Rear brake binding after caliper change

Afternoon all. Think anyone could shed some light on this?
So more often than not, but not all the time the nearside rear brake seems to stick, causing the wheel to heat up and the pads to smell.

I'd initially changed the pads, cleaned the slider pins, filed the caliper carrier to clean it, and replaced the pad shims. I also added a thin smear of anti seize grease to the backs of the pads. No change. I've now changed the caliper, so that's brand new. Still no change.

I might add at this point there's no squeaks or squeals, no fault codes for the braking system, no issues at the pedal end, no dash warning lights and the EPB appears to be functioning as it should. There was also no issues during the mot test, which the car passed two weeks ago.

Any suggestions folks?

Possible starting-to-break-up-inside flexible hose??

[SwaitsySG]

Not something I'd considered, but it's possible. How firm should the flexi-hoses be?

Thanks, - not sure I’m understanding the significance. Simply change it as a process of elimination. 
Kind regards,

Gareth.

For the sake of opinion. Cheers.

Still not sure of the significance, but…

I doubt you will feel a difference in firmness because the hoses are armoured. It is the rubber lining that perishes.

Hi the brake hoses rot from the inside out as Cliff explained, when they rot the inside collapses not allowing the fluid to return, this then holds the piston on to the pad worth changing that first as the other possible cause is the ABS unit malfunctioning which is a whole different expense.

Thanks lads. I don't believe it's the abs unit Stevey. Not when the hoses are a tenner a pop. I'll try them first. I was curious about whether being solid externally or not at least gave some sort of indication as to whether they were bad. It's an old car, and the brake pipes are going to be rusty where they meet the flexi hoses. So trying to remove them could be a world world of pain in itself.

Hi they wont be that bad to remove if you give them a good wire brushing and soak them in Plus Gas fast release overnight also if you use the right size brake spanner with the cut out that allows you to get past the the solid pipe, like a ring spanner with a bit missing, the whole job is easier.

Cheers Stevey. That's optimism i can live with, and I've plenty plusgas 🤣 I've a set of ring spanners but not any dedicated brake spanners, so maybe jump online the night and have a look for some 👍🏻
