Abstract

A portable electronic brake tool includes a housing, a rechargeable battery removably inserted into the housing, a reverse polarity switch positioned at an exterior surface of the housing, a connector assembly that includes a wiring interface mounted in the housing and a wiring harness designed to detachably connect to an electric receptacle of an electronic brake caliper, and an electrical wiring assembly positioned in the housing and operatively connecting the rechargeable battery, the reverse polarity switch, and the wiring interface.

Claims (33)

1 . A portable electronic brake tool comprising:

a housing;

a rechargeable battery removably inserted into said housing;

a reverse polarity switch disposed at an exterior surface of said housing;

a connector assembly comprising a wiring interface mounted in said housing and a wiring harness configured to detachably connect to an electric receptacle of an electronic brake caliper; and

an electrical wiring assembly disposed in said housing and operatively connecting said rechargeable battery, said reverse polarity switch, and said wiring interface.

2 . The portable electronic brake tool of claim 1 , wherein said wiring harness comprises a cord and a plug.

3 . The portable electronic brake tool of claim 2 , wherein said connector assembly comprises a plurality of said wiring harnesses each comprising a different type of said plug configured to detachably connect to a different type of electric receptacle corresponding to an electronic brake caliper of different automobiles or groups of automobiles, wherein said wiring interface comprises a first connecting member projecting from said housing and each of said wiring harnesses comprises a second connecting member disposed at an end of said cord opposite said plug and configured to detachably connect with said first connecting member.

4 . The portable electronic brake tool of claim 1 , wherein said housing comprises a magnetic mounting structure configured to removably mount said housing on a metallic component of an automobile adjacent an electronic brake caliper.

5 . The portable electronic brake tool of claim 4 , wherein said magnetic mounting structure comprises two magnets disposed a distance apart and on one side of said housing.

6 . The portable electronic brake tool of claim 1 , wherein said housing has an elongated shape and is sufficiently small to be held by one hand of a user.

7 . The portable electronic brake tool of claim 1 , wherein said rechargeable battery comprises a 12-volt battery.

8 . The portable electronic brake tool of claim 1 , wherein said reverse polarity switch comprises a waterproof cover mounted at an exterior surface of said housing.

9 . A method of using a portable electronic brake tool comprising a housing; a rechargeable battery removably inserted into said housing; a reverse polarity switch disposed at an exterior surface of said housing; a connector assembly comprising a wiring interface mounted in said housing and a wiring harness configured to detachably connect to an electric receptacle of an electronic brake caliper; and an electrical wiring assembly disposed in said housing and operatively connecting said rechargeable battery, said reverse polarity switch, and said wiring interface; said method comprising the steps of:

disconnecting an electric receptacle of an electronic brake caliper from an electrical assembly of an automobile;

connecting the portable electronic brake tool by connecting said wiring harness of said connector assembly to the electric receptacle of the electronic brake caliper; and

engaging said reverse polarity switch to selectively advance or retract the piston of the electronic brake caliper.

10 . The method of claim 9 , wherein said wiring harness comprises a cord and a plug, and wherein said connector assembly comprises a plurality of said wiring harnesses each comprising a different type of said plug configured to detachably connect to a different type of electric receptacle corresponding to an electronic brake caliper of different automobiles or groups of automobiles, and wherein said wiring interface comprises a first connecting member projecting from said housing and each of said wiring harnesses comprises a second connecting member disposed at an end of said cord opposite said plug and configured to detachably connect with said first connecting member, and wherein said method further comprises:

selecting a first wiring harness comprising a first type of said plug and detachably connecting said first wiring harness to said wiring interface;

using the portable electronic brake tool with an electronic brake caliper having a first type of electric receptacle corresponding to said first type of said plug;

disconnecting said first wiring harness and selecting a second wiring harness comprising a second type of said plug and detachably connecting said second wiring harness to said wiring interface; and

using the portable electronic brake tool with another electronic brake caliper having a second type of electric receptacle corresponding to said second type of said plug.

11 . The method of claim 9 , wherein said housing comprises a magnetic mounting structure, and wherein said method further comprises magnetically removably mounting said housing on a metallic component of an automobile adjacent an electronic brake caliper.

12 . The method of claim 11 , wherein said step of magnetically removably mounting said housing comprises magnetically removably mounting said housing on a surface of a rotor of an automobile brake.

13 . A portable electronic brake tool comprising:

a housing, wherein:

said housing comprises a magnetic mounting structure configured to removably mount said housing on a metallic component of an automobile adjacent an electronic brake caliper, wherein said magnetic mounting structure comprises two magnets disposed a distance apart and on one side of said housing,

said housing has an elongated shape and is sufficiently small to be held by one hand of a user;

a rechargeable battery removably inserted into said housing, wherein said rechargeable battery comprises a 12-volt battery;

a reverse polarity switch disposed at an exterior surface of said housing, wherein said reverse polarity switch comprises a waterproof cover mounted at an exterior surface of said housing;

a connector assembly comprising a wiring interface mounted in said housing and a wiring harness configured to detachably connect to an electric receptacle of an electronic brake caliper, wherein said wiring harness comprises a cord and a plug; and

an electrical wiring assembly disposed in said housing and operatively connecting said rechargeable battery, said reverse polarity switch, and said wiring interface.

14 . The portable electronic brake tool of claim 13 , wherein said connector assembly comprises a plurality of said wiring harnesses each comprising a different type of said plug configured to detachably connect to a different type of electric receptacle corresponding to an electronic brake caliper of different automobiles or groups of automobiles, wherein said wiring interface comprises a first connecting member projecting from said housing and each of said wiring harnesses comprises a second connecting member disposed at an end of said cord opposite said plug and configured to detachably connect with said first connecting member.
