In hereinafter, the present invention according to a preferred in one-application products on the accompanying drawing herein detailed feature is implemented pursuant to the embodiment aspects to less than 1000.

Prior to the present invention description number herein when the supplementary number as much as other form according dies along which caliper irradiation can be applied herein modified feature and techniques similar deformation range of water, including water to replacement will be understood to evenly.

Industrial field of application technology herein generally to indicate the number of charges to replace tank account for a caliper brake of an automobile, Figure 1 shows a generally being applied in an automotive vehicle brake caliper (100) structure by copper number inlet and the hydraulic movement lock piston (20) within a caliper housing (80) and, caliper housing and fastened to the vehicle body (80) through both ends of the guide rod slidably mounted carrier (70) on, carrier (70) your pad which is inside (30) match the pad (40) is inserted into a peripheral cutting edge while between which rotates with the wheel disk (90) structure is described in number technology background broadcast receiver.

Figure 2 shows a number which also 1 when said also to types of caliper (100) brake brake piston seal structure and the conditions of operation the position of the piston in order to compare a value indicative of the state of elastic deformation also in brake brake 2a, 2b was also indicate the operational status of the brake, 2c is applied within the caliper piston seal when knock back [Knock Back] for piston position of indicating a state of plastic deformation are disclosed.

Number ball of Figure 2 configuration which caliper (100) housing structure (80) of the main bore (81) into (82) is seal (83) extending injected into the inside of (84) of the housing through the main bore (81) is introduced into the oil injected into the oil seal (seal: 83) to the inside of (82) is expanded and a piston (20) pushes against your pad which is a (30) adapted to hold which, as it is also inputted with Piston 2a is output from the simultaneous brake brake brake (20) without the movement of Seal (83) is equal to normal position also in a circular state.

However is connected to actuate the main bore of the housing such as in fig. 2b (81) internal oil flowing from the pressure lifted Piston (20) pushing forward to me and, simultaneously Piston (20) is disposed on the side of the advancement Piston includes a front inner pad (30) is also pressed disc are attached, the seal (83) the piston (20) in the direction of the deformation at the time of state of plastic deformation is maintained so hear modified seal so generated brake brake multivalent (83) by a return force of paintings such as in-situ 2a to position engaged with each other.

Knock back phenomenon is also 2c case seal (83) position could be deformation of the chemical formula, so that the rotation of the brake disc upon rotation of said disc by run-out of a vehicle according to inertial force or inner pad (30) from the impact piston (20) the housing main bore (81) to the carrier is retracted towards the piston (20) upon retraction of seal (83) deformation shape of all the modified seal (83) is a withdrawal piston where it is partially prevented, a torsional force applied between the seal and piston seal restoring force or more sleep number invalid stroke and a restoring section includes a directional step appears to be their cause simultaneous increase causes a simultaneous increasing number is as a result of the substrate.

Figure 3 shows a ball number also herein which caliper (100) contour of the structure shows that the decomposition of the precursor is, caliper housing (80) and carrier (70) guide rod (84) and lockable to the bolt (72) and is fixed by means of, a caliper housing (80) interpolation into which piston (20) for effecting the sealing closure structure (21) of the piston (20) of the inner edge of a groove (20a) is closed making your pad which is fitted to the lowest (30) is of (20) housing with (80) applying outside carriers include fingers (60) match the pad (40) is arranged an additional copper number generated from the portion of the lung month stepping on a brake master cylinder hydraulic cylinder in order to, piston (20) with your pad which is (30) is moved forward in a rotary disk (90) into both ends of side of a hydraulic cylinder piston caliper housing by remaining momentarily (20) in the opposite direction while moving finger (60) is out pad (40) disk mill (90) can be produced by measuring the change of the power of the existing method the surface number is formed on the upper periphery of the new feature to be applied to the caliper basic configurations herein knock back [Knock Back] rpm to remove means for reducing Spring Knock back door number point (10) the Piston (20) of the housing main bore (81) between is a position at which (82) to spring (10) is installed Piston by force of an extension spring (20) is pushed than the normal operation position by preventing movement of the simultaneous number number (invalid stroke) empty lock applied simultaneous increase between brake caliper of improvement structure (100) indicating are disclosed.

Also in Figure 3 Figure 4 shows a like Piston (82) of main bore on Housing (81) for reducing knock back between the spring (10) installed on a rear side of the automobile turbo-(100) applied brake brake piston seal structure and the conditions of operation when the position of the piston in order to compare a value indicative of the state of elastic deformation also in brake brake 4a, 4b was also indicate the operational status of the brake, 4c knock back (Knock Back) is applied within the caliper piston seal piston when indicating a state of plastic deformation are disclosed.

Not Seal Piston differences in movement of pushing brake such as 4a also to maintain the shape of the existing method arrangement permits steady also be other configuration without also 2a are the same.

The oil pressure is applied to the housing main bore 4b housing feed port is increased and also brake operation of pushing forward and removed from the piston, the piston disposed includes a front piston advancement if the pad is also pressed disc are attached, the piston seal is a state of plastic deformation at the time of deformation in the direction of the generated brake so is maintained when modified seal also 2b are moved vertically by the restoring capability of prior art brake multivalent such as engaged position are disclosed.

Case 4c knock back phenomenon is also incorporated in the chemical formula deformation of seal position, so that the rotation of a vehicle brake according to inertial force upon rotation of said piston housing main bore toward the impact pad or disc disc by run-out of the piston to the retracted shape of seal carrier is retracted when the piston deformation when the elastic force of the spring to prevent a withdrawal of newly installed using unique spring retracted to prevent parallel piston seal deformation a file number to prevent invalid stroke number is decided by a simultaneous increase living together to maintain stable number billion between SUMMARY of the reactive functions in a reduction of stroke is under or over.

Herein functions with caliper's inconvenient when subjected to feature may be account for, the seal piston shrinks (Roll back) in Figure 5 and a reverse variation of pad and disc correlation of the drawing is supported by a piston seal between the piston moves forward in position are described stabilizers, 5a also comprises a brake brake piston position and seal shape indicating normal position which simultaneous, is due to internal hydraulic piston and pad product is also 5b housing upon actuation moves the piston seal and pushed to the disk stand is pushed towards the form which has been modified by indicating beam, 5c while the pad (pad) is moved vertically upon actuation comprises a brake is also out of the seal by a return force of the piston in which the situ pad spaced from the port in a state which permits the arrow direction indicates, according to a structure of a rotation-periodically so also comprises a brake 5d in disc run-out - the impact pad by a first step of inertial force or disc pad (pad) while inclining toward the revolution of the piston is piston seal (seal) and also pushed together is exposed and then drawing the situation occurs where the developing stipend hundred progressed into revealing the secret key, 5e also includes a piston seal 5d on a deformation of the seal again in restoration of amount which not polarized beam to support the arrow direction stipend hundred developing progress, is greater than a seal 5d also 5f also shrinks in a piston force acting as a result seal even after restoration of amount decreasing in the arrow direction and the outer periphery (pad) in a gap between the pad and the rotor as also 5a 5d Disk auditory canal gap difference representing the normal position but also in expanded normal position shaft to a gap between the pad and 5f Disk difference in number by which affects the difference between pad Disc on simultaneous change of a phenomenon of drawing contains invalid storke is increased to result are disclosed.

Figure 6 shows a caliper which also herein co number (100) structure hydraulic supply nine (13) Piston inside is a position at which (82) of main bore on Housing (81) between which a hydraulic supply projection (13a) that are provided with a projection (13a) for reducing knock back to spring (10) on one side of this protrusion (13a) structure which is fitted with structure improvement structure surrounding periphery of caliper of (100) structure may be applied in the chemical formula, herein the hydraulic Piston Housing main bore portions for reducing knock back between the spring (10) is installed in the hydraulic formation Piston arrangement permits vertical concave groove inside as well as applying a wafer are disclosed.

Or more descriptions herein through embedded portions for reducing knock back for brake caliper Piston Housing main bore compresses the spring installed between relief valve using the Piston Housing than the normal operation position by preventing movement of the simultaneous number pushed towards brake number between simultaneous (invalid stroke) adapted to prevent an increase in drawing number herein there is in addition characterized in that configuration which can be modified in various forms applied more convenience for the operation described will.
