6.1.8. Troubleshooting at unilateral deterioration brake pads

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

Modelling of various braking at pressure прибл. 100 bar
Slowly press a pedal of a brake for achievement of various pressure.
Quickly press a pedal of a brake for achievement of various pressure.
Unitary with force press on a brake pedal.
If the wheel is turned hardly and in brake system there is no residual pressure,
The hard course or pollution brake pads in directing a brake support is possible.
Jamming or hard piston stroke in a brake support is possible.
If the wheel is turned hardly and in brake system there is a residual pressure, the hard course of pedal knot or foreign matter hit in a mechanical part of pedal knot is possible.
If the brake pedal manages to be delayed a little back and brake pressure reduces to zero, the amplifier of a brake drive is subject to replacement or the hard course of pedal knot takes place.
