Megado - The warp does not come loose from the warp beam when the warp is advanced.

Possible reasons:

1. The brake pedal has to be pushed in further.

2. The warp tension you use for your project is too low to pull the warp from the warp beam. This can happen if you make a small cloth from fragile material. In this case you will need to advance the warp beam a little by hand, while you push the brake pedal. If you weave with a low warp tension, the lease sticks, if left in the warp, could give too much restriction to allow the warp to be moved forward. Remove the lease sticks from the warp.

3. The brake cable crosses itself on the brake drum. The cable makes two turns around the brake drum. The cable must lay on top of the drum and not cross over itself, which causes the cable to hold on and not release when the brake pedal is pushed in. To release the cable again, it is necessary to remove the tension from the cloth beam by disengaging the two springs that hold the moving breast beam and taking both ratchets out of the ratchet wheel.  Now you can turn the warp beam back a bit and the cable will come loose so you can position the brake cable properly. Do not forget to put the springs for the moving breast beam back in place again.
