Master Cylinder

Draining the brake fluid must be the first step before removing the brake master cylinder while you need to immediately clean painted surfaces that get in contact with fluid. After you remove the battery and battery tray you must separate the battery carrier. When servicing manual transaxle vehicles you need to unlink the clutch reservoir tube through the process of sliding the clip then taking it off. The brake pedal should be depressed several times as a step before brake master cylinder removal to release vacuum pressure from the brake booster. Unplug the connector which provides signal to brake fluid level warning. The required tool of 09023-00100 for this operation allows users to split the 3 brake tubes from the brake tube way, and then disconnect the 2 brake tubes from the brake master cylinder. The process of removing the brake master cylinder starts by removing its two mounting nuts for ABS-equipped vehicles. The process to detach the brake master cylinder requires removing 2 nuts and the brake tube way when the vehicle does not have ABS. The O-ring should be removed from the brake master cylinder as the last step.

Slide the clip and remove the clutch reservoir tube.

Fill the reservoir with brake fluid, bleed the master cylinder and brake line, check the fluid level in the reservoir, and inspect for brake fluid leakage.

Inspect and adjust the brake booster push rod by setting Special Service Tool: 09737-00013 on the master cylinder sub-assembly and lowering the rod until it just touches the piston.

Connect the brake fluid level warning switch connector.
