GFT Brake Repair Instructions
Remove the two motor bolts and the motor.
Secure a fixture*, as shown in the picture, to the drive. The bottom plate of the adjustable center screw compresses the brake back-up plate, until the snap ring is axially unloaded.
Free the snap ring, remove the fixture and disassemble brake.
The piston releases easily by applying air pressure to the brake release port.
Follow reverse procedure for brake assembly.
* A simpler fixture would be the same crossbar with two additional trapped holes above the exposed area of the back-up plate. Secure the bar to the drive and use two bolts with sufficient length to compress the back-up plate evenly.
Lubricate the piston seals, back-up rings and their contact areas with gear oil.
Assemble back-up rings prior to piston seals.
