Add brake system at the rear axle

[HelloPitty]

Is it possible to add rear axle brake system in a car that didn't have it?
How much would it cost if it is possible?

In theory its possible, is it worth it? you have to find a kit to be compatible with the ibiza and i think it wont be cheap.

Is it that complex? I mean, between weaker versions and more powerfull versions, does chassis and all other components changes that much? Like from a Seat Ibiza 1.6Tdi (2020) to a Seat Ibiza FR (2020), is it that different? I had the idea that most of components were the same with a few changes to accomodate the visual and mechanical changes between the versions. I mena, for instance, isn't the engine of 1.6Tdi the same as the FR versions but with the power output capped dow to lower values?
