I haven't changed anything on the car at all. It is a stock 92 Civic LX 5 speed. Everything has been fine until the last few weeks. It starts after a few minutes on the highway, I feel a light vibration from the front end, and pressing the brake makes the vibration worse and felt through the brake pedal, steering wheel and basically the whole car. When coming to a stop, if I put it in neutral and coast the last few mph, I can feel the brakes dragging a little bit.

Letting the car sit for a few mins (like 5 mins) causes it to go away. No parts have been changed at all. A few months ago (about 3 months) the brake light came on when I was making a turn and the first thing I checked was the fluid and it was at the 'add' line. I added the correct fluid and nothing else happened. The car has been driven like 3000 miles since then without incident until now.

Any ideas? Most things I found when searching were related to part installs and not popping up like this..

 

when was the last time the brakes have been changed?? rotors maybe warped.

 

I'm leaning toward rotors or caliper issues but it's odd that it only does if after being on the highway and not any other times

 

possibly cause being on the highway allows them to actually heat up more than jus a normal 10 min drive in town? i would get it up in the air and just inspect the brakes. look at the pads. if they need replaced thats what i would go with. new brakes new rotors. or if the rotors are able to be turned at a local automotive store.
