In September I purchased a FJF-040 (unknowingly at the time because the data plate was long gone) and through researching Baker forklifts came across this forum. It has been super helpful in tracking down the parts to replace the brake components.

I bought it knowing the brakes needed to be fixed, but this was before finding out the exact model I was dealing with. Replaced the master cylinder as that had an obvious leak, and tested out the wheel cylinders, which neither worked.

After taking apart the brake drum housing, the entire left side assembly was soaked in oil and gunk. There is also deep grooves in the axle housing where the seal sits between the drum and housing keeping back the fluid for the differential/final drive. The LH seal that had been installed was a lip seal that caused the aggressive grooves to form. LH wheel cylinder was leaking heavily into the housing. While the RH drive assembly was much drier, and the RH wheel cylinder was completely seized and gunked up. The backing plate on the RH side is wavy and bent up. RH seal is a proper oil bath seal and did not cause the same wear seen on the LH. Drive housing of the RH was turned down to 4.876, to what I assume would be to fix the grooves that the LH now has. Surface of the RH looks fine. All brake shoes have shims welded on to the bottom side of the shoe, it appears that the brakes were modified (I think the back plate bottom ends as well) as they do not look like what the manuals show.

After having everything apart, I noticed that there was no mechanism to engage the brake shoes with the hand brake. The entire hand brake mechanism just beyond the transmission is completely gone. No cables or hardware inside the drum housing.

My plan is to turn the LH drive housing down to 4.876 and replace both seals with 370195A (non-contact oil bath seal) that will prevent grooves from being worn on the housing surface. I will also be replacing the castle nuts as they are pretty chewed up from pliers and improper tools before my ownership. Beyond ordering the brake cylinders and shoes (looking like I will have to mod them), is there any place to source the hand brake components? The lever brake linkages in the drum. I would like to have the hand brake working for safety and parking, but looks like something I will have to fabricate myself.
