Distribution valve — removal and installation (Honda Accord 3)

The dual circuit brake control valve performs two functions. It distributes pressurized brake fluid from the master cylinder to the diagonal brake circuits (left front/right rear and right front/left rear), and reduces the fluid pressure to the rear brakes during heavy braking, preventing wheel lockup.

The control valve is not repairable. It rarely breaks, so before replacing this valve, first check all other possible causes of brake failure.

The valve is located either on the right fender or directly under the master cylinder. Before removing the valve, mark the position of each brake line on the valve. Carefully remove the lines from the valve and plug them immediately. Unscrew the valve from the mount. When reassembling, securely fasten the valve. Screw each line to the corresponding valve ports by hand, then tighten the connections to 15 Nm with a spanner. Do not overtighten the connections.
