Abstract

a pad liner for reducing drag in a brake caliper, provided in a vehicle brake which has a caliper receiving a portion of a brake disc rotating along with a wheel and pads installed so as to respectively press both surfaces of the brake disc when a brake pedal is operated in the caliper, the pad liner being installed in the caliper to provide elastic force such that the pads are spaced apart from the brake disc. The pad liner further includes elastic parts which obliquely extend from the pad liner and come into oblique contact with ends of the pads such that the pads are spaced apart from the brake disc when the operation of the brake pedal is completed.

First claim

What is claimed is:

1. A pad liner for reducing drag in a brake caliper for a vehicle brake, in which the vehicle brake includes: a caliper in which a portion of a brake disc rotates along with a wheel; and brake pads respectively pressing both surfaces of the brake disc when a brake pedal is operated in the caliper, the pad liner comprising elastic parts which obliquely extend from the pad liner and come into oblique contact with ends of the brake pads such that the brake pads are spaced apart from the brake disc when the operation of the brake pedal is completed,
wherein the pad liner is disposed inside the caliper and provides an elastic force such that the brake pads are spaced apart from the brake disc,
wherein the pad liner further comprises: a main body defining the entire portion of the pad liner; and extension parts extending downwardly from an upper end of the main body and spaced apart from the main body, wherein the elastic parts are surrounded by the extension parts,
wherein the pad liner further comprises a connection part connecting the upper end of the main body to upper ends of the extension parts,
wherein each of the extension parts is entirely spaced apart from the main body at a predetermined distance,
wherein each of the elastic parts is inclined from the associated extension part at a set angle, and
wherein each of the elastic parts is inclined away from the extension parts to be further spaced apart from the extension parts toward an inner side of the pad liner.

2. The pad liner of claim 1 , wherein the extension parts are connected to the end of the connection part in a width direction of the pad liner.

3. The pad liner of claim 1 , wherein each of the elastic parts is formed by cutting a U-groove in the extension parts in a width direction of the pad liner.

4. The pad liner of claim 3 , wherein the elastic part is formed by forming a U-groove at a middle portion of the extension part and obliquely bending a center portion thereof.

5. The pad liner of claim 1 , wherein the extension parts support side surfaces of the brake pads such that the brake pads are spaced apart from the brake disc when the extension parts press the side surfaces of the brake pads by a constant load.

6. The pad liner of claim 1 , wherein the main body has pad locking parts which are bent in a “U” form at a middle portion of the main body and are fixed to side surfaces of the brake pads.

7. The pad liner of claim 1 , wherein a lower portion of a space between the extension parts and the main body is opened.
