Discuss the Procedure for Bleeding Brake Systems and its importance Importance of Bleeding Brakes  Brake systems only work as intended when there is no air present anywhere in the network of brake lines.  Unlike brake fluid, air is highly compressible: o Pressurized brake fluid will compress air bubbles before acting on the calipers and/or wheel cylinders.  Normal braking events typically displace less than one milliliter of brake fluid: o Large volumes of air in the brake system could prevent the generation of usable pressures. o This condition equates to a sudden and catastrophic brake system failure from a safety perspective.  Some brake service/repair procedures could introduce air into the brake system: o Caliper and wheel cylinder replacements. o Caliper seal or piston replacements. o Rubber or steel brake line replacements. o Master cylinder replacements. o Any repair procedure requiring brake line joints and junctions to be undone or disconnected.  Tools and Equipment for Bleeding a Brakes: Tools and Equipment for Bleeding a Brakes: Tools and Equipment for Bleeding a Brakes: Tools and Equipment for Bleeding a Brakes: Tools and Equipment for Bleeding a Brakes: 5. Clean Cloth or Paper Towels: To wipe off any spilled brake fluid and to keep components clean. 6. Assistant: While not a tool, having someone to help pump the brake pedal and monitor fluid levels during the bleeding process is extremely helpful. Tools and Equipment for Bleeding a Brakes: Optional tools include: 7. Turkey baster or syringe: Useful for removing excess brake fluid from the master cylinder reservoir before beginning the bleeding process. Tools and Equipment for Bleeding a Brakes: Step-by-Step of Bleeding A Car: Step-by-Step of Bleeding A Car: Step-by-Step of Bleeding A Car: Step-by-Step of Bleeding A Car: Step-by-Step of Bleeding A Car: Step-by-Step of Bleeding A Car: STEP 6: Top off the brake fluid level strictly to the “Maximum” mark on the reservoir and clean up all brake fluid spills. Note that since brake fluid is water soluble, brake fluid spills on the hubs and calipers can easily be removed by spraying the hubs with a garden hose or pouring clean water over the hubs with a bucket or similar implement. Next, fit the wheels, and lower the vehicle to the ground. Test the brakes by test-driving the vehicle in a safe environment to verify that the brakes work as expected. Step-by-Step of Bleeding A Car: Step-by-Step of Bleeding A Car: During the brake bleeding process, several issues can arise that may hinder effective bleeding or compromise brake system integrity.
