there is also a strange thing rubbing on that knurled wheel that looks like a blade.........
Some people have thrown that away....... but persevere and leave it cos its a self adjuster.......
Every time you shoot backwards and apply the brake the blade is meant to touch the knurled wheel and tighten the (adjust the) brakes up a click or knurl ........
Can't say I ever found them to be better than whats suggested above but that's what they are
And as far as direction is concerned..... Put screwdriver in and direction of handle should be upwards to adjust ie blade on top of knurled wheel....
Jack up and spin wheel whilst doing it and when wheel slows against drums your there........ If it dont slow some one put adjusters in ass about face....... no biggy they'll still work.... Just adjust t'other way........
Repeat every time you go off road...... Is it me or do drums stay adjusted for only the first 20 mins of an offroad site?
Mud makes a great grinding paste and likes to wear down your nice new brake shoes
