Brake Caliper issue ???

[Zippyworld]

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

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