For example. The manual will tell you to put the piston in the bore and then slide a feelers guage in the bore to see how much "play" there is. I think on most of them wear is OK up to about .005 of an inch. (Be sure to look at the correct manual) After that there is not much left to do but put in your new kit which contains new rubber cups.
As Wrenchbender stated. Get you a cheap hone and hone it out smooth. You'd be surprised what some serious honing will do. Note, most folks agree that some small pits right in the CENTER of the cylinder is OK as the rubber cups never go in that far. Use good common sense and judgement and you will be fine. If they are worn out you can usually find new ones cheaper than having them sleeved unless you want to pay to have them done in something like stainless. | | |
