Bonneville America Forums Forums Technical Forums General Tech Front brakes pulsating. Rotors warped?

Anyone have problems with pulsating when braking with the front brakes? I have an 03 Speedmaster. Its not real noticable at higher speeds but when you slow down it is really bad.

PS If anyone have replaced their front rotors with EBC floaters or something I would like to buy your old ones

Not too uncommon. Hot stops will do it. How many miles on yours?

Mine have been that way for a while now, and I may let the dealer have it long enough to decide whether or not they want to replace them under warranty, or I may just keep riding. Even if they replaced the rotors it could happen again.

Cars and trucks suffer the same fate. At the Lexus dealership where I write service/consult, I usually advise out of warranty customers to NOT spend money towards a remedy unless they are very uncomfortable with the condition, or until they need the front pads replaced. When the condition is properly explained, most are more comfortable with what causes it and quit worrying about it. Though it can get to be a severe condition, usually it is only a mild case. If the vehicle is still in warranty, then obviously I will correct the condition. Believe me - my technicians would love to resurface the rotors on every one they see - often telling me of the condition that the customer had not even mentioned. The cars seem to shimmy more when braking from higher speeds, but like you, my SM bobs pretty good at lower speeds just before stopping. I'm not too worried about it.

Others here will have differing opinions - many have had the rotors replaced under warranty. You having an '03 may mean yours is over 2 years old?

The dealer replaced the rotor under warranty at the 500 mile service for the front bobbong up and down under moderate braking...

The dealership service writter seemed kinda supprised that triumph replaced it under warranty???

I just got mine dropped off at the dealer (4 days left on the warranty). I may be in for a fight if they wont repalce them.

The service manager asked if the problem would be noticable to the mechanic if he rode it. I said go ahead and take her for a spin. He then asked how far and fast does the problem occur at? I said go about 20 feet in the parking lot and hit the front brakes.

He took it for a ride and looked like he was on a bucking bronco when he hit the front brakes. He pulled it back in the garage and said Yeah there is something wrong.

Hopefully everything will be covered.

This is a known problem and Triumph are working to correct it. Depending on the dealer and what mood the Triumph rep they contact is in, it may be covered even after the warrantee is up.

My Speedmaster bobed just before stopping, was better at speed. Turned out that the rotor was not warped, but had a thick spot in it. It was replaced on warranty 2 years ago and no problems since.

Just talked to the dealer yesterday (Lexington, KY). HE said BOTH rotors were warped and that they had to call Triumph to get approval. I have the bike in the shop 3 days before the warranty was up but since they just got to it the warranty is out...BUT he said no matter what it would be covered under warranty just a little extra paperwork.

Seems like a good dealer so far. There are no local dealers around me. I drove 6 hrs to Chattanooga, TN to get the bike and had to drive 2 1/2 to drop it off at this dealer.

They said a couple of weeks to get parts etc. And of course it hasnt rained in days and by the time I get it all the rain we havent had will be here
