I was replacing the disks and pads on Mr's Bigsurfers Vauxhall zafira last night. While doing the last wheel rushing to complete it before it got dark I forgot to open the bleed nipple before pushing the piston back. I guess I forced the brake fluid back into the master cylinder (where it overflowed). I now have a soft pedal that sinks pretty much to the floor the first time you push it but can be pumped to be fairly hard. Brakes are really rubbish only just able to stop the car. I have bleed and bleed the brakes really well, putting close to 2L of new brake fluid through the system but still no joy. I guess I have damaged something. I have read on the great tinterweb that I may have damaged the seals in the Master cylinder.
I have worked on cars for years and changed many sets of brakes on many different cars but this one has me stumped. If no body suggest anything I will have to pass it over to the garage.
