What is the best stone grit for honing wheel cylinders. 320 or 240 0r 220. ? 220 seems to be the most common for the Lisle 10500 2 stone hone. Also, it was posted here on he Fordbanr that using regular cutting oil gives a better finish than WD-40. Is the cutting oil referred to the old sulfur based stuff. I still have a gallon of that. Thank you.

It depends on what kind of shape the bores are in. It doesn't hurt to have a heavy cut on bores that have light pitting then finish them with a lighter cut stone. If there is no pitting then you can use a finish cut. If pitting is bad, they should be resleeved. I use a light oil around SAE 10 for honing.

Thank you. The bores look good, any recommendation on stone grits ?

If they just need a clean up, I'd use the 320 grit. The smoother they are, the longer the seal cups will last.

I just used brake fluid with the whl cyl hone....from harbor freight. My cyls were about as bad as can be without tossing or sleeving them. What to lose, so worked them over/over/over. Put new parts in and they worked perfectly ..as in didn't leak

!

There is/was a thread here , back when, with pictures showing the extent of the mess/rust. Regarding the grit...your choice. Three stone hone is what I used.

Wheel and master cylinders are still available at reasonable cost, and a much better choice than honing. Sleeving is most common with cylinders that are rare, as the cost is usually higher than replacement. As you can't see the entire bore, honing is often incomplete. We had to do it many years ago when parts were scarce, but leaks were common.

They may be readily available at reasonable cost for good reason, they are made where people don't give a damn about quality and the stories continue to multiply. I'll hone the originals that are marked made in the USA, as I am an old Yankee and they are my brakes that I depend on.

When I first got m 48 it was supposed to have had a new brake job. One of the new wheel cylinders leaked and ruined the lining. I replaced it with one from Napa and have been fortunate enough to have gotten one that works. Both were from China.
