E30 rear discs
Had some new rear discs and pads fitted (E30 325 Sport 1990) and there now
is an intermittent grinding/thumping noise coming from the near side rear wheel. I can stop it by applying the handbrake one notch but the situation is unsatisfactory. Anyone know the possible cause of the fault? David |

Could be there's muck in there, or problems with the shoes - although they've usually got a long life. But it could be other things - I'd take it back to whoever fitted them and complain. ;-) First, though, there's a procedure for bedding in the shoes - it's in your handbook. Apply the handbrake until it's just working and drive for a mile or so at low speed. -- *On the other hand, you have different fingers. Dave Plowman London SW To e-mail, change noise into sound. |

Do new handbrake parts come with a new set of discs or would they use the old bits? This is a BMW dealer doing the work! They told me nothing about the bedding in procedure for the handbrake parts which i would have thought was fairly important - the same goes for bedding in the discs. They are so busy these days (having turned into something resembling a car supermarket) they probably don't have the time to bother... David |

But they should be bedded in afterwards. But if they'd fitted new ones you'd have been charged for them. > This is a BMW dealer doing the work!

Near useless, the lot of them - or at least those I've used. If you find a good one, treat them like a rich relative about to pop his clogs...;-) -- *When companies ship Styrofoam, what do they pack it in? * Dave Plowman London SW To e-mail, change noise into sound. |
