What Type of Brake Fluid Should I Use In My Citroën 2CV?

What type of brake fluid should I use in my Citroën 2CV ?

This question recently was sent in and here is my answer:

  1. If you have a pre 1980s Citroën 2CV (that is a Citroën 2CV with four wheel drum brakes), then you want to use a good quality DOT 3 or DOT 4 brake fluid . My own personal choice is a DOT 4 product made by Castrol called Castrol LMA . (the LMA stands for low moisture absorbing ). As we all know, this is a good quality for brake fluid to have since it is by nature hygroscopic, or has a tendency to absorb moisture.
    Regardless, the other bit of info I can’t stress enough is to completely drain and flush out the system at least every 2 years in your Citroën 2CV . More problems and troubles with brakes seem to be caused by neglecting to do this fairly simple procedure, and moisture builds up in the system and corrosion occurs.
  2. OK, second answer to the question: If you have a Citroën 2CV that is later then this date or has disc brakes on the front to be more accurate, then you want to be using LHM fluid . Yes, the same green stuff that you put in the hydraulic suspension cars of the same period.
    Here again you want to practice my advice of changing the fluid at least every two years. Changing the fluid is such an inexpensive form of maintenance, next to rebuilding or changing out brake parts. The more I find, as these Citroëns get older and enter collector status, people have a tendency to use them less and less, and this is where periodic maintenance becomes even more important.

So take care of those Citroën 2CVs because they just don’t make them anymore!

What Do You Do if Your Citroën has a Contaminated Hydraulic System?

What do you do if your Citroen has a contaminated Hydraulic System?

I know that I have harped on this subject for several articles now, but it is more of a problem than you might think. I found when I worked on Citroens , the cars either caught fire and burned or were abandoned because the hydraulic system had become contaminated and the owner found out that it was going to be mighty expensive to repair the car.

Well, the shop manuals and the dealer bulletins would tell you More >

Do you Think Your Citroen Has Contaminated Hydraulic Fluid?

Do you think your Citroën has contaminated hydraulic fluid ?

My little video yesterday showed you a simple test to do if the LHM system has a little brake fluid in it. Now I will tell you some of the tell tale signs to look out for when the system might be contaminated.

This may seem silly for a system that is marked properly on the hydraulic reservoir for what type of fluid it should take. But, many of these cars More >
