steering wheel off, heater switch wires off, top of the hand throttle off and tacho drive off, there should be 2 crosss head bolts either side of the dash and you can slip her off just about

little bit of wet and dry just to polish the bore, if they are green seals in there already then its had a set before so they might not last an amazing amount of time, dont forget its lhm for the fluid

there is nothing wrong with replacing seals i have done it many many times, from new the seals were black, replacements are green, if the bores look ok and the seals feel nice and snug then go with the reseal

When you remove the cylinder remember to wash all components clean as dirt in the old fluid can roughen the bore and the plunger, as said, determine the amount of wear and polish the inside of the bore and the plunger with very fine steel wool, DO NOT use wet and dry paper or emery cloth. If these clean ok to a shiny surface then you should have no issues with fluid leakage with new seals fitted. If the components still remain after cleaning with a dull dark colouration, renew the whole unit. It is also advisable to, when you dismantle all the plunger components, to lay them out in the exact way and position they come off as it is very easy to install parts of the new seal kit the wrong way round. In the kit you will also find a sachet of grease, only use a very thin smear of this to lubricate the bore when you push the plunger back in otherwise the grease will block it up and the fluid will not pass and operate the cylinder. Again, as said only use LHM fluid (in both the clutch and brake reservoirs), this fluid can be obtained cheapest from any garage, motor repair shop that deals with Peugeot and Citroen cars as these use the same LHM fluid, normally should come in 1 litre container.
