Another point on brake conversions, if the car has large (14" etc.) body mounted cylinder, I do not believe an AB or ABD valve will not flow enough air. Modification to any brake system is really a re-engineering process and is seldom necessary. I often say to volunteers at my group "don't we have other things to do instead of re-engineering something that already works?". Pittsburgh Air Brake can explain these details if you have questions. Besides, K brake valves are not that hard to work with, unlike the very heavy UC valves.<br><br>
