Getting a spongy feel on your brake pedal? Then it’s high time you bleed your brake system. A spongy or resistance-free brake pedal means there’s too much air that’s taking up the space of the brake fluid.
Bleeding your ride’s brake system is easy. All you have to get is a wrench that would fit the bleeder screw, a container, a rubber hose that would fit the bleeder valve, new brake fluid, and a buddy to help you out. Here’s how you do it:
1. If you don’t have a garage to work in, just park your car on a flat surface where you can have enough space to work around your vehicle. Engage your ride’s parking brake.
2. Open your car’s hood. Find the brake master cylinder reservoir.
3. Take out the old brake fluid from the reservoir. You can use a turkey baster or battery solution filler to siphon the old fluid out.
4. Top off the reservoir with new brake fluid. Make sure you use a brake fluid that meets the specifications set by the manufacturer for your vehicle.
5. Lift up your vehicle using a floor jack. Lift the front first and then the rear. Support your vehicle with jack stands on its frame rails and pinch weld points. Never depend only on floor jacks to support your vehicle.
6. Beginning at the rear, take off either the left or right wheel assembly. This should be easy to do with these easy-to-follow instructions on wheel replacement.
7. After you’ve removed the wheel, locate the brake bleeder screw. It should be on the brake caliper or brake wheel cylinder.
8. Attach the end of a rubber or plastic hose onto the bleeder valve. The hose can be as short as 1.5 feet. It just has to be long enough for you to be able to dip its other free end into a container filled that’s partially filled with clean brake fluid. To be able to monitor the flow of the brake fluid, it would be best to use a clear hose and container.
9. Have your buddy pump the brake pedal for about 5 to 10 times before holding it down with constant pressure.
10. Using a wrench, slowly loosen the bleeder valve by about 3/4 turn. With your assistant holding the pedal down with constant pressure, the pedal should slowly drop to the floor as old brake fluid and some air bubbles come out of the drain hose.
11. When there are no more bubbles and old fluid flowing out, tighten the bleeder screw. Have your assistant release the pressure on the pedal. Don’t release the pedal before you close the bleeder valve as it will suck air in back into the brake system.
12. Repeat the bleeding procedure (steps 7 to 11) until no more air bubbles and old brake fluid are coming out of the drain tube.
13. Once you’ve completely bled the system, check the brake master cylinder and refill it. Don’t allow it to be completely drained.
14. You have just successfully bled the brake line in one of your wheels. You just have to follow the same steps for the rest of your wheel cylinder and brake caliper assemblies. Just remember to bleed the rear wheels first.
15. After you’re done with all the calipers, do a final check on the master cylinder. Refill if necessary. Check the firmness of the brake pedal. Put the wheels back and lower your vehicle. Go for a test drive.
The entire bleeding process may require quite an amount of brake fluid. Though it would allow you to save, it’s not advisable to reuse brake fluid that’s been bled out or mixed with the old fluid. This is to ensure the quality of the fluid in the system. To make your brake fluid last, just protect the system from leaks and keep its brake pads and shoes maintained.
