I want to have four disc brakes instead of 2 wheel disc and 2 wheel drum? please tell me how to do that and how much it might cost?

 

hmmm on your lawnmower or what???ellaborate

 

you need to post more info. basically if you go to any place like ImportAutosalvage.com you can get the whole swap. but you will need a proportionoing valve to do it right.

 

94 honda civic ex... how do i do it?

 

call larry at I.A.S. tell him you want an ls disc brake conversion.
swap the supplied parts. this will be knuckles, and knees. you will need a proportioning valve off of an Si hatch. and possibly EG disc cables. i think the Ls are too long.
