Well apparently there is a return spring and an assist spring. (I took a break from the frustration for the holidays)I pulled out master cylinder, and now when I push the pedal (with my finger even) it kinda slams to the floor and stays. So my 'assist' spring seems to be doing its job but I can't locate the return spring nor does it seem do be doing its job. I see in the diagram where it goes but when I look at my pedal I can't see any evidence of one ever being there. Is it enclosed in the bushing or wrapped around it like everything I find suggests? I am sooo confused:-)
