Brakes binding, hard pedal on Zetor Forterra 125

Hi, anyone have any ideas as to why my brakes are binding and hard pedal. There is also a warning light, looks like a brake warning switch flashing intermittently.

Many thanks

Not to sure check to see is the brake fluid in the reservoir I take it,s a side shaft model after that the external disk one of the pads are wired up to the dash not to sure what light it brings on in the dash best read the operators manual The rear brakes they can stick on so when running put hand on top of rear axle to see which side is sticking usually i just put a chain hoist on the linkage a pull back to where the linkage should be when the bake pedal is not depressed and coated it with loads of penetrating oil as it is very common problem as rust builds up on the linkage and keeps the rear brakes on

Is this 125 still a classic dry disk, or the newer wet lamella brake system ? If the latter, you're looking at either a plugged up brake line or a piece of worn brake lining came off and jams your brakes..

If its the classic dry disk, you can try WD40 on the linkage but mostly its on the inside, the ball that rides up that curve to expand the disks against each other...

Forterra have as to my knowledge never had dry disc brakes. and i have never heard of lining problems, i would look at adjusting the Space of the linkage from brake pedal to master cylinder making shure fluid can Return freely to reservoir, Because of the hard pedal i suspect this cause, i now own my 4th forterra and never had a brake problem. on the super 7341 we had same problem like described hard high pedal and sticking brakes, that was because the adjustment of linkage from pedal to master was not right, causing fluid to not Return to reservoir.
