Hi,

I have an 93 Honda Accord Ex, it has ABS. Since I bought it it has many leaking problems I have fix them all accept for the problem on the brakes system.

The Fluid keep transfering from the Master Cylinder to the ABS Modulator, I have change the master cylinder out and even change out the Modulator thinking that would solve my problem but it still doing it.

Now i'm stuck not sure what's the problem I gues the only thing left is the pump acculator that I haven't touch.

There is no code no lights what so ever on the car.
Can anybody help or ever run into this problem? I have been searching the net for days and haven't found the answer.

Hi RomeoOG,

The modulator is bad and leaking internally. If you had replaced with used parts, it would not be surprising that it reoccurred.

Thank you for the answer, You know there is 2 little hole that when I press on the brake before I saw fluid coming out on the hole in the front if that means anything the hole in the back doesn't leak fluid.

So is that mean the Modulator is bad?

The 2 holes should be sealed with rubber caps. If any is missing, internal leakages has occurred causing the stopper to be expelled.

It means the modulator is bad.

The 2 rubber seal is missing when I got it. What I did was put something on it and seal it with JB Qwik and it still doing the same thing before which is transfering fluid from the master Cylinder.

So I gues buy another one?

You got a bad modulator and should get the seller to replace it for you.

I bought it from a Junk Yard so I don't think they can help much.

Anyways I just place an order on Ebay it comes with a complete pump accumulator & also the modulator, but I notice that there's no rubber seal.

Do I need to seal it before install it? Does it matter if it has a seal or not?

If it is a used unit, no rubber seals means that the accumulator is bad.

Do not install, get a replacement part first.

The junk yard should exchange the part for you.
