11.2. Checks and adjustments of a pedal of a foot brake
Checks of a pedal of a foot brake
Pedal height in the released situation
Check
Measure distance from the central part of a block of the released pedal to a partition of a motive compartment. If the result of measurement exceeds the limit of admissible range (see Specifications of the Head the Brake system), make the corresponding adjustment.
Adjustment
|
|
- Disconnect an electrical wiring from the sensor switch of stoplights (And).
- Release a lock-nut (V) and, rotating the sensor switch (A), take away its plunger 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 the size of a free wheeling of a pedal (see below), then tighten a lock-nut (D) with the required effort (23.5 ÷ 34.3 Nanometers).
- Rotating the sensor switch of stoplights (A), achieve that its plunger easily nestled on the pedal lever. Tighten with the required effort (13.7 ÷ 17.7 Nanometers) 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 have to be disconnected unambiguously.

Size of a free wheeling of a pedal
Check
|
|
- 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 until emergence of resistance. If the result of measurement exceeds the limit of the 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 the required 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 the brake system (see the Section Pumping of Brakes). If pumping of brakes does not lead to correction of a situation, check a condition of automatic regulators of drum brake mechanisms of back wheels (see the Section Service of Drum Brake Mechanisms of Back Wheels).
