Some driver friends, as well as the maintenance master who has not long entered the line, lack of understanding of the structure and design of the semi-trailer, maintenance and maintenance, and often do not know where to start when the trailer brake system fails.
Many faults on the trailer brake system are caused by the gas path, so today we will take a look at the common faults and solutions of the gas path of the trailer brake system:
The brake failure of semi-trailer generally occurs: air leakage, drag brake, brake failure, lock, etc., which are analyzed respectively below.
The air pressure is lower than 0.7MPa for a long time or there is an obvious drag brake phenomenon during the driving of the trailer.

Treatment method:
1.Check the air leakage source by applying soap and water, check the handshake connection, pipeline joint, emergency relay valve leakage, trailer ABS valve leakage phenomenon, brake chamber gas leakage and other possible faults.
2.Check whether the trailer valve body is flooded or can see obvious rust. If the phenomenon of air leakage still exists, it is necessary to check whether the valve body has water or can see obvious rust, which indicates that the trailer gas pipe filter, drying effect is not good, may need to replace the valve body.
The trailer has no brakes.
Treatment method:
1.When the main car is braking, if the trailer is not braking, you can check whether the trailer control pipeline has air pressure when the main car is braking. Check whether it is ventilated by pressing the check valve of the trailer brake control line handshake joint by hand.
2.If there is air pressure, the problem is the trailer brake valve on the trailer.
3.If there is no air pressure, the problem is the trailer brake control valve on the main vehicle.
Trailer can’t start after parking, keep holding.
Treatment method:
1, first remove the ABS helix (if equipped with ABS system), see whether it can start normally, to eliminate circuit problems. 2, make the tractor in the pumping state, pull out the air pipe of the hand control valve, check whether the air pressure of the air outlet is normal (the air pressure should be very large in the pumping state).
2.Check whether the parking brake is discharged.
3.If there is no problem with the gas path inspection, the mechanical failure of the axle should be checked eventually. Car Transport Trailer||Car Transport Trailers for rent|car transport trailer for rent|car transport trailer|Car Transport Trailer For Sale Uk
Brake lag:
When the driver presses the brake pedal to brake the vehicle, although the braking of the trailer is basically normal, the braking time of the trailer is obviously later than that of the main vehicle. Under the condition that the brake gap of each wheel of the trailer is normal, the main reason for the failure is that the brake valve of the trailer is out of order, resulting in the compressed air pressure of the brake valve output of the trailer is low, and the braking of the trailer is too lagging.
Treatment method:
1.Disassemble the trailer brake valve, clean the stains on the parts and replace the deformed parts, and then reinstall the trailer brake valve, adjust the adjusting screws on the brake valve, and measure that the trailer brake valve can steadily output 0.45Mpa compressed air.
2, if the output compressed air is greater than 0.45Mpa, the adjustment screw will be relaxed, on the contrary, if it is less than 0.45Mpa, the adjustment screw will be tightened, and then continue to measure the pressure value to ensure that the final pressure is normal.
