Pulsating Brakes After Caliper Rebuilt/New Pads
So I noticed when replacing my pads this winter that the bottom piston in both front calipers were seized. They were both pretty much completely pressed in. I took the calipers apart and cleaned out all the gunk and fixed the pistons. I put in my new pads, bleed the brakes, and put my old rotors back on. I measured the rotors and found they are in tolerance, but honestly not by much. I only measured one spot though assuming they were not warped because the bike did not make any vibration or pulsating before I changed the pads.
Now at any high speed braking there is violent pulsating in my front brakes. At low speeds it only happens when I put a good amount of pressure on the brakes for a quick stop. At very low speeds there is no pulsating when stopping. No matter when it happens I do NOT feel it in my brake lever. I was under the assumption that if the rotors were warped I would feel it in my lever.
Could air bubbles in my fluid cause this? I bleed them, but maybe not good enough. Could the seized pistons have caused uneven wear of my rotors from last season, and now that I have both pistons pressing on the pads this is the problem? Any input is apprecaited.
