1
Remove the top of the master cylinder reservoir.
2
Using a turkey baster, suck out as much of the old dark inky fluid as you can.
3
Clean any sediment out of the reservoir with a clean, lint-free rag. (Do not spill any brake fluid on any painted surfaces, it will remove the paint immediately.)
4
Fill the master cylinder with clean brake fluid.
5
Replace the top of the master cylinder reservoir.
6
ask friend to Pump the brake pedal several times (15 or more).
7
Using a spanner that fits the bleeder bolt, loosen the bleeder valves, but leave them closed. (A little penetrating oil drizzled on the bolts the day before will help to loosen them).
8
Using a piece of clear plastic tubing (aquarium tubing works fine), push one end of the tube over the brake bleeder bolt.
9
Put the other end of the tube into a small, clear bottle with an inch or two of clean brake fluid in it. (This will keep air from being sucked back into the brake cylinder.)
10
Put a piece of 1 x 4 lumber or some other "spacer" under the brake pedal to prevent the pedal from traveling too close to the floor.
11
Remove the top of the master cylinder reservoir.
12
Top off the master cylinder reservoir with fresh fluid.
13
Replace the top of the master cylinder reservoir.
14
Have your helper sit in the driver's seat and slowly depresses the brake pedal with an even force and hold it down. The helper should shout "down" when the pedal is down as far as it will go.
15
Starting with the rear passenger wheel (back right for right hand drive cars), turn the bleeder bolt to the left one quarter-turn. Old fluid and air will go down the tubing into the bottle. When the fluid stops, close the bleeder valve.
16
Shout "up" to your helper, who at this point should remove his foot from the pedal allowing it to move up.
17
Repeat this process until new, clear fluid comes from the bleeder tube. (After every five (5) times the brake pedal is depressed, top off the master cylinder reservoir with fresh fluid. Never let the reservoir get too low, or air will be sucked into the master cylinder.)
18
Tighten the bleeder bolt.
19
Repeat steps 14 to 17 on the left rear wheel.
20
Repeat steps 14 to 17 on the right front wheel.
21
Repeat steps 14 to 17 on the left front wheel.
