T32 Front Brake Partly Sticking When Warmed Up

[ChestnutBrown]

My T6 T32 has developed an issue with the front passenger side brake appearing to stick intermittently once up to normal driving temperature. It gives me the feel like it’s grabbing for part of a rotation which I can hear and feel at speed. When stopped the temperature is more noticeable on passenger side, which suggests that side only.

Has anyone had issues with sliders sticking once warmed up? Alternatively, could it be an ABS Sensor perhaps?

I plan to investigate further on Saturday but always good to have parts ready if there’s a common issue.

I am also wondering whether the disc could be warped, as it gives me a jerky feel at slower speeds which suggests it’s the brakes coming on and off or pad touching disc for only part of a rotation.

Any ideas to consider in advance?

I would remove the pads and check the discs and pads for odd or uneven wear etc
Unbolt the caliper and give it a good clean, pump the pistons out a touch for more of a clean around the edges and make sure they retreat ok and no pistons are stuck/seizing
Not sure you can do much more without replacing bits

I am thinking about getting a replacement caliper in readiness, just in case. Euro Car Parts usually stock them but my Van comes up as an Arteon on their website, despite being fine elsewhere.

Anyone have any idea on a part number for a Pagid reconditioned front left for a T32 340mm disc size?
