How do you tighten brakes on a 2002 Honda 400EX?

Answer 1

The only direct brake adjustment possible on this ATV is the adjusting bolts with lock nuts on the rear brake calipers. These are easily found right on that part of each caliper where the brake lever moves when the brake is pressed. Both lock nuts are loosened and the adjusting bolts tightened until the brakes are found to be suitably tight, leaving some free play at the top. It is important that this be done on both wheels as uneven braking may otherwise result, leading to hazardous operation of the vehicle. If this does not work, then several other things could have gone wrong. First, and as a part of regular maintenance, check if there is enough brake fluid in the reservoir and top up if necessary. There may be air in the brake system which needs to be bled in that case. The prodecure is basically the same for vehicles with hydraulic brakes. The brake pads may be contaminated or worn and need changing. The caliper piston seals or the master cylinder piston cups may need to be replaced, this will require dissassembly of these parts. The caliper piston may be excessively worn, stuck, misaligned or not sliding properly. The brake fluid passage may be clogged. The brake lever pedal may be bent. A final warning may be in order here. Brakes on any vehicle are its most important safety device and most owners would leave repairs to qualified service personnell as death or serious accidents can easily occur as a result of poor or wrong brake maintenance.
