After I had my STX for about 2 years my brakes started to do this weird pulsing thing. It was under warranty, so I had it taken care if. Now it's starting to do it again(2 years since), but I'm no longer under warranty. Sound familiar?

 

Sounds like warped rotors. Time for a brake job.

 

I think a seized caliper piston or slider pin will cause a pulsing pedal if they are left long enough.

Pop a wheel off and poke around.

 

When I had the problem fixed before, the mechanic told me the rotors were warped. That was after only 2 years. Now it's doing it again? Is this just going to be a reoccuring problem?
