Hey Guys,
Just realized what a problem I've had for years (and maybe 70k miles) is. When I push the brake pedal really hard the brake booster actually separates at the seam that runs circumferentially around at the very top and makes a squealing sound. Must be suction I suppose but I didn't test for that. I just ignored that sound years ago and adjusted how I brake so that it didn't make the sound and forgot about it. Now it seems to be getting worse. I wonder if sealing that seam with silcone or something would be just fixing the sympton. Do I need a new booster? It's all original brake booster and master cylinder with 260k miles on it.
