Leaking Brake Fluid from Drivers rear.
So after washing the car its looking nice and shiny we set out to go to the local pub for my brothers birthday ,when I go to brake my foot goes right to floor with very little resistance and not really breaking that much at all. Luckily there was nothing in front of me and was not going quickly either as coming up to traffic lights and able to slow under engine braking , managed to carefully get home and test the brakes a few times before putting in the garage and still nothing .Looked on the drive and there was what I assume was brake fluid there and looking under the car then it seemed to be dripping from the calliper somewhere.
Does this sound like a simple job to repair ? I have a local garage coming to collect it and have a look at it tomorrow as I am not brave enough to drive to them and was hoping it may just be that the brake pipe has just unscrewed from the calliper but as I have no idea of the witch craft of the brakes I am not sure .
Thanks for any help .
