I was able to purchase a new seal for this forklift and was able to get rebuilt brake slave cylinders. Unfortunately I don't recall the name of the company I purchased the parts from. I used old military parts manuals to find part numbers and then searched the internet on those. The supplier was in the USA and the parts were not that expensive. Sorry I can't help more. I wish I recalled the name of the supplier.
