If you notice that the brakes are “failing” deeper than before, this is a signal that it is worth pumping the brake system. Do not delay this process, because such a defect can cause a serious accident. Keep in mind that work related to brakes, car chassis repair and other such does not tolerate delay. And if you realized that the only way out of the situation is to surrender your car for scrap metal, then contact here: https://towingandscrapcarremoval.ca/scrap-car-removal-etobicoke/.
First, decide how you are going to repair the braking system: go to a service or handle it yourself. If you chose the second way, this material is for you. The only thing is that the article is written for car owners whose car is not equipped with ABS system, because in this case you can do without specialized equipment.
To work on your own, you will need an assistant.
There are two types of brake systems: parallel and diagonal. Start the work from the far line, so that there is no air in the system after the work is completed.
Order of work in diagonal system:
back left; front left;
In the parallel type:
If there is a brake fluid leak in one circuit, the second circuit will still work. With its help you will drive the car to the service and eliminate the defect.
Three possibilities are possible:
The brake tubes have separated from the main cylinder or the air in the system is due to a decrease in the amount of fluid in the tank – pump all the brake units;
the brake tubing is detached from one wheel – just bleed that caliper;
brake tube is detached in the area between one of the brakes and the master cylinder – pump the part of the system for which the tube is responsible.
Take a clean container with clear walls; a piece of plastic tube (you can – rubber), its diameter must fit the nozzle; wrench and brake fluid.
Release the residual air – repeatedly squeeze the brake. After removing the cap from the tank of the main cylinder and pour the brake fluid. Put the cap back on.
Work with the rear right wheel. Loosen the pumping plug and fix it. Its position should not hamper further loosening. Place the tube on the nozzle, the other end is lowered into the vessel with the brake fluid. The assistant is asked to depress the brake 2-3 times to apply pressure. At the end he must lock it in the depressed position.
As you open the fitting the brake fluid will come out. It is important to check if there are air bubbles in it. If the flow rate decreases, immediately squeeze the fitting and the pedal is released. Do this until the brake fluid is bubble-free. If you see that this has happened, squeeze the fitting.
Then do the same with the other three wheels as above. Watch the level of brake fluid in the tank. The used fluid must not be used again, so throw it away.
