Hi ,
The brake lever on my wife's bike has started to pulsate slightly when the brake is applied and I know this is normally caused by the disc warping but are there any other reasons for this to happen?
Thanks

Re: Pulsating Brake Lever

Re: Pulsating Brake Lever
Rode the bike into see Jason Kain this afternoon, no signs of a warped disc, so he suggested I remove the pads and take any glazing off with emery paper. It appears to have done the trick.

Re: Pulsating Brake Lever
Sanding the pads is good, also sanding the disks will help using 400 grit wet or dry sand paper.
Jim Beam also helps.
