l have a 1991 Suzuki Swift, 4 door, hatch. it has manual transmission. When driving, it sometimes drips a dark coloured fluid onto my right foot (mainly), but also sometimes onto my left foot.
this is really starting to screw up the interior of the car and is really smelly. l have a feeling the it could be brake fluid or clutch fluid, but in saying that, l really have no clue about cars so im just guessing.
any help would be awesome!

The clutch & brake pedals push into the slave cylinders (if u have hydrolic cylinders ) if u take a torch & peep under the dashboard above the clutch & brake pedals u would see where the leaks are.
You could buy slave cylinder kits (rubbers ) to replace the old ones, but it is not too expensive so rather buy new clutch & a brake slave cylinders . New seals do not last too long because the sleeves r normally worn as well.If u r mechanically minded it is not too difficult to do the job yourself, just take note how everything comes out, so u know how to replace the cylinders.
