The common faults of hydraulic brake made brake bite

     Made brake bite

    1.The phenomenon: the car, use once or several times after the brake, vehicle starting and accelerating the difficulties, the carmust

Mileage, brake drum has a fever.

    2.Reason:

   (1) The brake pedal free travel.

   (2) The gap between the brake drum and the brake shoe is too small, the brake shoe return spring break or fatigue over blowing.

   (3) The brake fluid is too dirty or precision is too large, so thatthe oil return difficult.

   (4) General pump bypass holes to plug the hole back; the totalpump or pump leather or leather ring aging, deformation, swell.

   (5) General pump piston return spring is too soft or broken or piston seizure.

Electromagnetic Clutches And Brakes

   3.Fault diagnosis and troubleshooting:

    According to the fault phenomena is the whole car to bite or individual to bite, and then further diagnosis.

    (1).If the whole car made brake bite:

   1) check the brake pedalhas no free travel. 

    2) open the liquid storage chamber cover,"even set foot"

    Methods to observe the brake pedal, oil. If the oil return slow or no oil return, should check the brake fluid is dirty or viscosity is too large. If the brake fluid purity, then step on the brake,release the brake pedal, and loosen any pump gas ejected bolt,brake fluid, the whole car made brake bite phenomenon lift.

     (2).If the individual wheels bite: 1) to support the made brake bite wheel, unscrew the pump exhaust bolt, if the brake fluidrush

     Speed after spraying brake shoe return, check the brake pipe is blocked. 2) liquid discharge, if the brake shoe still can notreverse, check the brake clearance is too small. 3) if the abovetests were normal, then check the pump piston, decomposition ofthe leather bowl and other cause brake shoe return bad factors.
