I think u modifly the push rod is same as u shift up the brake pedal higher, should help a bit for heel and toe, but the force still not smooth.
It happened on mind, I brought a 剎車真空倍力器，it just a metal cylinder with a vacuum gauge, install between engine vac hose to brake servo, the theory that should increase the volume of the brake cylinder. I haven't install it yet, duno it can help or not. |
