D5G LGP park brake adjustment?

[Hopuser]

My mechanics are struggling to figure out how to adjust the park break on this dozer. The dozer park brake wont hold on a 3to1 slope and the service brake wont hold as well?
Any Ideas?
Looked at the operators and service manual called CAT and they have no Idea!
Thanks Kris

Machine Serial Number (there are 5 different S/N prefixes of D5G) and an e-mail address please. Send them to me by PM if you don't want to post them here. I'll flip you the relevant pages of the service manual regarding brake testing & adjustment.

Your brakes are likely worn out. If you have a hystat they have disc brakes behind the drive motors, spring apply oil release.

I know nothing about D5 G But with my D4 H the brakes were naturally ON and applying brake required oil pressure.
Therefor machine has max brakes with eng stopped. Also if wont hold with engine off,would surely mean rather serious problems.
However I found linkage adjustment was not releasing pressure,and was a very easy fix.
Perhaps your machine is hydrostatic ??? In that case treat all the above with the ignorance it deserves.
