I have a Gen 1 car with the funky E-Brake set up that has very little fine adjust other that through the handle. After making the tension adjust through the handle as instructed the E-Brake cables seem too tight. The car rolls fine upon initial startup but after driving the car for a bit, using the brakes with the pressure building up it seems like the rear brakes are sticking some as I slow. I've had a slight rear wheel vibration at low speeds that I think is tied to the rear brakes sticking some. Is it possible that this low speed vibration & sticky brakes is tied to the E-Brake cables being too tight?

Thanks,
Glenn
