Re: SER1 Brake Master Cylinders

Hi Mark,

Eh….The conversion was relatively simple,
1 take the new cylinder, and take it apart.
2 drill the holes in the casing to a bigger size and then rethreaded 
them with the proper threads.
(I made a mistake with assuming that the treads used on the brake system 
were metric size. They ARE NOT!!!)
So you have to use English treads, (witch were very expensive to buy 
over here.)
4 Put back guts of the master cylinder after you’ve rethreaded the two 
holes. You have to replace the push rod from the new master cylinder 
with the one from the old.
The one from the new one is to long.
5 You also have to drill 2 new holes in the chassis-plate where the 
master cylinder is mounted.
Remember to use special brake “paste” when you put the brake parts togther.


But…….I’ve replaced the master and the brake cylinders and the rubber 
hoses. I also had to replace some of the pipes, witch were damaged by 
dismantling the old master cylinder.
Its all put together on my car, but I have a little nagging problem with 
air in my brake system. Until now I did try to bleed the brakes once, 
but I was not able to get rid of all the air. I do not have any fluids 
leaking.
I have tried leaving the car with its nose up, as suggested by some of 
the mail group readers, but until now I’ve no success.

If you do not have the proper tools, I can make a converted cylinder for 
you, if you wish so.

Greetings from Holland,

Coen
