Well i am very glad i found this forum and hopefully you guys can help me. My girlfriend has a 1995 honda accord v6 runs great but the past few months when she stops she begins to lose brake pressure. Usually you can stop the car and hold the brakes at a set place and the car will stay stopped hers almost lose pressure and start to move again. Also her brake light and abs light came on. Any ideas? Thanks for all the help

 

Check that her brake fluid is filled to the appropriate level. Also look for signs of brake fluid leaking around the master cylinder.

 

If the brake pedal sinks slowly & smoothly to the floor while holding (like at a red light); thats pretty CLASSIC for a bad master cylinder. It leaks internally, back to the reservoir, so it wont necessarily leak OUT.

But still... look for externalleaks too.
