Do not reuse brake fluid which has been bled from the brake system. When filling the system, always use clean, fresh brake fluid.
- Insert a clear vinyl tube into the bleeder plug on the master cylinder or the wheel cylinders.
If the master cylinder has been overhauled or if air is present in it, start the bleeding procedure with the master cylinder. Otherwise (and after bleeding the master cylinder), start with the wheel cylinder which is farthest from the master cylinder.
- Insert the other end of the tube into a jar which is half filled with brake fluid.
- Have an assistant slowly pump the brake pedal several times. On the last pump, have the assistant hold the pedal to the floor (fully depressed). While the pedal is depressed, open the bleeder plug until fluid starts to run out, then close the plug.
If the brake pedal is depressed too fast, small air bubbles will form in the brake fluid which will be very difficult to remove.
- Bleed the cylinder before hydraulic pressure decreases in the cylinder.
- Repeat this procedure until the air bubbles are removed and then go on to the next wheel cylinder.
