9.12. Adjustments of a pedal of a foot brake


Adjusting parameters of a pedal of a foot brake

And — Size of a free wheeling of a pedal
D — Height of provision of the squeezed-out pedal
N — Height of provision of the released pedal

With 1 — the Gap of the sensor switch of stoplights
With 2 — the Gap of the sensor switch of a tempostat


Free wheeling of a pedal

The size of a free wheeling of a pedal of a foot brake "And" (see an illustration Adjusting parameters of a pedal of a foot brake) has to make 4 — 12 mm.

 PERFORMANCE ORDER

  1. In case of need release a lock-nut and make necessary adjustment by rotation of a rod of a pusher of the vacuum amplifier of brakes around a cutting finger. Having achieved the required result, tighten a lock-nut with the required effort (12 — 15 Nanometers). Check serviceability of shutdown of stoplights at a pedal otpuskaniye.


Reserve course of a pedal

 PERFORMANCE ORDER

  1. At the started engine ask the assistant to squeeze out a pedal with effort about 49 kgfs and measure height of provision of a block of the squeezed-out pedal from a floor — do not forget to unbend a mat. At negative results of check drive away the car in a workshop of car service for performance of the corresponding adjustment.

Excessive lowering of a pedal can speak violation of adjustment of drum brake mechanisms of back wheels — try to cock and release the parking brake several times.


Height of provision of a pedal

 PERFORMANCE ORDER

  1. Measure height of provision (D) pedal of the parking brake lowered (N) and squeezed out (see an illustration Adjusting parameters of a pedal of a foot brake). compare results of measurement to requirements of Specifications. In case of need release a lock-nut and make necessary adjustment by rotation of a rod of a pusher of the brake amplifier. Having finished, tighten a nut with the required effort (16 — 22 Nanometers) — track that the tip of a rod remained in a cutting finger of a pusher.
