---- and to include the brake master cylinder, now we can get seals for the master cylinder from Simon. Keep a look out. I will announce it here too.
Roy
I overhauled the master cylinder this fall, and I made a post with photos. http://www.matrasport.dk/forum/index.php/topic,2023.0.html A particularly valuable piece of info is, that there is a perpendicular hole in the cotter pins, which allows you to pull out the pins with relative ease. I hope you include that in the booklet. Also place close attention to which way the seals are mounted on the pistons before removing them (take a picture as reminder) With a little care, you do not lose very much brake fluid in the lines from the master cylinder (bend them slightly upward before unscrewing) Then after reassembly and filling the reservoir, you can take off a wheel from each brake circuit and press in the caliper piston. That pushes enough fluid back into the reservoir, to clear out any bubbles in the top of the lines. Result, rock hard brake pedal. That said, honing the master cylinder and replacing the seals is a relative easy afternoon job.

Quite right and just what I do too. Roy

Very nice tutorial Roy. The old one helped me a lot in my brake overhaul, and now it is even more complete describing the piston settings and the master cylinder. I have only one remark. In the tutorial is stated that you can use the baggy caliper, and that is true, but not in all cases it is a direct fit. Is there more then one type of baggy caliper? A fellow member did try to use one in a Murena but the handbrake lever is not equal, it has a different angle. He had to use the lever from the murena. See the pic and notice the different angle. The rusted one is ofcourse from the baggy. pic Urbain.

You are quite correct, and thanks for reminding me. I am so used to overhauling these things now, I can easily forget things like this even though I know them. In fact you can use the calipers from the rear of an Alpine A110S 1600 as long as again you change the hand brake levers... I will update the book to include that, thanks again Oetker. Oh, and to answer another question - it is locked against copying and printing I'm afraid. It is meant for personal use, but I found even the Lotus club were displaying the old one on their website without asking my permission (yes that's another car that also uses this caliper) so I have locked it this time. Sorry. Roy
