Sorry for the long hijack but bought a full set of flat mount calipers with flat bar levers looked to have all fixtures fittings and mineral oil everything, so takes me part built bike to lbs for the kit to be fitted 3 days later pops in to shop and the lad fitted front brake and it worked a ttreat but said there was a ferrule type thing missing saying he would order one for the rear, fine I thought goes back a few days later all done and dusted but needed 2 hydraulic kits which looked like olives and pipe inserts saying it’s what the brake pipes needed because they had to be cut I definitely know these where already in the brake kit. Then the punchline £48 . Does any of this sound like anything like the truth??
