hi all, the warning light has been flickering on my 1984 range rover for the last couple of weeks.today ive taken a look at it and as the brake pads were getting low ive changed both front and rears. ive also emptied and refilled the fluid. the light is still flickering and the brakes feel even worse now! i bled the system with an ezibleed kit and appeared to get all the air out,any ideas what i may have done wrong or should i suspect servo or master cylinder?
