I am looking for parts and manuals on a 955k. It seems as though the clutches are disengaging but the brakes are not being applied. The pedals go to the floor with very little pressure but seem to get a little bit of pressure after running for a while. I would like to replace the brakes but have no idea where to start.
Before anyone asks........... S/N 85J00894....... Here's a Service Manual that covers your machine. (It will not include parts information) https://www.ebay.com/p/CAT-Caterpil...der-Service-Manual-85j-64j-71j-57j/1438330689 Parts Manual can be downloaded in pdf format from Cat Publications for $89.
You might try adjusting the brakes (plus steering clutch and brake control linkage) first. See the attached. I would suggest to follow that procedure as it is written and see where it takes you.
I will try that tonight when I get home from work.
