For what you would spend on a hone and rebuild kits you wouldtn't be too far off from the price of new wheel cylinders. In fact most times the complete cylinder is less than the rebuild kit. We never rebuild wheel cylinders or calipers at the shop for this reason. there is also less chance of failure due to pitting/out of round conditions. Find a parts house that carries Wagner brake parts, they are a division of Federal-Mogul and are top quality parts.
