"Thems the Brakes"Part 2, Fluid Refill and Bleed
Brake Fluid: The enemies are moisture, heat and time. The fluid needs to be refreshed. Every 2 years minimum.
The Refill: I don't call it flushing, because you can never really replace all the fluid. Start by siphoning as much fluid from the Master Cylinder reservoir as possible, using a turkey baster or some other suction device. Leave at least a half inch of fluid over the intake ports. If you get air in the Mas Cyl then you'll have to bleed it separately. (not fun)
Once you have removed the old fluid, gently pour in fresh fluid from a new bottle, trying not to stir up the old stuff in the bottom. Fill to the full mark and set the reservoir cap on top to prevent any debris from entering.
The Bleed: There are many ways to bleed brakes, pressure, suction and the old fashioned tried and true method.
You need two people, a glass jar with at least a half inch of clean fluid in it, a clear plastic tube, and the proper wrench for the bleeder screws.
* Starting with the wheel furthest from the Mas Cyl, attach the hose to the bleeder screw, and hold the jar above the caliper with one hose end in the fluid. Get your partner in the car to hold the brake pedal down as if stopping, while you open the bleeder screw. Have them say "down" when the pedal goes to the floor. At the same time, close the bleeder screw. Repeat the procedure till the fluid is clear and free of bubbles. You may have to pump the brake pedal a few times in between pushes to get "good pedal." In between "pushes" tap the caliper lightly with a rubber mallet to encourage bubbles to the top. When done, check bleeder for tightness. Refill Mas Cyl after doing each wheel. Repeat procedure working from the furthest wheel from the Mas Cyl to the closest. When done pump the pedal, it should be high and firm. If not, start the engine and pump the pedal a few times to cycle the ABS pumps and valves and re-bleed. Top up fluid to full. Check for leaks by pushing the brake pedal hard and checking for fluid weeping. Snug up bleeders if weeping. Check you brake fluid frequently especially if pedal feels spongy or brake light comes on! Any leaks from calipers or hoses require professional attention. Next Part 3, Rotors.
