brakes zetor 4511

hello
i remake the brakes of a zetor 4511.can i modified the adjustement of the space between the brake shoes with the fragokov brake cylinder.
any help is welcome.

hydraulic brakes should be self adjusting.

Or do you mean the clearance between the brake pedal pushrod and the master cylinder?

my english is not very good but i meanfor adjust the brakes shoes
with the drum

The self-adjusting part works by pushing the piston through a split collar which can move a small distance in the cylinder housing to allow the brakes to engage. When assembling the brakes it is a good idea to move these collars in until you can only just get the drums on. Other than this there is no adjustment on the shoes
Hope this helps, Dave

thanks Dave
i have pushed the piston in the cylinder housing and yet the drum
get over.
