Land Rover Series 2/2A 109" CB Brake Master Cylinder This Master Cylinder was sleeved in Stainless by Past Parts in 2014 and was in use in my 109" until 3 years ago when I converted to a Servo assisted brake system. You can see from the pictures that it is still in excellent condition with no deterioration to the internal cylinder, it is ready to fit and use but you might prefer to replace the seals for piece of mind.
