I just bought a 95 accord ex. The brakes a real spongy, they go all the way to the floor. I bled all four wheels and it seemed to fix it, but after about a half hour of driving, they turned spongy again. I did not see any leaks around the master cylinder or wheel cylinders, nor was the brake fluid low, I did not see or hear any noticible vacum leaks. What could be causing this?????????

 

The "master cylinder" is leaking internally. You will not see the brake fluid come out. This is a common condition, when the brake fluid is not changed regularly. Brake fluid absorbs moisture (in the air, or wherever). This moisture makes internal parts rust (rust tears up the seals). The brake fluid should be changed every 30,000 miles or 3 years (I think).

 

BLKFLSH is right on the money, just take care of that and you should be ready to go. I had the exact same problem on my 91 accord. good luck man

 

Master Cylinder is an easy replacement on that car. Good luck man.

 

Thanks everyone for all your help and a really quick response. I really appreciate it. I am on my way to get a new master cylinder!
