Disc Brake Issue
I have a a Trek Checkpoint ALR5. It is equipped w/hydraulic disc brakes, Shimano 105 to be exact.
My problem occurs when riding, I spot an unavoidable bump or pothole and I apply the brakes, There is a rather violent vibration in the front brake after hitting the bump/pothole. It's as if the front brake is braking and immediately fading. The vibration continues until i release the front brake. When I engage the front brake again, on smooth road, front braking is normal. I do not have the same problem w/the rear brake.
I am a large rider. I'm 6'4", weighing 200 lbs. I've read that cycling disc brakes are susceptible to fade for large riders, but haven't come across anything like what I'm experiencing. My LBS has checked the front end integrity of the bike with no negative results.
Any thoughts would be appreciated.
Thank you
