Hello! I have a passenger coach which uses an air brake system.
Recently, the air compressor failed and the lubricating oil (engine oil) leaked to the compression chamber. The large amount of oil finally gone through the air dryer, via brake hoses reaching various valves.
Is there any negative effect of the oil on the brake hoses / valves? Is it worth to replace the valves / brake hoses?
