You wanting to know the spanner size? i don't understand your question, cant be specific but my halfords brake line spanners are 8-10 and 9-11 mm so its one of them

The spanner size for the wheel cylinder side is 11mm. I just replaced a cylinder on Wednesday. It did not want to come off. Penetrating spray, heat and mole grips got the brake line and bolts off.

Sorry , for not being more specifc. I'm looking for thread size and pitch,so I can find right replacement before I remove rusty one on the car.

If it is a for a drum brake, the thread size on the cylinder is M12.0x1.0

everything else is M10x1.0

if your car is ABS model, the thread size might be M10x1.0.

The reason I know this, is because I made up some brake lines in M10 and the union was to small for the cylinder

[Alexa]

Is this OK

[MartinObviously]

Yes that looks correct

[Alexa]

One of the rear break lines are dry.I checked and disconnected pipe from the master break cylinder and there is no Oli leek.Is this mean that master break should be replaced since it's not pumping oil on that line?
Others are fine and breaking normally.

Do you have the rear brake bias valve on the rear axle? It is more likely to be that than the master cylinder.

Thanks, problem solved.
