Too big course of a pedal of a brake:
– wrong adjustment of a pedal; – back brake shoes stand too far from a drum.
Low efficiency of braking:
– brake shoes, brake disks or drums are worn-out; – on brake disks (drums) brake fluid or oil got; – brake shoes do not nestle on brake drums (disks); – pollution of drum brakes oil; – the wrong type of brake shoes is used; – brake mechanisms are incorrectly assembled; – the vacuum amplifier of brakes does not work.
When braking the car takes away aside:
– on brake shoes on the one hand oil got; – partially or the working brake cylinder is completely jammed; – on the different parties brake shoes with different material of friction are used; – not coordinated brake disks; – uneven wear of tires of the car from the different parties; – there is an air at brake system.
Softness of a pedal when braking:
– new brake shoes were not completely earned extra; – bolts of fastening of the main brake cylinder are not clamped; – strong wear of brake drums.
By pressing a pedal of a brake against the stop brakes do not work:
– the leak in hydraulic system interfering transfer of pressure from the main brake cylinder to working brake cylinders; – consolidations of pistons of the main brake cylinder are worn-out.
The vacuum amplifier of brakes does not work:
– the vacuum hose is disconnected or is not tight; – the unilateral vacuum valve is faulty or incorrectly connected; – internal defect of the amplifier of brakes. |
