Default Smoke without fire

As the car had been idle for a fortnight I went for a little drive yesterday p.m. Included was a good workout on a nearby by-pass. When I slowed/stopped for traffic lights I noticed some smoke from the off-side front wheel-arch. Stopped at a lay-by, bonnet up, all seemed well other than a burning smell around the wheel -arch. Drive home uneventful.

Brakes or something else?

Cool

Could be a collapsed flexi pipe has caused the calliper to seize and push the piston against the disc thus stopping the piston to return.

That's what happened on mine. Fitted a new pipe and calliper and all was well again.

Sticking caliper maybe with it sitting.

Was the wheel hot?

Don't touch the disc to see or feel, if it's hot!

Not that I did that, or anything.

99% sure it will be a sticky caliper, they tend to seize up if stood a while.

Spit on your finger then a very quick light dab is safe enough - if it sizzles the disc has got a tad too warm.

Stings a bit doesn't it? (Blister on my index finger took ages to heal...)

Measured the temperature near the calliper with a digital thermometer probe on front and back wheels. Fronts were warmer than the rear and offside front the hottest. Guess it's a sticking caliper.

How, if at all, do the front brakes differ from those of a Rover v6? Are the requisite bits commonly available?
