No. 12, A3, gucheng industrial park, longyao county, xingtai city, hebei province.A brake drum is a part of a drum-type braking system in which the pistons apply pressure on the two-and-a-half moon shoe to the inside of the tympanum, creating friction that stops the wheels spinning.
When the vehicle is running, the brake pedal cannot be applied immediately after it is pressed to the bottom. The braking effect is weak. The vehicle should continue to taxi and check the road surface. The reasons are as follows:
1, brake shoe friction plate too long use, wear serious, or mountain driving, brake use frequently, friction generated high temperature, friction plate surface layer ablative aging, not timely repair.
2, brake shoe friction plate in the riveting process, the quality is not good, rivets become loose and shake; Improper or not timely adjustment of brake clearance; Brake drum into sand grains or rivets fall off, causing the drum, sheet surface groove, poor contact, braking performance reduced.
3. The internal hole of the underwriting sleeve of brake shoes is big, which makes the shoes sink, and it is difficult to adjust the gap; Or brake shoe support adjustment CAM in the sleeve corrosion stuck, hinder the brake clearance adjustment, reduce the braking effect.
4, brake drum bearing nut adjustment is too loose or too tight. When the vehicle is too loose, the friction plate is in bad contact with the brake drum. When the bearing is too tight, the lubricating oil becomes thin and drips to the friction plate, causing skidding and soft braking fatigue.
5, the air compressor work is not good, so that the air storage cylinder air pressure is insufficient, brake pipeline leakage, brake valve sealing lax air leakage; Distributor pump skin bowl damaged; Air compressor series oil, so that a lot of oil, do not enter the brake pipeline, causing brake weakness.
6. Excessive free travel of the brake pedal; Brake drum and disc gap adjustment discomfort, brake drum out of circle; The worm on the brake arm is improperly adjusted, which makes the push rod of the brake pump extend too much, the balance spring of the composite brake valve blocks the hairpin, and the internal and external balance springs interfere with the movement during the braking.
