hello,

im going to be fitting a hydraulic handbrake to my sierra in the coming weeks, just been browsing and all the ones i can find say they come with certain master cylinders with different bore sizes? heres the list they give me...0.625, ,0.700 & 0.750

now i have no idea what the differences are or which one is best, can someone help me?

thanks!

 

This applies if you change master cylinders for the same brakes,

the bigger the cylinder, you will have less travel on the lever, but you use more force for the same total braking effect.

I use a 0.625 one, and the travel is not all that much, but it is very nice to use with little force!!

 

so if i had a 0.750 it would have less travel than a 0.625 but it would be harder to pull? or am i getting the wrong end of the stick? lol

 

yep, i'd let you try mine out, but there might be a small distance issue!!

hahahaha!

 

My Driftworks one uses a .625, as do a lot of people, if that helps.
