Default BRAKE light ON

I've now got a BRAKE light that usually comes on in the morning. Usually disappears when I use my car during the day. I've got a manual. I just spoke to a coworker who's got an automatic and she's been having the same problem during the last week? How weird? She's got no mods, so that makes me feel better.

Brake fluid is good, so I dunno.

Any Ideas

Try removing the top of the Brake Fluid resevoir. Inside the cap there is a rubber diaphram, make sure the diaphram is collapsed inside the cap. If this is distended it can trigger the "Brake" light for low fluid.

If this is OK, make sure the handbrake is fully released

Also make sure that the fluid level is well above the min line. If it's boderline, it can trip the warning light when the fluid is cold. That would explain why it goes away, with use. I had mine drive me nuts, for about a week.

Default float could be stuck

check that the float inside the resevoir is moving freely. Mine got stuck to the inside of the resevoir and wouldn't float up. When the float is up, the light is off, when fluid is low the float comes down and triggers the light. Good luck...

Default Antilock?

Dunno about the 97's but there seem to be a LOT of things that will turn on the brake warning light in my 00. One of them is the anti-lock system. It has a hydraulic pump and until the pressure is high enough the brake light is on - so is the antilock light. My last car was a Peugeot and it had antilocks too; the only way I knew that had enough pressure built up was by the brake warning light, and in winter that car used to take a few extra seconds to build pressure. It could be that on a Subie that's a few years old the same thing is happening.

Good luck,

I had same problem with my 94 Legacy Turbo...... in the mornings only the brake light would come on and won't go off even after handbrake is released... once the car is warmed up.. say around 15 minutes of driving. If i shut off the car and start it again.. it will go off. If i just keep driving it will stay on the whole time. My brake fluids were fine but pads are low....... and it doesn't seem to happen in warmer days.... Some have suggested that my handbrake cable has to be relubed and there was moisture in it, so it won't fully release, however i don't think that was the case for mine becoz even if i left my handbrake off for the whole nite, the brake light came back on once i reversed out of my driveway and hit the brakes.

after brake flush and new pads, it still happend on the next morning. but then after that it never happend again..! weird, but if it really worries u, brake flush will probalby work. worked for me.
