    I know! I was actually coming home to put my feet up with a cold beer and maybe have a quick nap in the sunshine in my hammock... now I appear to be jacking up the camper and 'whipping off wheels'!

    The drivers side wheel is catching more, and does sound a bit like a brake pad dragging. No play in the wheel though.

    My pickup used to be terrible for this. I just used to brake heavily a few times and it eased pretty quickly.

    Passenger side brake pad definitely rubbing on rust, but hub has play in it so maybe wheel bearing needs attention as well.

  9. Have you changed the brake fluid recently?

    Just over a year ago if I remember correctly.

  11. How much movement have you got, gripping the top and bottom of the wheel?
     
  12. Great, so chances are it's just sticking a bit, rather than corrosion inside the caliper's piston. You need to see if you can free of the caliper.

    Edit.
    At this point I'd remove the pads and give it a good clean and see if you can free the caliper.

    A millimetre or so? Enough to bang a bit.

    I think we are now rather out of my league, removing pads and freeing callipers. With help I’d give it a try, but on me own, I don’t think so.
    I’ll have a look at the drivers side as I’ve got it jacked up, but I think I’ll book it in at the local garage.
    It’s not a ‘specialist’ (the bloke who normally looks after Clem is busy doing his own stuff at the moment, although I’ll message him on Monday in case) but I figure a normal garage should be able to do brakes!! They look after my car okay.

  15. The wobble will hopefully just be a loose bearing , easiest of jobs to do .
    Once the wheel is off pull off the grease cap and adjustment is by slackening off the locking collar (6mm allen key) and turning it slightly one way or `tother using the allen key as a `handle` to turn the collar . The bearing is tapered so as you tighten it with the key it`ll tighten up one way and slacken off the other .
    Not too tight on the bearing though , gently nip it up and back off 1/8th of a turn ..
    (Haynes pictures help ??)

    Job done - hammock and beer :thumbsup:

    :hattip:

  16. The way the caliper's work means they need to move in and out reasonably freely, you can put loads of force via the pedal to stop a heavy bus, to push them in, but there's no reverse force of that to get them to return to off, just the fact they are no longer under pressure. So if they get dirty or a bit rusty they can stick on. Sometimes a drive with couple of sharp stops helps free them.

  17. If you're not confident and you trust the garage, and a little shopping trip doesn't free the cailpers, then, yes, brakes are brakes.

    I’ll have a look at Haynes (no! Not Bazza!!) and see if I think I can give it a go. But tomorrow now, when it’s not so sunny.

    Thanks for all the help, at least it does sound like it might be something simple

    Why don't you have a go, there's plenty of YouTube films and help on here, youve got loads of time and once you've done it once you'll always be able to do it, go on what have you got to lose, and if you really get in stoom ask Clem to come around to dig you out

    If its just making crunchy noises, using the brakes clears that up fairly fast. Instead of engine braking just wait until that red Mini is more than 6 inches off the rear bumper. Then stop the bus firmly on the brakes.

    Despite most people not believing it, I did once have a wheel bearing go from silent to grinding.. went over a cattle grid towards Beaulieu at 40mph and the vibration and noise from the grid just kept on going, maybe quieter but similar...
