Hyster S80XL:
No brakes

hello
We have hyster S80XL
Serial D004D03654U
So when we apply brakes there is nothing almost till we get to half way pedal travel, then it just locks the brakes.
If we carry 2Tons, and press brakes we cannot stop. Just does not stop. Brake pedal goes to floor.
I check brake fluid reservoir, it was low and probably 20yr old fluid. I drained and got air out of system. I bled master , then right and left front wheels. Still does same thing.
Any ideas??

I seem to recall an issue with worn front axle mountings to brake back plates on the Hyster XL series that caused exactly this issue with brakes snatching and all or nothing brakes. Might just be worth checking the front axle mountings for movement.

Service life of a forklift is proportional to how well it is maintained.
I believe the truck was manufactured in 1997. Since the lift is 23 years old, I would suspect the brakes, brake hardware, wheel cylinders, master cylinder and all brake lines need to be replaced. Do not forget to replace all seals on the drum and axle. Before replacing anything, need to check your brake shoe adjustment. With the wheels off the ground and parking brake released, you should hear the brake shoe lightly dragging as you turn the wheel. If you know the brakes still have some material left, need to verify the wheel cylinders are not leaking and replace the master cylinder. Do not use old parts as they can fail anytime. If you have never worked on brakes, best to get a professional.

The hard to do we do right away. The impossible just takes a little longer.
