Does it attach right to the pedal eliminating the other pieces of linkage? If so what to I hook the spring up to so the pedal returns?
(1) yes (2) no spring needed cuz the M/C internal spring does the return. EDIT confirm that your MC choice has the circular recess in the rear piston "thimble" for the pushrod & piece of neoprene retainer (that slips on the pushrod recess behind the end rounded nub) to lock into & if you do not have the neoprene piece a snip of vac line from your parts house works fine. The ones that come with some MC's have a shallow notch lengthwise in it & not sure if that is to let air excape as you lock it into the thimble groove or if it is just a mfr thing that happens when they cut it.
Folks, please think before you follow advice from Internet forums.
Robert, you are giving out bad advice again.
That notch down the side has a specific purpose, do you know what it is? It’s not there on accident.
Get the correct piece for the job, this is a brake system. Have you seen what happens when the pushrod comes out of the master Cylinder? It’s dangerous.
