Splitscreen Bus Dual Circuit Master Cylinder Conversion Bundle Kit

Upgrade your single circuit brake system to dual circuit with this kit.

For up to 1966 and 1967 euro spec non servo brakes with a dual master cylinder:

The rear brake line and brake light switch are fitted to the front two ports closest to the push rod.

You should have two front brake lines, one to each of the left and right front brakes. These fit to the two rear ports on the dual circuit cylinder.

For 1967 US buses non servo brakes with a dual master cylinder:

The rear line is fitted to one of the front ports closest to the pushrod. The front line is fitted to one of the rear ports. There are 2 brake light switches one in the front port and one in the rear port.

Check the rod that goes into the master cylinder from the pedal. It should have an 1/8 inch of play before, you can feel the rod make contact with the plunger

If there is no play – the plunger will not come back far enough to let the fluid into the cylinder.

If it has too much play – you will be pushing the pedal down a long way before the master cylinder even does anything.

To adjust undo the jam nut on the pushrod and change the length, then do the nut back up.

Tips: If you are changing you master cylinder, some or all of the brake pipes may need to be re-routed. This is due to the port layout being different on the new master cylinder. When planning your brake line routing, be sure to fit the brake switch `below` the master cylinder centre line. Otherwise air can be trapped in the system which will make it difficult to bleed the brakes.

It is also VERY important that the end play of the brake pedal pushrod is adjusted correctly. Follow the factory specifications of 1mm endplay. The pushrod can be adjusted using the thread and lock-nut on the pushrod shaft. For some applications you may have to cut the pushrod down in length.
