The task of removing the master cylinder from your Jeep Bendix 9 anti-locking brake system is relatively straightforward because there are few bolts that secure the master cylinder to the vehicle. The master cylinder holds the excess brake fluid not in the brake lines or the brake calipers. When you push on the brakes, the hydraulic pressure of the brake fluid located in the master cylinder pushes on the fluid into the caliper and forces it to close. Subsequently, the brake pads located inside the caliper grab onto the brake rotor to stop the Jeep.

Remove the cover off the master cylinder by pulling the metal snap rings off to the side.
2Loosen the lock nuts that secure all four of the brake lines to the master cylinder. When you pull the first brake line away from the master cylinder have a bowl ready to catch the brake fluid as it drains from the hole left by removing the brake line. Once the fluid drains, remove the other three brake lines from the master cylinder.
3Loosen the large nut that secures the master cylinder to the brake assister. The brake assister looks like a large bowl attached to the firewall on the driver's side of the engine bay. Turn the large nut away from the brake assister and closer to the master cylinder.
4Turn the master cylinder counterclockwise to thread it off the brake assister. Some brake fluid will spill from the joint between the master cylinder and the brake assister; wipe it up with a towel.
