Explain why it is important to check your brake fluid regularly, be sure to explain what happens to the fluid when you step on the brake of a car and how that fluid then acts to make the car slow down, then explain why it is important to make sure that your car always has an adequate supply of brake fluid.
it takes fluid before the brakes can work ! the master cylinder pushes the brake fluid to the calipers and the caliper pistons comes against the pads and the pads goes against the rotors to stop your car ! if you had no fluid then the master cylinder would have nothing to push !
ok.When you press the brake peddle to work a piston in the master cylinder that uses brake fluid to make pressure. the pressure makes the brake caliper pinch the brake rotor disc to slow the the car/ stop . No fluid , or contaminated fluid will not allow the brake system to work things that can get in the fluid that can hurt the system , any fluid other than proper grade brake fluid, water, air all those thing effect the system and can cause it to fail.
The action of pushing the brake pedal actually pushes a rod that's attached to it. You can't see the rod unless you look up under the dash. The rod pushes a piston inside your brake master cylinder. The piston forces some but not all of the brake fluid into the lines to pressurize the brake system by either pushing the piston in a brake caliper thereby pushing the brake pad against the rotor in a disc brake application, or, pressurizing the wheel cylinder thereby pushing the brake shoes against the drum in a drum brake application.When the pedal is released, the pressure is relieved, and the fluid returns back to the master cylinder. There is always some fluid in the lines but not all of it. The principals are the same for any hydraulic brake system. With an anti lock system, there is a solenoid controlled by an on board computer that basically pumps the brakes for you to help prevent wheel lock up and loss of vehicle control. If you don't check the fluid level regularly, the level could drop too low and allow air into the system. Air compresses where the brake fluid doesn't so when there's air in the lines the brake system won''t function properly because it can't build enough pressure to apply the brakes. The fluid level is also a good indication of how much your brake pads and/or shoes have worn and if they need to be replaced before they wear out completely. The lower the fluid level, the more worn they are. Brake fluid also is known to attract moisture. If you have a bad seal on your reservoir cap, moisture can get into the system and cause accelerated corrosion of it's parts leading to brake failure.
