Believe friends all know that often use cars in use process as long as a stop is bound to the hand brake.Because the driver leave the vehicle, if no use hand brake, the vehicle is likely to slide, in turn could cause an accident will happen.But must remind the general owners, actually hand brake is not universal insurance, because the handbrake efficiency will increase with frequency of use, and slow decline.Sometimes, obviously a parking brake have pull up, but because of brake system failure resulting in the accident.So the owner should be periodically for car hand brake for the proper maintenance and inspection.China control arm manufacturers and everyone together to share a handbrake normal maintenance inspection matters needing attention.
1.Determine the handbrake handle position.
Just like the foot brake pedal, parking brake handle has a pull on the process.Usually, when the handle is 70% of the lift to the whole trip, parking brake system should be in the normal brake position,So before the check handbrake of braking force, should first find out the working point of 70%, the working point can be determine by sound.Parked in a quiet place, and slowly pull the hand brake, pull the ratchet sound of number of sides, pulled up to the end of the handle.And then calculate the noise 70% position, this position is a handbrake lever of effective working point.
2.Check the handbrake organization efficiency.
Drove the rolls into the slope is bigger, the road is in good condition (preferably asphalt) slopes, stepping on the brakes, Hanging in the neutral position (if it is automatic transmission is hanging in the N block), Pull hand brake lever to the established working point position.Then loosen the brake pedal slowly, if the car without sliding, means that the hand brake performance is good.Uphill and downhill should do it again.
3.High speed do not use parking brake.
There are many owners that encountered brake failure, can pull the handbrake to slow down, in fact, that is very dangerous.Because the hand brake structure is not precise, and uneven distribution of braking force of the left and right sides, pull the parking brake at high speeds easily allows one side of rear-wheel antilock, prone to accidents launch x431 v+.The correct approach is through reduction gears to slow down, the speed is very low, pull the handbrake parking.
4.Check the handbrake sensitivity.
In addition to braking efficiency,, you should also check the sensitivity of the parking brake, the start of the slope is particularly important.In the absence of slope road slowly, and then shake handshandle brake handle, check the handle of the sensitivity.This checking method can make the handbrake structure wear, check the number of times shoulds not be too much.In the course of the inspection, if you find a handbrake braking efficiency or sensitivity is not ideal, usually you can adjust parking brake cable solution.The bottom of the hand brake lever and the joint of steel cable (generally covered by the inner decoration) has an adjustable structure autel maxisys ms906, loosen locking nut with a wrench, you can stretch the length of the brake cables.Some autos adjusting mechanism is located at the bottom of the car, if inconvenient adjustment, should by professional maintenance staff to deal with.
