bgambino Posted January 6, 2016 Share Posted January 6, 2016 My moms 07 forester....95k Seems that the frigid cold brings out all kinds of problems! All of a sudden she gets in car and brake lite is on She does not use the E brake so it should not be a switch that did not release Brake fluid is above the low mark....topped it off anyway---saw nothing leaking under /around any wheel (inside or out) Lifted and released Ebrake numerous times...no change Any ideas? thanks Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted January 6, 2016 Share Posted January 6, 2016 Not sure about later models but on the 90's soobs that could be a sign of a bad alternator. 1 Quote Link to comment Share on other sites More sharing options...
idosubaru Posted January 6, 2016 Share Posted January 6, 2016 it's just the brake light not the ABS light right? top it off and see if the light goes out after warming up, maybe cold is delaying the response of the sensor. 2 Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted January 6, 2016 Share Posted January 6, 2016 Not sure on newer Subarus, but on an Audi I owned, it had a wear sensor attached to the brake pad. When brake pad wore down, a metal clip with an electrical connector would rub against the rotor. When this electrical connection happened, a brake warning light would appear on the dash. Another thought is that the ebrake handle needs a cable adjustment. With handle down, a loose cable isn't turning off the electrical connection, so light stays on.

ocei77 Posted January 6, 2016 Share Posted January 6, 2016 After running a while does the light go out? If so, it's related to condensation in the brake booster hose. In this case remove hose and spray with brake cleaner. O. Quote Link to comment Share on other sites More sharing options...

Most newer cars have a brake fluid sensor, as the pad wears the piston extends and the fluid level in the master cylinder goes down and a warning light comes on.

johnceggleston Posted January 7, 2016 Share Posted January 7, 2016 add 2 ounces of brake fluid to the master cylinder and see if that fixes it. DO NOT add too much. next spring when she has her brake pads replaced the master cylinder could over flow during the process. 1 Quote Link to comment Share on other sites More sharing options...
