Front wheel hub getting Hot

[PROJUMPER]

Hi All,
I had an issue with the ABS warning light coming on, I changed the speed sensor and reset the ABS lights and all is working ok.
When I pulled up at home yesterday the N/S front wheel was hot, would this be anything electrical or would it be more likely the pistons in the calliper not returning properly?

How hot was the wheel on the other side ? You may just have been braking a lot ? If it was just that wheel though it does need investigating , probably as you say caliper or wheel bearings

Some discs have a built in immersion heater winter pack that gets the discs all toasty to melt any ice and snow before setting off.


Seriously though . Discs maybe warped or wheel bearings have been over tightened.Sticky caliper.

Only the N/S wheel was hot, O/S cold!

Well new discs in December, I will prompt for "sticking calliper"

That requires investigation. Jack up that side, does it turn freely? Go from there.

There should be a small amount of play bin the bearings and they should spin freely and smoothly.

Until I got my w211 front bearing replaced there was too much play, this caused a V slight bind.

As above, jack the car and rotate wheels to see if one has more noticable drag than the other. The caliper piston may need cleaning up, or the 'metal' pad locators may need greasing if they aren't sliding back and forth freely in the caliper and one is resting against the disc.
