Mastere Cylinder Honing

I want to hone the bore on my front master cylinder. I did a Google search for hones and found 180 grit and 320 grit hones. Which one would be best? I'm leaning toward the 320 grit to get a smoother finish.

Thanks.

I used WD40 and AAAA steel wool wrapped around a dowel placed in a drill. Worked like a charm every time i did it.
Make sure to clean out the master extrememly well with solvents & air before reassembling it. no need to buy expensive hones if you dont really need to.

Hmmmm. I like that idea. Thanks. BTW, is it critical to use WD40? I typically just use brake fluid. It seems to work pretty well as a lubricant.

thats fine,just make sure to scrub everything out really good with rubbing alcohal when you are done and dont get petroleum based cleaners on any rubber parts.
