YukonJack Posted June 9, 2017 Report Share Posted June 9, 2017 Ok, I've seen the posts for installing a later master cylinder behind the gutted out stock master cylinder. My question is regarding push rod travel. Once the push rod makes contact with the piston of the master cylinder, how far does it need to move to fully operate the master? Sounds logical to me, or am I over thinking this? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted June 9, 2017 Report Share Posted June 9, 2017 (edited) if your system is bled and free of air...displacement begins immediately.....are you asking what is the stroke and CC Edited June 9, 2017 by Plymouthy Adams Quote Link to comment Share on other sites More sharing options...
YukonJack Posted June 9, 2017 Author Report Share Posted June 9, 2017 So it makes no difference if the piston is pushed in 1/2" an inch or 2"? Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted June 9, 2017 Report Share Posted June 9, 2017 displacement begins with the first movement of the piston, brake application will be on the condition of the brakes and the space the shoes need to travel to contact the drum and then add in the speed and mass you are trying to reign in which is now the force of the contact........still not sure of your question here....

The piston in the master cylinder beings moving the instant you put your foot on the brake pedal. The length of the push rod is irrelevant.
