Thanks in advance for all of your contributions.
Recently our 2004 Yale lift truck exhibited issues side shifting the forks under load. Shifts fine to the side with empty forks, but once we are carrying a load it wont shift sideways.
Also, seemingly unrelated the brake pedal requires more force to stop the truck...
(1) Could the brake and sideshift issues be related?
(2) There is no dipstick or sight glass for hydraulic fluid...how do I know if there is too much or not enough hydraulic fluid?

My guess ids that the hydraulic pressure is too low. You have to check the pressure with a gauge and adjust it at the control valve if it is too low.
I have only seen 1 pair of brake shoes wear out in my 40 years in the business. Most likely the wheel seals are leaking and have allowed the brake shoes to become oil soaked. I suggest replacing the weals, shoes and wheel cylinders.
There is no dipstick. The oil cap is a galvanized NPT pipe cap (don't think it's OEM), looks like 2". I'll buy an OEM oil cap.
The brake shoes were already not happy. We've always had to push harder on our Yale to get it to stop. Maybe we just lost the last bit of shoe now it's completely metal on metal. I'd probably better get new shoes before we have to replace the entire drums.
What's the easiest way to check shoes for wear? Please tell me I don't have to remove the wheel and drum/hub cover...those things never come off easy for me.
The brake and side shifter problems should not be related. The dip stick probably is under the cap that you unscrew to fill the oil tank. The side shifter may need greasing or the seal in the hydraulic cylinder is leaking by and not allowing the pressure to make enough force to move it. The brake shoes may be getting grimy and not making good friction anymore.
