unclip the spring on the pedle, pop it off the clutch lever in the engine bay, and replace the cable following the same path try to get the nut/thing at the engine end in the same place as the old one then mease the travel to get an accurate travel (124-131 mm)
Easy as hell. Look where the cable passes through the bulkhead into the car. remembre where this hole is. now pull the "C clip" off the thread on the cable (if there is one) and pull the old cable out of the gearbox end (will come out cuse its broke) and pull the outercable out of the engin bay. stick your head under your dash and look at the top of the cluch peddle, pull the reast of the cable out of hear. then push your new cable through the hole in the bulkhead from the engin bay. now back under the dash put the cable end in the top of the cluch pedle through the little groove then pusn the rubber gromet into the hole. now push the outer cable into its "stop bracket" onthe gearbox and pull as much cable as you can, and you should be able to hook the end into the cluch release leaver. then just keep screwing the funny shape nut up and down the end of the cable till the cluch peddle sits at the same height as the brake peddle, then check that your biting point is at the corect height. ( make shure you can get Reaverse without it crunching). when you are happy with the adjustment push the "C clip" back on as close to the leaver as possable. shut bonet, job done.
now apreashiate how smooth the cluch feeles, with no squeeky noises! ( I know you have them, every Nova dose, Hek eaven my corsa dose.)
