You've reminded me of another. That shim/anti-squeal kit is included in factory and Mintex kits. A Teflon shim. Pattern pads don't work as well.
Front Pads: - PATTERN MANUFACTURERS USUALLY ONLY SELL ONE TYPE OF PAD WHEN THERE WILL BE THREE
Factory pads are high-powder, whereas many pattern pads are sold as low-powder, actually something that is sold as a virtue! And sucked-up as such. [Often the reason for f&3kw$t boy-racer warped-discs threads, it'll be a pad issue]. Mintex are on eBay and come about 60% dearer but work and make powder like factory sets and bed down well.
NOTE: There are three pad types for the front and if you remember your school-boy physics you'll realise why. If you've just plonked on the first set you or your parts seller could see, REMEMBER: PATTERN MANUFACTURERS USUALLY ONLY SELL ONE TYPE.
Clearly the 'Laws of Physics' do not apply to them.
And if you've been to school and you still don't know why there's three, clearly the state has frittered money educating you. Because you would certainly have been taught this. Please for all our sakes, leave your brakes alone.
Fortunately, the people at Mintex were not donkeys in school.
