Purpose/Function
With the adoption of the master cylinder having an enlarged diameter (20.64 mm {0.8126 in}), brake pedal operability has been improved.
For vehicles with DSC, the diameter of the pipe between the master cylinder and the DSC HU/CM has been increased, improving response during DSC operation.
Construction
Except for the cap and brake fluid reserve tank, the master cylinder cannot be disassembled. Therefore, if there is any malfunction in the interior of the master cylinder, replace the cylinder component without disassembling.

Operation
When the brake pedal is depressed, the push rod of the power brake unit presses in the master cylinder piston. By pressing in the piston, pressure is applied to the brake fluid to operate the brakes.
