If you have a few minutes to spare, it's easy to give it a try with a hone to see if it will clean up. If it does clean up (no scratches or pitting remaining), then a rebuild kit to rebuild all four front slave cylinder is only about $25. The brake cylinder hone is $6.95 from J.C.Whitney (Jan 04). This will last through a few dozen cylinder honing jobs, and replacement stones are a few dollars. Be sure the brake cylinder hone will fit into the 7/8 bore of the master cylinder (quite common).
Vasculitis is blood vessel inflammation that causes fever, pain, local tenderness, and other evidence of blocked blood vessels. When a blood vessel becomes inflamed and narrowed, blood supply to that area can become partially or completely blocked.
Vasculitis can be classified by the cause, the location, the type of vessel or the size of vessel. 1  Underlying cause. 2  Location of the affected vessels. 3  Type or size of the blood vessels that they predominantly affect.
