Hi, I have a tag axle motorhome on an al-ko chassis and cant get it to move. It has been standing for about a month and never leave it with the handbrake on, apart from this time i forgot:bang: The handbrake seems to release as i crawled underneath and noticed the cables were fairly slack. My question is, does the handbrake operate the pads as they are discs all round or is there some other locking device? I also jacked one side up and the wheels move a fraction and then you hear a thud and then wont move at all.
Thanks in advance
 
The handbrake used on the AL-KO axle (& also the normal Fiat axle) is what is known as "drum in hat" type which is a drum type handbrake mechanism housed in the "hat" of the disc itself. From your description I would say that the drum brake mechanism inside the disc/drum has seized some how or the adjuster has wound itself on. This can be adjusted as per the below diagram & precedure but will prove difficult if you cannot rotate the disc to line the holes up.
Make sure the handbrake lever is in the completely off position
- Carry out the following on both sides of the vehicle.
1. Rotate the brake disc manually until one of the openings (1a) is in line with the toothed pin (1b) of the adjuster.
2. Insert a screwdriver and, with the assistance of an electric torch, rotate the toothed pin upwards until the end of travel position (a condition in which the shoes are touching the brake drum).
When the rotation of the adjuster stops, do not force it by rotating the toothed wheel any further.
3. Rotate the toothed wheel (1b) by about 5 teeth in the opposite direction (downwards). This operation makes it possible to re-establish the recommended clearance between the shoes and the drum (the rotation of five teeth of the adjustment wheel corresponds to a variation in the shoe diameter of 0.15 mm). The disc will then rotate without sticking but can produce a certain resistance.
You could also try jerking/pulling down on the handbrake cables to try & see if that will loosen whatever is seized in the mechanism.
