Bleeding your brakes.
When bleeding brakes I would recommend using a vacuum
brake bleeder - its a very fast and clean method. I use
a vacuum pump with a bottle connected in series to
collect the brake fluid. Obviously you have to keep an
eye on the level of fluid in the container, as if it was
drawn into the pump damage would result.
If you have an air compressor you can buy a vacuum brake
bleeding kit - this consists of a vacuum generator, and
container to collect the brake fluid.
