• Q: How to service and repair the Brake Master Cylinder on 2000 Cadillac Eldorado?

  A: You need two brake pipes and two nuts to build seals for master cylinder outlets. Use a tube fitting nut 11x1.5 mm and a 12x1.0 mm one with two 4.75mm brake pipes 100mm long. Anaerobic power flaring creates the end of each tube followed by attaching threaded nuts onto these flared parts. Hold one straight tube end in a vise using gentle force until it bends to 90 degrees at the heart of its compression. Then release it from the vise. Set the tube back into the vise and bend it to seal itself tightly. Use the fabricated plugs to seal the master cylinder outlet and set the vise gently to prevent damage. Place a master cylinder in a vise and flex down the handle facing to drain fluids while keeping the section surrounded by towels to catch spills. Introduce new brake fluid into the master cylinder while observing that increased Piston resistance against air during strokes will keep it from going past its stop position. Use a tool with a smooth end to pull the primary Piston in 25 mm (0.948 inch) motions about 3 times and then restore the master cylinder to the vise while tilting it upward to repeat the same strokes. Mount the master cylinder in the vise and turn bolt plugs one by one while pushing the primary Piston down to dump air from the cylinder. After you push the primary Piston back in place you should fasten the plugs to seal the system. Continue the operation until all air passes through the plugs and put the master cylinder back into the vehicle.
