Hello all,
I thought bleeding the brake fluid would be a good 2nd step to renew various fluids on my car - I have already flushed my radiator few weeks ago. This procedure was taken from the Haynes book p.152
Here are the
tools used:
5 mm hose, fresh brake fluid, disposable bottle, and a 9 mm wrench.

As you can see I have immersed one end of the tube in the fresh brake fluid and fixed the tube by tightening it in a hole cut in the bottle's cap. Immersing the tube in oil is important to prevent air from entering into the circuit through the nipple when opened. Haynes book recommends using a tube with a non-return valve.
Then the other end of the hose was inserted around the nipple which was then loosened two notches. Then I started pressing the brake pedal to push the old oil out of the system into the bottle.

To my surprise here is the old brake oil coming from the circuit beside the fresh oil.

Please note you need to watch that the brake reservoir does not go below the min level and that you keep on adding brake fluid as you bleed the circuit. In this case to prevent air from entering into the circuit from above.
