valver front brakes are dead easy to dissassemble and put back on. Two bolt hold pad carrier on, take this off, tap pads out. Now hard bit, unudoing hose union, only because they can be solid and quite rusted. Then plug this with a matchstick or something, and undo two other bolts that hold rest of caliper on. Take to bench and clean paint and free of piston if sticky. Then bolt back together, with new pads (little coapslip on back of them). Push pistons back to make room for new pads and discs (I do it very slowly with a G-clamp). Bolt up everything (little thread lock on bolt threads wouldnt go amiss), do other claliper and bleed them. sh*t just noticed you are putting 16v calipers onto a 1.4 rt. So not totally sure, if any mods would be required, i.e caliper holes locating differently, but good chance it will go straight on
