Eliminate the contaminants from the brake system
Hydraulic brake fluid, used in the modern hydraulic brakes may get contaminated over time with moisture, water, or solid parts. Sometimes it is enough to regularly bleed the system but at some point you need a complete flush of the system.
Follow these steps:
- Look for the bleeder nuts on the vehicles brakes, they look like small nuts and you should look for them on the back of the drum brakes or brake calipers.It’s easier to work if you lift the car and place it on jack stands. Clean very well the bleeder nuts and pour some penetrating oil on it, but just on it. If you have the time do this a night before living them like that overnight and then again half an hour before starting to work.
- Put over the bleeder nut of the rear right side brake a box wrench and then connect the nipple with vinyl tubing which end you put into a container.
- Locate the brake fluid reservoir under the hood just on top of the master cylinder and remove as much brake fluid as you can from it. Now pour the new, clean brake fluid that is correspondent to your vehicle’s specifications.
- You now have to open the bleeder nut, while an assistant will press the brake pedal with the engine on. Close the bleeder nut with the pedal being pushed to the ground and refill the reservoir again. Repeat this until you see clean fluid coming out of the bleeder. Again tighten the nut, and remove the tubing. Repeat the procedures to the other wheels.
- Fill the brake fluid reservoir at the maximum level and take the vehicle to a brake test.
