Brake pressure switch - Harney hydraulic disc

[stemo76]

I have a 2000 Harney on a Magnum chassis. The master cyclinder started to leak and I ordered a replacement. The replacement didn't come with a new pressure switch so I removed the old one and it won't fit the new one. It might be because I bend bleed it before attempting to put the switch in.

Anybody have an experience with these master cylinders. This is a hydraulic setup with disc brakes, hydroboost. the pressure switch looks fake, it has no moving plunger and the two prongs for the connector appear to be connected.

this is all I can find on it. I tried blocking each line and bleeding it more to see if the valve will move, but nothing.

This is a long shot, but i have a 2000 Harney Magnum Chassis that needed a master cylinder for the brakes ( as well as all new disks and pads,. the truck shop where i took it claims the Cost for the Master cylinder is $3,800 can that be correct?

Any help with part numbers and parts dealers would be most appreciated

Maybe if it includes labor master cylinder and hydro boost still high but the job is done


Mine is the Bendix now Bosch
