This is not a video that will show you have to remove a snapped of brake cylinder ventilation valve, it is an attempt to show others what you are up against if it happens to you, it will also show you why BMW will just replace the brake cylinder and charge you as at £150 an hour for servicing it just doesn’t warrant a BMW mechanic trying to remove a valve and also it my not be safe to do so if the brake cylinder has been put through a lot of stress to remove the ventilation valve.
I had taken my 08/58 E82 BMW 135i for a service and the BMW UK mechanic had said that the right rear ventilation valve on the brake cylinder felt like it was going to snap of so he could not bleed that brake.
The mechanic also pointed out that the three other ventilation valves were tight, I managed to replace three and the forth snapped of.
In hind sight being that they only cost £5.00 each I would recommend replacing the brake cylinder ventilation valves every other brake service or every four years if you are following condition based servicing
The alternative may just turn out costing £450.00 for a new brake cylinder.
In the video you will see that all was going well until the stud extractor snapped of.
My only hope now is to weld a nut to the remaining stud in the hope that the stud may undo with a spanner if not I will end up with an expensive door stop
