Caused by the brake disc brake on back wheel should not have four kinds of spaces possible: First, the foot brake 5 exhaust inlets, high pressure gas instinct Pai people the atmosphere, caused by gas-liquid master cylinder should not spring back to place, cause the system Oil will move the brake disc brake wheel cylinder piston top dead can not come back to places; are gas-liquid two disc brake master cylinder to the tubing plug, resulting in brake wheel cylinder piston can not come back to places; are three master cylinder of gas-liquid Can not spring back to their own spaces, brake fluid under high pressure gas, liquid should not return to the master cylinder reservoir chamber, resulting in brake wheel cylinder piston can not come back to places; are four wheel disc brake piston brake system because of moving fluid dirty or rusty Pistons Can not Back-bit card dead.

造成盘式制动器上的制动分泵不能回位有4种可能：一是脚制动阀5的排气口堵塞，高压气体本能排人大气，造成气液总泵的弹簧不能回位，导致制动油将盘式制动器的制动分泵活塞顶死而不能回位；二是气液总泵至盘式制动器的油管堵塞，造成制动分泵活塞不能回位；三是气液总泵的弹簧本身不能回位，制动液在高压气体作用下，不能回到气液总泵的储油室，从而造成制动分泵活塞不能回位；四是盘式制动器制动分泵活塞由于制动液太脏或活塞生锈卡死而不能回位。

Caused by disc brake on the brake Wheel Cylinder could not return to places 4 possible: First, 5 foot brake valve exhaust port blocking, high-pressure gas instinct platoon atmosphere, caused by gas-liquid master cylinder of the spring could not return to place, resulting in the system move oil, brake disc brake Wheel Cylinder Piston top dead and could not return to places; second is to the disc brake master cylinder gas-liquid pipeline blockage, resulting in brake Cylinder piston can not return to place; third master cylinder of the gas-liquid Spring itself can not return to position, brake fluid under high pressure gas can not return Axial pump to gas-liquid master cylinder reservoir chamber, resulting in brake Cylinder piston can not return to places; Fourth Wheel Cylinder piston disc brake system, due to moving fluid dirty or rusty card dead and can not return to the piston position.

Brake is one of the most important components which ensure automobile run, and the clearance self-regulating device of brake is one of the most important parts of brake, but the study on the capabilities of clearance self-regulating device of discal brake is very little, especially the testing study on self- regulating device of discal brake is almost vacant.

汽车制动器是保证汽车安全行驶的重要部件，制动器间隙自调装置是制动器的一个重要部件，然而制动器的间隙自调装置性能研究在国内外比较少，特别是盘式制动器间隙自调装置检测的研究在国内还是空白。
