how do you fix a vauxhall astra hand break cable

Assuming that there is no break in the cable , the repair can be made with electrical tape encircling the frayed section of cable .

The shift cable usually doesn't break. The bushings on the shifter inside the cabin have been known to break, or the clips that hold the cable to the tranny fall off allowing the cable to come off the tranny. I would check these points first before replacing the cable.

It does depend on what the problem is. The most common thing to go wron on headphones is a break in the cable near the jack. To fix this you can cut the cable and solder on a new jack.

If it is not a break in the cable near the cable it is sometimes a cable has come loose inside the earcup... This can be tricky to fix but be brave open them up and you may see the problem.

the rod will be stronger, but will break, the cable will bend under force, but not break. the rod has more tensile and shear strength.
