How to bleeding the Hydro boost brake booster?
BLEEDING THE HYDRO-BOOST Use only DOT-3 or better Brake Fluid in the brake master cylinder reservoir. 1. Fill power steering reservoir to the bottom of the filler neck with specified fluid. 2. Disable ignition system to keep the engine from starting and then crank the engine for several seconds. 3. Check fluid level and add fluid if needed.
How does a Hydro Boost steering system work?
Proper diagnosis of hydro-boost related problems requires an understanding of how the system works. A typical hydro-boost is shown in Figure 1. The hydro-boost is plumbed in line with the steering gear. The power steering pump supplies pressurized fluid for both the power steering gear and hydro-boost.
How to disconnect the Hydro Boost pushrod?
Disconnect the Hydro-Boost pushrod linkage from the brake pedal. NOTE: It may be necessary to remove the stoplight switch from the brake pedal. If so, unplug the stoplight switch wires, remove the hairpin retainer, slide the switch off the pedal pin just far enough to permit removing the switch from the pin. Do not damage the switch. 6.
How does a Hydroboost brake system work on a Winnebago?
A pressure relief valve vents accumulator to pump return port when pressure in accumulator exceeds approximately I600 psi. With brake return spring installed, brake pedal should return hard into rubber stop, and master cylinder and pedal rod lever should be at lull return. Install pre·assembled brake pedal rod assembly (rod, end and boot).

Where does the boost chamber go in a Winnebago?
Boost pressure chamber is vented through spool valve, to pump return port, and back to power steering pump. As brake pedal is depressed, it moves pedal rod and initiates movement of spool valve.
