brake troubles eclipse 97
 

Hi everybody , i bought last week an eclipse 97 .

Now the problem is he has no brakes , if i press the pedal 5 times he has pressure enough to brake and he holds that pressure , but when i release the pedal and push it back in the pedal goes straight to the floor again . i changed all the brakeflued and all the air is out of the system . anybody a suggestion what it could be ? The plan was to change everything but the parts are rare here in belgium :) thnx

losing fluid?
Otherwise brake booster issue.

No leaks , double checked . :) yeah maybe i have to change that . could there be anything else than the brake booster ? Thnx for you're reply

I'm pretty sure that if the booster had a problem, you would still have trouble stopping but it would be extremely DIFFICULT to press the pedal. If you press the pedal a few times with the car off, the pedal should become very stiff. If it is still super squishy with the car off, I have no idea what is going on. You may want to bleed the system again just to be sure there is no air.
Very slim chance that one of your brake lines is damaged and begins to swell with all of the fluid. I've never seen this, only heard of it happening.
Unfortunately, it may be that the master cylinder is leaking fluid past the piston. But I have no idea how to test this theory, so it may not be much help. A rebuild kit is never too expensive, but it's just a matter of getting your hands on one in your part of the world.
