A4 B8 - brakes applying

[Sammie]

When I’m driving and I take my foot off the accelerator the brakes seem to be applying without me touching the brake pedal - when I press accelerator again seems to stop - but happens as I lift off each time -  any ideas what May be causing this?

Silly suggestion - check your floor mat and make sure it hasn't ridden up and is fouling the pedals...

[Sammie]

No not the mats - but good thought 😁

Sticking caliper? Is there any burning smell or excess heat from any of the wheels when you park up.

Back right seems to be hotter than left - going in to mechanic next week to look at them - thanks 😊

You're welcome. I'd suspect it's that caliper
