Air disc brake noise and brake fluid problem solving method
Air disc brakes emit noise when braking, what is the reason? How to solve this problem? How to solve the problem of brake fluid in air disc brakes? The following is a small series for everyone to talk about air disk brake noise and brake fluid problem solving methods, I hope to help everyone.
Air disc brake noise problem solving method
When braking, if there is noise of “gazhi, gazhi”, the following methods can be used to eliminate:
1. An anti-noise piece is added between the air disc brake caliper piston and the brake lining to form an inclination on the piston. Therefore, the brake pad and the brake disc are in flexible contact during braking, so that the brake pad has no abnormal noise in the normal wear state.
2. Select the brake pad material with softer material and lower density.
3. When braking, the brake pad moves to one side, and a crash sound may occur. This is due to the excessive gap between the brake pad and the caliper body, and the gap can be eliminated by plating the solder. However, it should be noted that the solder should be plated on the side opposite to the direction of travel to prevent failure under the action of the braking force.
Air disc brake brake fluid problem solving method
Vegetable oil brake fluids do not meet the requirements of air disc brakes, so high boiling synthetic brake fluids must be used. However, the synthetic brake fluid has water absorbing properties. In some conditions of use, the boiling point drops rapidly. In order to prevent a significant drop in the boiling point of the brake fluid, the following measures are generally used:
1. Change the brake fluid regularly. In the summer of 3 months or driving smarttags "/> 5000km; after 6 months in winter or 1000km driving, the brake fluid will be updated.
2. Brake fluids of different natures are not interchangeable or mixed.
3. Seal the brake fluid. To limit the temperature rise of the brake fluid, ensure that the piston can be flexibly and automatically returned to avoid slipping or biting the brake due to rust and hairpin. When the brake pad wears too much, the amount of heat transferred to the brake fluid increases rapidly. Therefore, the worn brake pads should be replaced in time.
The above is about the air disk brake noise and brake fluid problem solution. I hope everyone can understand the air disk brake noise and brake fluid problem solution, it will help everyone.
