Replacing brake master cylinder today

[growler2058]

Howdy trollers!
Starter motor yesterday and master cylinder today. Somewhere in the past i read to pre bleed the master cylinder as it makes bleeding the rest of the system a lot easier. So can anyone tell me how to do this cheers.

[silly one]

hey mate realy easy b4 you put it in the car put it in ur vice or get some one to hold it and all you do is fill the resouvor and get a phillips screw driver up where rod goes in the back and i cnt memba how many outlets there are but try pushing the screw driver in and DO NOT PUSH IT ALL THE WAY TO THE END AS IT CAN INVERT THE SEALS AND STUFF IT but any way as ur leting the screw driver cum back block off 1st 1 or 2 with fingers try to block off all out lets but if you cant dnt realy matter but continue procedure until u get fluid out of all of them just remember as ur pushing screw driver in fingers off when taking screw driver back fingers on its realy that easy

Vacuum bleeder mine connects to a compressor.
But you can get manual ones.

The nipple snapped off when i was trying to undo it :-(

What if you undo the line and bleed it through that on second thought unless you have a good quality brake line spanner don't even go there lol.
