7.5 - Cleaning Out Anti-lock Braking System ( )

Move the coolant tank out of the way after disconnecting the coolant level sensor. Then remove the electric pump and accumulator and set it aside after plugging both sides of the suction line (tank to pump) and removing the output line.

Remove the hose and heater for the pcv system for easy access.

Disconnect all the electrical connections.

Disconnect the 3 brake lines and plugged both sides.

Undo the 4 nuts that hold the master cyl. and power booster to the large aluminum mount.

Remove the rubber plugs that cover the linkage pin.

Remove clip and pin.

Separate the master cyl/ booster from the mounting.

Take the valve body apart and removed the solenoid valves(6 of them) after unsoldering the connections. They are mounted in the body using O rings. Just twist and pull using pliers.

The solenoid valves have pinhole orifices with screens over the in and out parts. Ports on the side and pin holes on the flat face.

Screen rings slide over the sides on all, and 3 have screens crimped onto the faces that can be pried out using an xacto knife. The other 3 have the face screens mounted in the valve body so no need to remove them.

Blow everything out with compressed air(screens, solenoids, valve body, lines...everything).

Test the solenoids, put about 10 volts on them and they should click.

Take the booster and master cylinder apart and clean these parts as well.

Reassemble (obviously!).
