How to adjust the brakes of the truck? What is the truck brake adjustment tutorial?

Loosen back to 180 degrees after tightening, and pay attention to the homing situation of each adjustment arm.

The analysis is as follows: It depends on whether the car you are driving is a cut-off brake (the cut-off brake is the kind of brake cylinder that will burst if the air pressure is lower than 4) or a foot brake (not a cut-off. You need to apply the foot brake to stop).

If it is an air brake. First of all, the air pressure of the car should be increased to more than 5. Before you can release the hand brake (there is a special hand control valve in the cab) Before starting to drive, you must see that the air pressure is more than 6 before driving.

Otherwise, stepping on the two-foot brake will cause it to be difficult to start the car. If you turn off the air brake, it is best to put the piggy bucket safety valve.

It is better to adjust to 9 air pressure to automatically exhaust so as not to have enough air pressure.

Foot brakes are less of a hassle. Wait until the air pressure rises to 4 or more, and you can drive.

First tighten the screws in the opposite direction, and then loosen the three buckles in the direction, when loose, the driver should feel that if the braking effect is still not good, it is best to maintain it, change the brake pads.

Brakes are important.

Ordinary air brake system.

and the shut-off brake system, the two have similarities, but there are also differences. The main differences are as follows.

1) Parking brake.

There is an essential difference, the former is a first-class disc brake, which is a manpower type, and the latter is an energy storage spring gas brake, which is a power type, and its energy supply device is completely different.

2) The parking brake of ordinary air brake can only be used when the car is stationary, because its braking torque acts on the propeller shaft.

If it is used in the driving of the car, it is easy to cause serious overload of the drive shaft and rear axle, and it may also be due to the differential.

The shell is locked and the rotation direction of the left and right wheels is opposite, causing the car to deviate or even turn around when braking.

However, the energy storage spring brake is not, on the contrary, because the energy storage spring parking brake stroke is greater than the driving brake stroke, in the case of insufficient driving braking force, the energy storage spring can also be used to assist emergency braking. Therefore, the energy storage spring brake can not only be used as a parking brake, but also as an emergency brake. Therefore, compared with ordinary air brakes, the shut-off brake braking system is better in terms of braking stability and safety.

Explanation of the shut-off brake in layman's terms: there is a strong spring in the brake chamber, and the compressed air pushes up the spring when driving. Handbrake.

The car just let the gas out and let the springs lock the brakes. When the air pressure is too low during driving, it will also produce a braking effect to ensure safety.

Conventional braking is the handbrake locks the propeller shaft, and the foot brake locks the wheels by compressed air entering the brake chamber. In the event of mechanical failure of the handbrake or propeller shaft, the handbrake fails; When any part of the air pump, pipeline, air reservoir and brake valve fails, the foot brake fails. The shut-off brake can effectively avoid these dangers.

1. Some trucks do not need to be adjusted by hand when braking.

2. Without self-adjustment, the adjustment position is behind the tire, that is, the position blocked by a rubber plug on the brake wheel drum. Jack up the tires, Isuzu has two sub-cylinders for one tire, and there are arrows next to the holes, and they are tight in the direction of the arrows. There are two brake cylinders in each hub, and one wheel needs to be adjusted twice.

When adjusting, you should push up the adjustment wheel, and then adjust the wheel to lock it in the direction of the arrow, and then ** little by little, until the tire is just turned without a sense of resistance, and it is generally about three bars.

There is also the adjustment position on that side, a wheel only needs to be adjusted once, generally upward, is tightened, lowered or loosened, the wheel adjustment is locked, and then little by little, until the tire is rotated just without a sense of resistance.

3. Then there is the air brake car, there is a round air separation pump next to the tire, there is a 17 or screw on it, the front is clockwise tight, and the rear wheel is clockwise tight and counterclockwise is tight.

The brake light switches are on top of the foot pedals.

1. There are two kinds of brakes in modern cars, the first is the clamp brake, if the brake effect is not very good, the inner pump of the clamp brake pump of this wheel can see the counterclockwise rotation of a capped oil drain screw, and then tighten it after a few seconds, and then step on the brake pedal after repeatedly stepping on the brake pedal in the cab, at this time, the oil drain screw is unscrewed and then put a few seconds of oil in tightening, after repeating this process, the purpose of adjusting the brake is completed.

2. The second is the drum brake, there is a square empty space on the drum brake to adjust the wheel is used to adjust the brake, use two screwdrivers to dial the spring, and the other to dial the gear, but this method of adjusting the brake must cover the brake drum cover.

The truck brake adjustment tutorial is as follows:

<>5. Twist the adjusting screw counterclockwise to the right to loosen the brake.

<>2. When adjusting the brake, the screw in front controls the direction of rotation of the brake arm of the brake.

3. After that, use a wrench to adjust the brake screw.

4. Twist the adjustment screw clockwise to the right to tighten the brake.

<>5. Twist the adjusting screw counterclockwise to the right to loosen the brake.

Summary. <>2. When adjusting the brake, the screw in front controls the direction of rotation of the brake arm of the brake.

3. After that, use a wrench to adjust the brake screw.

4. Twist the adjustment screw clockwise to the right to tighten the brake.

<>5. Twist the adjusting screw counterclockwise to the right to loosen the brake.

How to adjust the tightening diagram of the front brake of the truck.

1. First find the brake adjustment screw on the front wheel axle, as shown in the figure. <>2. When adjusting the brake, the screw in front controls the direction of rotation of the brake arm of the brake. 3. After that, use a wrench to adjust the brake screw.

4. Twist the adjustment screw clockwise to the right to tighten the brake. <>5. Twist the adjusting screw counterclockwise to the right to loosen the brake.
