Brakes don't work.

[Wandering Soul]

I have a Swiss 710K. After setting a few months, the R front brake has leaked all the fluid from the L fluid reservoir. I am rebuilding the brake reservoirs. The problem is, the R fluid reservoir is full, but the pedal goes to the floor and pumping the pedal doesn't help. Is this a master cylinder problem? Thanks for your help.

I am not aware of 710's having 2 brake reservoirs, but I only have a 710M. There are 3 in my truck, brakes, clutch and lockers.

If you have a leak in one, I would replace the reservoir. Easy to do and you can get the newer version. Sounds like air in the line (at a minimum) and they need to be bled. I always like the power bleeders for this, easy to do with 1 person and if you leave it attached for a few minutes, it will tell you if there is a leak in the system. If/when you get your pedal back, I would look to adjust the drums as well.

Brakes on a Pinzgauer are no joke, be careful.

The reservoir is divided into two compartments.
