Hi all,
My Vintage Electric Cafe bike has developed a metallic knocking sound (and accompanying pulsation that I can feel through the handlebars) coming from the front wheel when applying the front brake. It only happens with the front brake; if I apply the rear brake alone, I do not get the knocking sound or pulsation. It also doesn’t happen while coasting: only when applying the front brake. And the sound gets louder/stronger in proportion to how hard I’m apply the brakes. The brakes are “Promax Lucid Hydraulic disc brakes.”
I am a complete bike newbie, so I lack the tools and skills to try to diagnose or fix it myself. I’m nonetheless wondering what might be causing this, both for my own learning and so that I can tell my local bike shop what specific things to check.
Thanks in advance for any insights!
