"w203 rare brake Fluid leak"

I have an c240 2002 and i notice that it has been leaking brake fluid I took it to the mechanic and they told me that the brake fluid reservoir was leaking..

I just want to make sure because it doesn't make any sense the canister seems dry ..

The leak is around the brake canister area but is really hard to tell where it is.. what could it be, what should i replace? i have to refill this every 3 days because the lights goes on..

please guys what do you think this is ?


thanks

Clean up the area. Then turn on the car. Have someone else hit the brakes while you look, with an angled mirror all around it, and see if you can find where its leaking.

Thanks for your response.. I would do this tomorrow

Today i checked for leaks spot but the brake fluid canister seems dry " i even put tissue paper just to see if the leak was in the canister and it is dry".

What i notice that in the bottom i see brake fluid so the leak is between canister area but what should it be ?

What parts are below the brake reservoir ?

I would find the leak pronto because the fluid is a very good paint remover. The other leak locations can be around the master cylinder. Sometimes the seal fails on the pedal input to the cylinder and the fluid leaks into the passenger compartment and hides under the carpet.

I did this today with a frined, but i don't the DAMN LEAK ,what i notice is that the reservoir in the left "stick" bottom left area was kind of WET so definitely the leak is in the top not on the caliper or brake lines...

The car stops perfect no issue at all, NONE master cylinder symptom like spongy pedal or stuff like that..


If you have something to suggest please let me know because this is driving me nuts..

Translate please or post a picture. If it's leaking where the reservoir plugs into the master cylinder then replace the resevoir + rubber seals....can't be that much $. You need to bleed the system if you do this.

thanks for your response..

I'm taking the car to the Indy this week to get a full diagnostic to make sure of what to buy..

but now that you say rubber seals i think this should be the problem.. because the leak is around that area I don't see it but i feel that oily or wet area.


let's see what happens thanks guys for your response !!!

If some one has another opinion let me know This could help a lot of people!!
