We have had our master cylinder replaced on our scooby doo bled everything, all back together no leaks etc. Will say master cylinder is a used one and come with car when bought it...just to state the cylinder wasnt bought by us so we dont have receipt for it..But when driven one minute brake pedal feels firm and only needs little pressure then often it goes more than half way before the car stops, bled 3 times and still the same. Any ideas???? Need advice ftom scooby owners to if this is normal for this car or not? We own a uk 2000 turbo v reg
