Hi all. Found this site while researching issues with my 1994 Bounder 34J Chevy P3 chassis with the Hydro-Boost auto-apply parking brake system (AAPB). Yea, I did not know what I was getting into with this system
Iíve had 3 power steering pumps go out (the one that was in it when I bought it, the first replacement after 1000 -1200 miles and the second replacement that never worked from the get go).
Iím putting in a different brand of remanufactured pump this time and draining as much of the old power steering pump fluid as I can before filling it with new fluid. I also plan on bleeding the AAPB which brings me to the reason for this post.
Before I do the multi-step bleeding technique I would like to check the parking brake shoes as the manual apply foot pedal has excessive travel (almost to the forward bulkhead). Iíve got the drive line disconnected and tied up out of the way, shifter in neutral and the rig securely raised off the ground. My question is: How the heck do you (if you even can) release the auto-apply parking brake without starting the motor and before I have bled the system?
Worst part is I'm leaving (hopefully) next Thursday for the Oregon coast ! and this plays right in to my names initials - LML - last minute Louie
Thanks for your help in advance.
