Was on the way home and my brake warning light came on... Pressed he pedal (on the motorway!) all seemed fine. Then on the off ramp going down hill, i braked and my pedal was soooo soft, didnt really slow me down so i pumped it and it had a greater effect. So i cruised home and all is safe. Any ideas what this could be guys? Ive done a little searching on google and it seems to throw up a brake leak... As i say my brake warning light is constantly on now when i turn the key.
