In normal use you should never be able to lock the rears, why do you think brakes are smaller on the rear? Rears do very little braking in normal use. The brake rollers you are describing are purely to test brake balance and efficiency. There is nothing wrong with your car, the brakes are...
Looks like you did a good job there, I'm thinking I should really do the same to my 2017. Could you tell us where you get the rest of the parts? Fittings, teflon hose etc.
Thanks.
Just got my front screen replaced today as well, very happy, OE screen installed well (I was there the full time) by autoglass. I paid £190 excess, can’t really complain at that.
I stay by the coast and have always had rust problems with my vehicles, so I got mine done here..

Seems to be a good job as far as I can see.
