share and can't afford bad publicity so warranty work is done without question.
Which is how it was over here at the start but how things have changed.
I have had personal experience and know of 2 other mates who were treated the same way or that's how it seems warranty claims from the UK are now met with it your fault you've been miss treating the bike so the faults not covered.
Some people in the warranty either need the sack or go on a training course on how to treat people who have just spent £7000-£8000 on a new bike.

Amen to that! The warranty department are singlehandedly doing their best to drive customers away from Triumph with their attitude to customers.

That AND a new set of discs. Mine was only the SECOND one they had in the UK.
Have you read the latest "terms and conditions" re cleaning and pre-ride checks in the Triumph handbook?
"Wash and dry after EVERY ride"!!!!!!
May as well chuck out the warranty if they want to play it strictly to the letter.

I have to say I am fortunate in that my Triumph dealer was reconized as having the highest customer satifaction rating in the US by Triumph Motorcycles America. I know they work very hard to make all of their customer happy. I also know they go out of their way to push issues with triumph through. They are a single line small dealer so they have to make it on Triumph alone.
I honestly think this is a dealer situation not a situation with Triumph. Good luck, and if you can't get this dealer to warranty them you might try another Triumph dealer.

Gene it's not the dealers they go out of their way to be as helpful as they can be.
The warranty problems are the factorys fault and one individual in particular and his boss.
My dealer changed my head stock bearings on my old Daytona under warranty after only 4000miles and 6 months from new they were completely knackered.
They were sent back to him from the factory with warranty claim dissmissed the customer must have been stunting and abusing the bike for the bearings to go this quick.
I had never even popped a wheelie or done a track day on the bike only normal road use.
My dealer went the loser to keep me happy. well done Bridge Exeter.

It may be in some circumstances Gene, but in my case the dealer was excellent and tried very hard, but to no avail. They told me of other examples of problems they were having with the warranty department with other customers bikes.
Sadly my dealer is no more, as Triumph pulled the franchise from them earlier this year.

LOL - not much chance of that, during this summer
Bud - I tried measuring runout, with a DTI, on my RS discs - not so easy when they float on the bobbins.

At every service I hit my discs with a shot of brake cleaner. It is very dishearting to hear all the troubles folks are having with there bikes as i love my Triumphs and have had very few troubles with them. For the winter I am building up a customized Sp3. If any of you need a set of discs I have a pair sitting on the shelf. Cheers

Well I've just picked up my Sprint from my local dealer (North City). They arranged with Triumph for the discs (and pads) to be changed under goodwill (as the bike was 4 months out of warranty).
So many thanks to Triumph and North City for coming through.
Thanks also to all of you for the comments and advice.
