I’m a cyclist. Use my bike for years now, recently i had my good v brakes sticking to my rim, every time I pressed the break...i was sure that’s it’s quite easy to repair ( usually clean and oil the mechanics)...as i was on the way in dark rainy day, i saw the halfords shop, and thought that i should fix the break, as it’s dangerous to ride...got into a shop, and after speaking with mechanics, they had a quick look...and said to me that the mechanics of my brake is bust, i need a new brake...what sounded quite unbelievable...so went on the road with still bad break. Next day, took apart the break, oiled it...it works and it didn’t fail for a last month.... And today i went to the shop to get some inner tubes for not my bike, so needed an advice, but 15min in the shop I didn’t see anyone on the floor except security...
