My brake light is stuck on most of the time, though I'm pretty sure that the brake is fully disengaged and not dragging. Can anyone tell me where the switch is for that so I can remedy this? It's annoying.

 

98 Impreza.

 

Thanks!

Check the level of fluid in the

master cylinder.

 

As the pads ware, the fluid level drops because the pistons

move out.

 

The brake light will come on to warn you

of worn pads, it can come and go if the level is marginal.

 

If it's low and you simply fill it.

When you do change pads it will over flow

and take some paint with it.

 

Also the smal float in the MC can stick.

Wiggle it with a small screw driver to free it.

 

If it is the Ebrake switch,

I believe it's under your center console.

Pushing the handle down should cause it to go off.

 

Hope this helps.

It was just inspected a few months ago and the pads were nearly new then, so I don't think that they've worn down that much. I'll check the fluid level again just to be sure.

Also check the altenator output just for the hell of it. But odds are the diaphram in the cap needs to be pushed back in.

"But odds are the diaphram in the cap needs to be pushed back in".

 

I don't know where Nipper is going with this but

some people may read it as the switch is located under

said diaphram.

(The one under the master cyl cap)

 

Although some older Subies did have the switch in the cap,

in my Legacys the switch is located in the bottom of

the master cyl.

It is a magnetic reed switch.

 

A small magnet located in a white

float turns the switch on when the fluid is low.

The magnet pulls the reed switch closed.

 

I have had this float stick in it's well.

Turns out the fluid was low, which explains why sometimes the switch would turn off going down hill.

 

Kinda irks me because I had a shop repair a line and bleed the brakes when they did the alignment. Gonna have to have them do it again. It's too cold to work in my driveway now.

glad it's fixed

thanks for the update

 

 

BTW no need to re-bleed the brakes

unless the pedal is "spongey"

or pumps up.

 

The light goes on way before the cyl is out of fluid.
