Squeaky v-brakes problem solved
i had a slight problem with the v-brakes squeaking loud, problem came from when i was installing ceramic loose bearings in my hubs i got some grease and oil on the rim and pads and that was causing my brakes to squeak.
so all i did was to wash the rims and brake pads with dish washing liquid and hot water to remove all grease and oil from the rims and pads and everything now is just fine.
FYI, lubricants and rims and brake pads don't go together so don't get them mixed with one another.
