Break Question
 

OK i got a 1990 acura integra with abs, my car has a master cylider and a abs cylider. What my problem is the break seems to drop to the floor every once in a while, and also all the fluid from the master cylinder goes into a abs cylider over a period of a time. I was told to check for any leaks of break lines or anything like that and i did all the lines are mint and go inside the car so i didnt notice any leaks. Could it be the master cylinder? Any help would be great.. Thank you

Does the brake pedal drop to the floor when you're stopped? Like at a light or stop sign?

If so, it's your master cylinder.

yes it does but only once in a blue moon..

a dropping brake pedal can be cuased by either an internal leak within the master cylinder, or a leaking wheel cylinder

hondas have problems with their primary seal leaking in their MC.

Looks like you'll need to purchase a new one. (id def. get it checked out though first)

yeah, warm weather or heat from driving makes the master cyl act up. change it before summertime hits. mine was the same way, it was intermittent.

well i changed the master cylinder and the breaks seem to be in order now, thanks to everyone that helped..
