Deutz Brake Cylindern Disassembly

Here is all the parts removed so you have an ide of what is to come.

This is the cylinders placement on the center housing.

First we will remove the adjuster bolt, untighten the nut with 17mm spanner and then unscrew the bolt with a 8mm spanner.

Next remove the locking ring with lock ring pliers.

Flip the cylinder over.

Remove this bigger lock ring taking care since the spring is under some tension.

If your cylinder is in good condition you might be able to get the piston out with compressed air but mine is rusted in place.

So I used a greasegun and some special fittings. A brake pipe fitting threaded for a grease nipple.

Replace the air bleed nipple with the greasegun nipple.

Plug the hydraulic inlet and use the greasegun to force the parts out.

First comes the plunger that in this case was rusted in place.

Next the piston.

Next turn it over and use a 17mm spanner to remove the hand brake arm bolt.

Then using a scribe mark the end positions for the arm so you can get it back in the right rotation. Both the arm and the inner pusher have splines so this is a good thing to do.

Remove the arm and flip it top side upp.

The handbrake axle is locked by a small pin marked with the red arrow. I used a welder and a slidehammer to remove this.

Next use the slidehammer and a m10 threaded end to remove the habdbrake axle like in picture 2.

Remove the screw that stops the adjuster parts from rotating.

Now we will have to separate these two parts to get the handbrake actuator out.

Using a m10 bolt and a metric pipe thread I forced the to rotate in different directions which broke them free,

Now the top part can be removes followed by the handbrake actuator and lastly the lower part.
