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

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.

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