wild pigs n. poorly adjusted brake pads that squeal in use.
From the Dictionary of Mountain Bike Slang
If you suffer from wild pigs there are a couple of things you can try. First, make sure the pads are aligned correctly and angle them so that when the brake is applied the front tips touch before the backs. To put this another way, if the wheel is rotating this way: ---> the pads should be angled like this \ but shallower.
Next try
cleaning the
rims and pads with a non-metal
scouring pad and
rubbing alcohol or bike degreaser. If you pads are fairly old, or you do a lot of riding in the mud, you might need new brake pads. You could also try
sanding the rims with a medium
emery cloth, which will remove built up crud and roughen the braking
surface. If you have
linear pull brakes a
brake booster might also help by increasing the
power of the brakes.
