    Brake Fluid - Where does it go? Ford Focus

    i'm assuiming its brake fluid issues, my Focus handbrake/brake warning light comes on when i go round right had bend/roundabouts so i'm assuming that the fluid is moving away from the sensor (i assume the sensor is on the drivers side of the brake fluid pot) this has been a sudden thing, it doesnt come on under braking so im 99% sure the brakes are fine,

    so apart from a leak whare does it go? can it avaporate? i dont have ABS i dont drive the car hard so its not boiling

    oh and what fluid should i use? i'm not sure what is standard in Focus'

    Could it be one of the brake pad sensors causing it to come on?

    When your pads wear down, the pistons are pushed out more so the fluid level in the reservoir drops.

    It'll have gone down just enough so that cornering makes the light some on.

    Pad wear indicators are usually an orange symbol. What Rusty says is correct. You shouldn't be topping up brake fluid. If the level is impacted it's trying to tell you something!

    i've just had a quick look i have pleanty of meat on the outside pad on both the fronts, both are approx the same amount but i cant see the inside pads.

    will the pads wear the same on each side IE on the driver side will the outside pad wear the same as the inside pad?

    the pads can wear differently, so could be work checking but I doubt you have pad sensors

    if your fluid is low, top it up before it runs dry. Use normal dot 4. If the light still comes up then investigate

    cheers dan, i'll get some dot 4 on the way home.

    i'll also whip the wheels off this weekend and check the inside pads for the fronts.

    is it worth checking the shoes as well?

    Check the switch on the handbrake lever inside the car. If the lever pivot is starting to work loose, the handbrake can "fall off" the switch, making the light come on on the dash.

    If it has shoes the cylinder(s) could be leaking inside the drum.

    Check to see if it's wet under the gearbox, you may have a leaking clutch slave cylinder...
