Repair ZIL-5301

The signaling device is designed to warn the driver about damage to one of the circuits of the hydraulic drive brake system

ZIL vehicles and their modifications are equipped with a mechanical five-speed gearbox with synchronizers (Fig. 1).

The main brake cylinders (MBC) are connected by two bolts into one unit with pneumatic chambers, which are pneumatic boosters, and are installed on brackets on the front panel of the cabin under the hood of the car for braking the front axle wheels and behind the rear axle for the rear axle wheels

After repairing the crankshaft, as well as the flywheel, clutch or pulley installed on it, they must be balanced

To disconnect the rear axle without springs, the car must be placed on a flat horizontal platform or on an inspection ditch equipped with a lifting device

Disassembling the pneumatic hydraulic booster (PGU) for repairs is usually done in the following cases: fluid leaks through cuffs 29, 33, due to their swelling when using low-quality fluids; when the cuff of the pneumatic piston 23 wears out.
The probability of failure of other parts is small
