most cars take dot4, its not hard to do but im sure a bleed nipple will break somewhere along the line..
1st thing, jack the car up and remove the wheels, but make sure the rears got axle stands under the rear beem or the bias valve closes.
2nd get something to suck all the brake fluid you can out the fluid pot, then top up with fresh dot 4.. get a mate to ready himself in the car with the brake pedal.
3rd get a small clear hose thats fed into a bottle with a drop of fluid in the bottom, fit to brake nipple, crack off the nipple, get mate to pump pedal but NOT to the floor.. this can get the master cylinder stuck causing more problems. watch as the fluid come out, wait till it runs a clear gold and bubble free, and when you want to lock off the nipple get your mate to press the pedal down. dont lock the nipple on the upward movement, only the down. do each other nipple the same making sure to top up the fluid pot.. i go round each nipple twice..
check level and pedal feel, should be solid, maybe run the engine to get the servo to kick in.. job done
you can get an eazy-bleed for £20 that fits to the brake fluid pot, it tops it up and forces the fluid through the lines while you crack the nipples off.. its meant to make it a 1 man job but i still find it takes 2 people, just saves messing with pedal pumping..
if i were you i wouldnt try it, its not hard but im yet to crack off a rear caliper nipple on a clio that doesnt break.. also if you start going wrong your car is not road fit and you'll need to call someone out..
you dont f**k with brakes, you could kill someone..
get someone who knows what there doing to come teach you
