No, as long as they used stock parts,
you just need to find the right replacements...
I am totally familiar with Mk3 diesel underpinnings,
we are not so fortunate here..
However, most pads from 85-98
on the Golf/Jetta platform are interchangeable on US models.
(the main difference is the thickness re: vented and non)
If the parts store has it,
I would see if they have a set of pads
for a GTI 2.0 of the same year..
Then compare them at the counter, and see if they are sufficiently thinner.
Sorry, almost forgot to ask,
I am assuming the piston is totally buried in the cylinder,
and the sliders are moving well, right?
