E46 318i Touring: Handbrake / parking-brake repair + adjustment

The handbrake (e-brake) wasn't working properly on the left side of the E46 Touring, which I assumed would either just need adjusting or at worst the spring mechanism had failed. BMWs of this era have a drum-brake mounted inside the hub of the disc-brake that is used only for the parking-brake. It turned out that the sprung stud that holds the lower brake-shoe in place had come loose, worked its way round the drum and partially jammed the mechanism, as in top picture.

The slot that the stud locks in to is part of the backing plate for the disc and it had bent outward and rounded off over time, no longer giving enough metal for the stud to hold on to. I managed to build the slot back up using a cole-chisel and there is just about enough metal left to hold the stud firmly. If it happens again in the near future then a new backing plate may be required, but this is a hub off job and a whole load more work, so lets hope it doesn't. 

Annoyingly, I had to crack open a new £13 handbrake spring assembly kit just to use the one sprung retaining stud, guess I have some spares at least. With the left side now working correctly, I gave both sides of the handbrake a quick tighten up using the rotating adjuster inside the drum.

E60: Front 12V Socket spring mechanism assembly.

PROBLEM:

• Mechanism has collapsed and 12V socket will not pop up out of housing.
• Ash-tray has been removed during work on car and has fallen apart.
• Coins or other objects have jammed in the mechanism and are stopping it from operating.
• The 12V socket is jammed up and ash tray will not close.

As with everything on the E60, even the mechanism that pops the 12V socket up and moves the trim around in over-designed to death. There are two springs in the assembly. A main flat-coiled spring that lifts the 12V socket up when the ash-tray is slid open and a small one that operates a tiny trim-flap that fills the gap created as the socket rotates up. You know, so everything looks neat!

These come out really easily when the ash-tray is removed from the fascia, or when things get jammed and the ash-tray is forced shut, but it is quite confined under there and the springs should not get lost. Be careful not to push them under the foam-trim at either side while retrieving them.

The main spring is on a spindle running through the socket housing, with a screw at one end. The protruding arm faces forward and tenses against a lip in the plastic. The screw will need removing to get the spring back into place, so do not over-tighten it when refitting so the socket still rotates freely.

The smaller spring slides onto the plastic stud on one side of the front socket hinge and the two protruding arms should be in a V shape pointing upwards and sit in the grooves on the hinge and trim-flap, as pictured.
