Ford Mazda Brake Master Cylinder TRQ BCA52050

Thank you for your inquiry! 1. Fill the system with brake fluid — ensure the brake system is full of fluid before beginning. 2. Build pressure — operate the master cylinder to build pressure in the system, then hold it pressurized. 3. Open the bleeder valve — each wheel has a small fitting called a bleeder valve, located either in the caliper or wheel cylinder. 4. Release fluid and air — opening the bleeder valve allows fluid and trapped air to bleed off. 5. Repeat as needed — this process is repeated as many times as necessary at each bleeder valve until all trapped air is removed from the system.
