The One And Only Brake Fluid For Citroën From February 1982 Is Called LHM+ And We Have It.
All today’s cars use DOT 3, DOT 4 and DOT 5.1 as brake fluid. Only Citroën uses LHM+, green hydraulic oil.
But be careful! The early 2CV’s need normal brake fluid; the later models LHM+. You can see very easily the brake fluid your car needs. If the car has front drum brakes (until February 1982) than it needs normal brake fluid. If you find disc brakes (from February 1982 onwards) than LHM is required.
To tell LHM components apart from normal brake fluid components all LHM parts have a green mark. Master and wheel brake cylinders are painted green or have at least a green spot. Even the small seals for the brake lines have a green spot. The brake fluid is green as well. When the car was new there was a sticker on the brake fluid reservoir. This sticker told in multiple languages that only LHM is good for this brake system.
You can find similar information on the cap of the reservoir. Quite often the sticker has gone and the cap is covered with dirt… but even if everything was clean, nobody in a workshop will read this! Not because the mechanic can’t read… its just that very few people realize that a 2CV needs a different brake fluid than every other car.
If you use normal brake fluid in a disc brake system you destroy the entire system. Both fluids are very aggressive against the rubber seals of the other system. If you use normal brake fluid in a LHM system all rubber seals will disintegrate. So the complete brake system will fail sooner or later!
Experience shows only a few mechanics know about this fact. If somebody tops up with a normal brake fluid and the LHM brake system is “mortally ill”! The first problem will occur with the rear brakes. The rubber seals in the wheel brake cylinder start to disintegrate and seize up the pistons.
If you don’t hit the brakes very hard the rear brakes don’t work at all. This enables the brake shoes to rust in. On the front brakes you will find out about this problem when you try to replace the brake pads. The pistons can’t be pushed back into the calipers.
Finally the master brake cylinder seizes up. This means you push the pedal as per usual… but when you release the pedal the brake pedal won’t come back out. It takes a few seconds before you have pressure again.
If you now open the cap of the reservoir you might find a black slime on the bottom of the reservoir and on the screen. This slime is the disintegrated rubber. A change of brake fluid is already too late. The seals are destroyed.
If you let the replaced brake fluid settle down for a while you can clearly see the two fluids separated. In the middle between the fluids the black stuff is in fact rubber particles. If this is the case the entire brake system has to be replaced. If you try to flush the system with fresh LHM you will find that there is still some old DOT fluid in the calipers and the rear brake cylinders. This is enough to start the destruction all over again. If you give your car to a mechanic let him know about these facts and make sure that he understands. Your life may depend on this!
