Hello

Just been for a short drive (20 mins) nothing particularly aggressive at all and noticed a squeaky brake.
This eventually turned into quite a severe steering wobble.

Put the car on the drive and only in reverse at low speed did one of the brakes squeal, think it's O/S/F, so I left things to cool and it appears to have disappeared, although I only drove a further few test yards.

Can a hot Caliper stick on and then release after cooling ? Or am I up the wrong tree .

Thoughts would be appreciated

It can. It's probably seized sliding pins on your floating calipers.

You get special grease for caliper pins that tolerates the heat. You'll need to remove the caliper from the hub and remove the caliper carrier which has the sliding pins in it. Remove the pins (they'll need some persuading) carefully, clean them up with petrol or similar, regrease and reassemble. That should sort it.

Either that, or the pads are stuck in the caliper carrier due to being bone dry copper-grease wise, or more likely because previous owners or mechanics have kept reapplying new copper grease on top of old, dried grease contaminated with brake dust and the resultant build-up is jamming the pads. If you're removing the caliper carrier to regrease the pins, make sure you clean up the runners the pad lugs sit in too.

Opted for an exchange caliper, FNS rusted up a bit, should cure the problem. Thankyou.
