Depends if its drum or oil-cooled disc brakes. What does it say on the side of the bonnet, does it have odb or oil-cooled disc brake labels?

For example, if it has oil-cooled disc brakes and the person who serviced it put gear oil in the front axle you won't have any slave cylinder piston seals left as the gear oil reacts with them. You also would lose all your fluid though...more info required really.
