for fear of doing any damage i stopped trying to take off the cap to my master cylinder.i want to bleed the lines and change rotors/pads(up front).does anybody have any helpful advice on bleeding?also,it seems that in order to take off my mas.cyl. cap i will need to take off the leafscreen or whatever you callthat thing that lets the air through into the car as it sits directly above the mas.cyl. is there an easy way to get the cap off?thanks
