    IMG_0692.jpeg IMG_0691.jpeg IMG_0690.jpeg IMG_0689.jpeg Hi there,

    I was driving home the other day from a trip - about 90 kms. I noticed an ocassional squeak coming from the passenger side front wheel. I didn’t think too much of it until we were nearly home, when it suddenly became a loud screech. I stopped the car immediately to inspect. Nothing obvious. So we hobbled the last 200 metres home.

    I have taken the wheel off to have a closer look. The first thing I noticed was that the dust cover smelled strange and the black stuff flaked into my hand.

    I tried to spin the wheel. It goes around but the disc seems to be catching most of the way. It takes some effort to push it and it seems to catch worse on one point. As if the rotor may be deformed?

    I attach a few photos and would love any learned opinions on how to fix this problem! Thanks and regards.

    How much friction material is left on the pads?
    edit: Here's a picture to guide you.
    You should be able to see without dismantling anything as they have already done in the picture.

    Check for play in the wheel bearings......
    If a bearing has given way/is on the way out, the wheel will not spin true and may cause the rotor to bind sporadically ... and it'll scream/grind before letting go altogether.
    Put the wheel back on, grab it firmly and try and wobble it side to side....should be almost no play at all.
    Good luck.
    Cheers,
    Mark

    Hi Wiz, they look more like your ‘bad’ photo. Maybe 10mm

    How did you go with Mark's wheel bearing test?

    Hi Mark, I did your check and there is quite a bit of play. I reckon about 5-10mm. Looks like I have a bearing and a pad problem!

    10mm on the pads is usually Ok... but if you are going to the effort of doing the bearings you may want to get the rotors checked and replace the pads at the same time.

    That much play = do not drive it until you rectify the problem.
    Cheers,

    Do T3 have the speedo cable on that side? If so does it have a rubber grommet at the back of the hub where the cable may come in.
    On a t2 if that grommet falls out, water can get in causing the bearing to seizes up.
    Just another thing to think off.

    yes, they do

    You can “just” see the cable end.
    A LOT of grunge leaked out of the bearing cap

    Also check disc wear limit. If other bits are in need of replacing, perhaps maybe too.
