Diagnostic table

State

Possible reason

Elimination

Insufficient brake effort

Leak of brake fluid from brake highways

Find the place leak and eliminate

Clear or replace

Brakes are overheated

Define the reason and repair

Bad contact of blocks with the brake drum

Repair that there was a necessary contact

Spots of liquid or water on overlays of brake shoes

Replace

Strongly worn-out overlays of brake shoes of a slip

Replace

ABS if the car is equipped with it is faulty

Check system and replace if necessary

The excess course of a pedal (the course of a pedal is too big)

Partial failure of the brake system

Check brake systems and repair if necessary.

There is not enough liquid in tanks of the main cylinder

Fill tanks with the recommended brake fluid. Check for leak and availability of air in brake systems. Check the warning lamp. Pit air from system if it is required

Air in system. ("soft" pedal)

Pit air from system
