Someone gave me an old Genie GS-2646. All the functions work except the brakes won't release. I've tried all I can think of and next step is pulling the hubs apart. I'm hoping someone here has some magic that might keep me from having to do that. What I've done and found
Hit it with a hammer, didn't help....lol
Checked brake solenoid by cracking the line from the valve body and engaging the drive motors with the joy stick (the machine is on blocks). Good flow from the valve body. I don't have a pressure gauge. What I did do was repeat the process with the line tight, run the pump/drive for a little while to charge what looks like an accumulator tee'd into the brake line, then cracked the line. Got nice spray showing there is at least some pressure building.
using the manual brake release, turn the valve CCW per instructions, pressure up with the plunger. Takes about 1.5 strokes. Brakes don't release. Bleed off the pressure by turning valve CC. Cracked the line at the hub and repeated. Good fluid comes out when stroking the plunger.
I'm thinking since the manual release doesn't work all the possible things like safety switches are moot and the actuator inside the hubs are froze up. Just seems odd that both sides are bad.
I don't have a socket to fit the wheel nut and am thinking I'll just un-bolt the whole hub from the frame and try to disassemble from the backside.
Any suggestions, other than a bigger hammer, before I continue are appreciated.
