Bonneville America Forums Forums Technical Forums General Tech Pulsing front brake

My front brake has a pulsation to it on a slow stop. If I get on the brake there is no pulsing but once I lighten up on it as I am about to stop it will grab and pulsate and bouce the front end. I would think if the rotor was warped that you would feel it at any speed. Anybody ever dealt with this?

Sounds like a warped rotor to me..

If your bike is still under warranty, Triumph will replace the warped rotor. They did mine (twice).

Sounds like a warped rotor to me as well.

Ya think?

yes I do.

If the rotor is warped is it ok to ride?

I expect you think this is a dumb question but hey thats me!

you can ride it but it will not be as safe and could cause the pads to wear uneven and faster. I rode my chopper for years with no front break and almost no rear break. That 66 stock Triumph rear break wasn't much.

My bike is in for her first service on Wednesday and I suspect a possible warped disc as I am also experiencing "pulsing" at the front when braking.

I will ask them to sort it out under the warranty.

Thanks for your response.

Only pulsates at slower speed with lighter braking was the problem with mine. They checked for warpage and didn't see any. Took it back again and they found the rotor had a fat spot causing the pulse. Rotor was changed and no problems since.

"Fat spot causing the pulse"?

Sounds like my ex

If it had a thicker spot it would force the pads apart causing it to pulse and would feel just like a warped rotor. If your bike is under warranty I would definately have it replaced under warranty.

Here we go again with the front brakes! Mine had thin spots but according to my dealer, not enough to be out for factory specs. Seems to be a common problem with the Speedys and Americas. There have been many threads on the subject.
