brake pads shot, warped rotor, or bad wheel bearing/hub
Dual diagonal braking is where the brakes are on two systems right front and left rear as well as left front and right rear. This is to give even braking in a partial system failure
Left foot braking is only undesirable if you are not proficient doing it. For those that are comfortable employing that method of braking, it works very well. Choose for yourself. It's not illegal, so make the decision yourself whether to left foot brake or not.
Generally, yes. The binding caliper causes the pads to rub against the rotor heating the pads and rotor up. Hot pads and rotor provide less braking under equal pressure (when braking) so the right brake works better. The car will pull toward the better brake.
Check the rotor, it's probably warped.
Check wheel bearings - quickly! Very dangerous left unrepaired!
The bushings on the shift linkage need to be replaced
because the left wheels gets pooped on
It's secured to the frame under the tank on the left side. You'll need to remove the tank to get to it (not a hard job). The filter is secured with a rubber contraption to prevent vibration rattling it around under the tank. Gentle use of the pliers on the fuel's male ends will get the fuel lines off.
It left Russia's problems mostly unsolved
It depends on where it is on. Normally the braking force is balanced on an axle but different between axles. i.e., the braking force between left and right brakes on an axle is the same but the braking force on the front axle might be greater than the rear.
To indicate that you are braking while riding a bicycle, you should use your left hand to extend downward with your palm facing backward.
sounds like your brakes need bleeding properly
