Description

Quick simple and easy dismouting brake block instrument

Technical Field

The utility model relates to an automobile brake pad frock especially relates to a quick simple and easy dismouting brake pad instrument.

Background

The disc brake caliper of general automobile mainly includes a caliper cylinder body, a piston, an oil seal, a brake block group located on two sides of brake disc, when a brake master cylinder produces a brake oil pressure, the brake oil can flow into the oil chamber via the oil inlet of the brake caliper to push the piston to press a brake block adjacent to the piston, when the brake block is pressed against the surface of the brake disc, the caliper cylinder body can move towards another brake block due to the reaction force, until the brake block is pressed against the other surface of the brake disc, the brake block group can clamp the disc surfaces on two sides of the brake disc to produce the brake effect.

However, the brake pad is a member with a predetermined thickness made of a material with wear resistance and high friction coefficient, and the brake pad is worn to a certain thickness or less gradually after being used for a period of time, so that the brake pad needs to be replaced to maintain the braking force to ensure the driving safety; however, as the thickness of the brake pad is gradually reduced along with the wear of the brake pad, the piston moves forward and protrudes out of the oil chamber due to the principle action of the one-way valve, so that the space for accommodating the brake pad in the brake caliper is reduced, therefore, when a new brake pad is to be replaced, the piston must be pushed back to the original position to smoothly install the new brake pad in the brake caliper, but the piston must be pushed to reset, and the oil pressure in the oil chamber must be overcome, so that the piston cannot be pushed to reset in a bare-handed manner directly, so that a tool for pushing the piston is generally used for pushing the piston to reset by a hand tool such as a wrench or a straight screwdriver, but the space for operation is limited, so that the force application degree is difficult to grasp, the piston is often damaged due to excessive force application, the piston also needs to be replaced, therefore, the pushing of the piston by the general hand tool cannot be operated quickly, and the piston is easily damaged.

In summary, the disadvantages of the prior art are overcome, and the conventional auxiliary tool for replacing the brake pad of the disc brake caliper is basically configured to push the piston by using a hand tool such as a general wrench or a straight screwdriver, which is inconvenient to operate and is easy to damage the piston due to excessive force application; the existing replacing tool for the brake pad is complex in structure and complex in use process, the space for accommodating the brake pad is very narrow when a part of pistons of a vehicle type advance and protrude out of an oil chamber, the existing common tool cannot be placed in the existing replacing tool, and a special replacing tool for the vehicle type is required, so that the replacing tool is very inconvenient; in view of solving the above disadvantages, the present invention provides a tool for quickly and easily assembling and disassembling a brake pad.
