6.1.8. Troubleshooting at unilateral wear of a brake shoe

Unscrew the flowing union on one of forward brake supports. Connect the manometer of a tester of the brake system.
Start the engine.

Modeling of various braking with a pressure прибл. 100 bars
Slowly press a brake pedal for achievement of various pressure.
Quickly press a brake pedal for achievement of various pressure.
Once with a force press on a brake pedal.
If the wheel is turned hardly and in the brake system there is no residual pressure,
the hard course or pollution of a brake shoe in a guide of a brake support is possible.
Jamming or hard piston stroke in a brake support is possible.
If the wheel is turned hardly and in the brake system there is residual pressure, the hard course of pedal knot or hit of a foreign matter in a mechanical part of pedal knot is possible.
If the pedal of a brake is possible to delay a little back and brake pressure reduces to zero, then the amplifier of the brake drive is subject to replacement or the hard course of pedal knot takes place.
