Pedal height in the released situation
Check
Measure distance from the central part of a block of the released pedal to a partition of an impellent compartment. If the result of measurement falls outside the limits an admissible range (see. Specifications of Head Brake system), make the corresponding adjustment.

Disconnect electroconducting from the sensor switch of stoplights (And).
Release a lock-nut (In) and, rotating the sensor switch (And), take away it a plunzher from the pedal lever.
Release a lock-nut (D) and, rotating a rod of a pusher (D), adjust height of provision of the released pedal.
Adjust size of a free wheeling of a pedal (see below), then tighten a lock-nut (D) with demanded effort (23.5 ÷ 34.3 Nanometer).
Rotating the sensor switch of stoplights (And), achieve, that its plunzher easily nestled on the pedal lever. Tighten with demanded effort (13.7 ÷ 17.7 Nanometer) a lock-nut (In).
Make sure of serviceability of operation of stoplights already at easy squeezing of a pedal of a foot brake, - at a pedal otpuskaniye stoplights should be disconnected unequivocally.

Several times squeeze out a pedal of a foot brake for the purpose of dumping of residual depression in the vacuum amplifier.
Slightly pressing a pedal hand fingers, measure course size till resistance emergence. If the result of measurement falls outside the limits an admissible range (4-7 mm), make the corresponding adjustment.

Release a lock-nut (D) and make the corresponding adjustment by rotation of a rod of a pusher (And).
Tighten a lock-nut with demanded effort.

Pedal height in the squeezed-out situation
|
|
Squeeze out a pedal with effort of 69 kgfs and measure height of its situation over the floor panel. If the result of measurement makes less than 117 mm, pump over a hydraulic path of brake system (see. Section Pumping of brakes). If pumping of brakes does not lead to situation correction, check a condition of automatic regulators of drum-type brake mechanisms of back wheels (see. Section Service of drum-type brake mechanisms of back wheels).
