Abstract
A tool for a brake system may comprise a tool body configured to fit within a recess of a body of the caliper assembly. The tool body comprises a first section; the first side comprises a raised surface; the second side comprises a base surface. The first section is to be inserted into the recess of the caliper assembly; in a first mode the first piston set is blocked by the raised surface and the second piston set is unblocked; in a second mode the second piston set is blocked by the raised surface and the first piston set is unblocked. The tool body comprises a second section to be inserted into the recess of the caliper assembly; in a third mode both the first piston set and the second piston set are blocked from movement. A brake system may comprise an improved master cylinder assembly.

A tool for use in a caliper assembly comprising a body with a first piston set and a second piston set and a recess comprising:
- a tool body comprising a first section;
- wherein the first section of the tool body is configured to fit within the recess of the body of the caliper assembly;
- wherein the first section of the tool body comprises a first side and a second side;
- wherein the first side of the first section of the tool body comprises a raised surface;
- wherein the second side of the first section of the tool body comprises a base surface;
- wherein the first section of the tool body is configured to provide a first mode of operation when inserted in the recess of the body of the caliper assembly with the raised surface of the first side of the first section configured to engage the first piston set;
- wherein the first section of the tool body is configured to provide a second mode of operation when inserted in the recess of the body of the caliper assembly with the raised surface of the first side of the first section configured to engage the second piston set;
- wherein the tool body is configured so that when inserted in the body of the caliper assembly for the first mode of operation the tool body cannot operate in the second mode of operation and when inserted in the body of the caliper assembly for the second mode of operation the tool body cannot operate in the first mode of operation.
A tool for use in a caliper assembly comprising a body with a first piston set and a second piston set and a recess comprising:
- a tool body configured to fit within the recess of the body of the caliper assembly;
- wherein the tool body comprises a first side and a second side;
- wherein the first side of the tool body comprises a raised surface;
- wherein the second side of the tool body comprises a base surface;
- wherein the tool body is configured to provide a first mode of operation when inserted in the recess of the body of the caliper assembly;
- wherein the tool body is configured to provide a second mode of operation when inserted in the recess of the body of the caliper assembly;
- wherein in the first mode of operation the first piston set is blocked by the raised surface of the first side of the tool body and the second piston set is unblocked by the tool body;
- wherein in the second mode of operation the second piston set is blocked by the raised surface of the first side of the tool body and the first piston set is unblocked by tool body;
- wherein the tool body is configured so that when inserted in the recess of the body of the caliper assembly for the first mode of operation the tool body cannot operate in the second mode of operation and when inserted in the recess of the body of the caliper assembly for the second mode of operation the tool body cannot operate in the first mode of operation.
