I'm not sure if this makes sense, however, my cheapo mtb has got just terrible rear brakes and I have no idea why, there is plenty of meat still left on the brake pads (mind you they are the age of the bike, at least 8years old and I doubt their sale value when new has ever been more than 50p)
I have changed the cables on the bike, adjusted the brakes at least 3x , there is a very very good pressure grab and action ,however they just barely stop you. The front brakes are fine and stop good.
Is this a thing or I have something else wrong?
I tried searching for replacement pads,however all I can find in the 55mm size I have are some very cheap poundshop quality ones,seems like the standard are 70mm? But I guess I need the 55mm size If I already have that,or is it possible to use larger size as well? Also what's a good brand I should be looking at?
