Yes, changing the master cylinder can affect the way you bleed the brakes. When a new master cylinder is installed, it may require a different bleeding procedure due to potential air trapped within the unit itself. It's often recommended to bleed the master cylinder before connecting it to the brake lines to ensure efficient brake fluid flow and eliminate air. After that, you can proceed to bleed the brakes at each wheel as usual.
How do you bleed master
There is still no fluid pressure. Make sure that the master cylinder was bled as well as the wheel cylinders. New master cylinders can be tough to bleed all of the air out. The new master could be defective.
If you didn't bench bleed the master you need to do that before you install the master.
You need to bleed the entire brake system. Bleed in this sequence, RR, LR, RF, LF. If you do not know how to do this, do a search online for "bleeding brakes" THE REAR WHEEL CYLINDERS MAY BE LEAKING SHOULD ALWAYS CHANGE WHEN DOING BRAKES AND BLEED REAR BRAKES

No.
On any brakes I have ever done you use the bleed valves on the back of the cylinders. open when some one gentlysteps on the brake for you.
did you replace the master cylinder if so it has to be bleed frist
You bleed the rear brakes the same way you bleed the front brakes. If you can't get brake fluid to come out the rear bleeders you may have a faulty master cylinder or the master was allowed to empty out the reservoir that feeds the rear and now it is air bound. Removing the master cylinder and bench bleeding the master may be what you need to do and don't let the reservoir go dry!
