10.9. Possible malfunctions of brakes, their reasons and elimination methods

THE REASON
ELIMINATION METHOD
Insufficient efficiency of braking
Leak of a brake liquid from wheel cylinders of forward or back brakes Replace unusable details of wheel cylinders, wash out and dry колодки and drums, pump over hydrodrive system

Air in brake system

Remove air from system
Are damaged rubber уплотнители in the main brake cylinder Replace уплотнители and pump over system
Rubber hoses of a drive of brakes are damaged Check up the hoses, damaged replace
Incomplete растормаживание all wheels
There is no free wheeling of a pedal of a brake Adjust a pedal free wheeling
Contamination of a compensatory aperture in the main cylinder Clean an aperture and pump over a hydrodrive of brakes
Swelling of rubber sealants of the main cylinder owing to hit in a liquid of gasoline, mineral oils, etc. Carefully wash out all system a brake liquid, replace the damaged details, pump over hydrodrive system
Jamming of the piston of the main cylinder Check up and if necessary replace the main cylinder, pump over a drive of brakes
Притормаживание one of wheels at the released pedal of a brake
Ослабла or the coupling spring колодок brakes has broken Replace springs
Piston jamming in the wheel cylinder owing to corrosion or a contamination

Disassemble the cylinder. Clear and wash out the details, damaged replace

Swelling of sealing rings of the wheel cylinder because of hit in a liquid of combustive-lubricating materials

Replace rings, wash out a brake liquid system of a hydrodrive of brakes

There is no backlash between колодками and a drum

Adjust lay and back brakes

Infringement of position of a support concerning a brake disk owing to easing of bolts of its fastening to an arm

Tighten fastening bolts; if necessary replace the damaged details

The raised palpation of a brake disk (more than 0,15 mm) Прошлифуйте a disk if a thickness less than 9,0 mm – replace it
Drift or car withdrawal aside at braking
1. Leak of a brake liquid in one of wheel cylinders
Replace уплотнители and pump over system
Jamming of the piston of the wheel cylinder of brakes Check up and eliminate piston jamming in the cylinder, if necessary replace the damaged details

Закупоривание any steel tube owing to a dent or a contamination

Replace a tube or clean it and pump over system

Different pressure in tyres

Establish normal pressure

Wrong corners of installation of forward wheels

Adjust corners of installation of wheels

Pollution or замасливание disks, drums and overlays

Clear details of brake mechanisms

Wrong installation of a regulator of pressure Adjust position of a regulator of pressure
The pressure regulator is faulty Repair or replace a pressure regulator
The increased effort of pressing to a brake pedal
Swelling of sealants of cylinders because of hit in a liquid of gasoline, oils etc. Carefully wash out all system, replace the damaged rubber details; pump over system
Scratch or squeal of brakes
Easing of a coupling spring brake колодок a back brake Check up a coupling spring and if necessary replace new
Ovality of brake drums of back brakes Chisel drums
Замасливание frictional overlays

Smooth out overlays a metal brush, applying warm water with washing-up liquids. Eliminate the reasons of hit of a liquid or greasing on brake колодки

Deterioration of overlays or inclusion in them of foreign matters

Replace колодки

Excessive palpation of a brake disk or non-uniform deterioration Прошлифуйте a disk, at a thickness less than 9 mm – replace a disk in gathering with a nave of bearings of forward wheels
