Monster Posted March 30, 2016 Share Posted March 30, 2016 You RHD guys should fit the Disco double diaphragm servo if in need of a replacement. It should provide a good 25% increase in boost over the defender one. Properly working Defender brakes should be very good. Red 90. Can you tell me more about the Disco double diaphragm upgrade? I have a 300tdi disco that I could 'borrow' the servo from. Will the 110 master cylinder bolt straight on or will I need to keep the Disco M/C?

Ex Member Posted March 30, 2016 Share Posted March 30, 2016 It should just swap over as long as they are both the same era (same bolt pattern). Quote Link to comment Share on other sites More sharing options...
mickeyw Posted March 31, 2016 Share Posted March 31, 2016 I have an idea Miketomcat has used the Disco servo. I seem to recall mention of some modifications being required to something to get the Disco servo and Defender MC to link up. Mike????

Monster Posted April 2, 2016 Share Posted April 2, 2016 Found this on the net regarding discovery servo and defender mc on to a series. http://www.nickslandrover.co.uk/braking-sorted/ I have checked and the servo/mc on the disco 300tdi that i plan to use. It has two pipe outputs so i may not need to use the defender mc after all? I was also thinking of replacing the 'safety' valve on my early 110 setup with the discovery balance valve. Be interested what others have tried. Quote Link to comment Share on other sites More sharing options...
deep Posted April 3, 2016 Share Posted April 3, 2016 I have scrapped at least fifteen 200/300tdi defenders. Every single one of them without exception with the later type servo has had a faulty servo with hairline crack in the usual place. Sometimes these will hold a vacuum but as soon as the pedal is pressed the crack opens up at the vacuum is lost. Interesting. I have a 1987 ex-military 110 diesel and it had exactly those symptoms. When I replaced the servo, I looked into the old one and was amazed at the size of the broken plastic bits inside! The new servo is great. In fact, the whole braking system (disc/drums, like the original poster) is powerful and progressive and very even. Just good maintenance really.
