Brake Imbalance
Posted: Fri Nov 12, 2021 5:01 pm
My right front tire always locks up first in a hard stop. Last winter I disassembled everything (front and rear), cleaned it all up, replaced the front pads and rear shoes and re-assembled. It all looked good (no leaks, all cylinders were OK (they were brass sleeved years ago when I replaced the seals).
I pulled it apart yesterday and noticed that the right side dragged more than the left when turning the tire by hand. The inner pad on the right side was worn more than the outer pad or the pads on the left, which were all about the same. The cylinders look like they did last year (good) and still no leaks.
I can't see what's causing the inner piston to drag, and I'm wondering if that's what's causing the braking to be biased to the right. The only other thing I can think of is the pin in the center of the cylinder that the piston presses into. It doesn't seem likely that it would be causing the inner pad to drag since the pins in both the inner and outer cylinders have about the same amount of axial play. What is the purpose of this pin? Any other ideas on things to check? I don't feel like replacing the seals is going to address this.
Thanks for your input.
