Smoking rear wheel!!!

Morning all,

Have had sqeeking wheels for the last few weeks and it was difficult to pinpoint which wheels it was coming from, applying the brakes made it completely go away, after a short drive back home yesterday 2 miles i pulled up and there was smoke pouring from the rear drivers side wheel, the rim was red hot. Thought it might be the hndbrake seized on but adjusted that today to no avail. I couldnt even remove the rear wheel as it appears to have seized on due to the immense heat!! any suggestions would be much appreciated

A rear caliper will be seized on for some reason. You will need new rear discs and pads and new or replacement caliper. It's not a good idea to free off the seized caliper and use it again if it has been as hot as you describe.

To get the wheel off, wait til everything has cooled down (about an hour), loosen the wheel bolts and jack up the car, then beat the tyrewall (not the wheel, cos it hurts ) alternately on the left and right until it starts to free up. once it's off, use a wire brush to clean the hub ring and surface (do the same on the inside of the wheel mounting surface), then apply a little copper grease to the hub mounting surface for re-fitting. The same applies if you can't get the brake disc off, but instead of your hands, use a rubber mallet (if you are replacing the disc) to the inner side of the disc.

The seizure may be a split dust seal that's allowed dirt in and caused the piston to corrode.

I don't want to add to your worries but it may also be worth checking for wheel bearing play if it's been like that for a while, as the excess heat can cause premature bearing failure. Seen it happen on a Fiat Coupe before, luckily the faiure happened at low speed.

The handbrake is an automatically adjusting system so if you've fiddled with the cables at the lever end its probably over adjusted now. Anyhow your problem is due to a seized rear calliper which is very common. Depending on how badly its seized you may need a new (or second hand one) plus pads and disk and as previously said the heat may have damaged the wheel bearing by melting all the grease away!

You may need to use a fair bit of force to get the wheel off, If you are going to jack up the car then stick an axle stand under there as I wouldn't really trust it on a jack (a big trolley jack perhaps but not the supplied wheel changing effort.)
