l have anti lock brakes and when snow gets into the brakes, they lock up on me and l slide, with the brakes making a thinping noise.l just had new brakes put on the car May 1, 2007.l checked thr brake fluid, but it is empty.

add fluid and have your brakes checked

l would have a mechanic check the master cylinder and the brake lines, however, l am betting the master cylinder is bad. Lines usually dont wear out unless the get pinched or cut--they are steel. How much it costs depends on who does the repairs, dealers are outrageous while independent garages will be a little cheaper.
