Hydraulic disc brake lever assembly

An brake lever assembly, comprising:

• a housing;
• a master cylinder assembly disposed in the housing and comprising a master piston, the master cylinder assembly having an adjustable dead band;
• a lever connected to the housing and having a reach;
• wherein the lever is pivotable about a first pivot axis to adjust the reach, and the lever is pivotable about a second pivot axis to actuate the master piston.

An brake lever assembly, comprising:

• a housing having first and second pairs of opposing slots, wherein the first and second pairs of opposing slots are spaced apart from one another;
• a lever having a first pivot shaft and a second pivot shaft, the first pivot shaft being disposed in the first pair of opposing slots and having a position in the first pair of slots, the second pivot shaft being disposed in the second pair of opposing slots;
• a master cylinder disposed in the housing;
• a master piston disposed in the master cylinder;
• a dead band adjustment device operatively connecting the master piston to the second pivot shaft, wherein the dead band adjustment device is adjustable to vary the position of the master piston with respect to the second pivot shaft;
• and
• a reach adjustment device connecting the housing to the first pivot shaft, wherein the reach adjustment device is adjustable to vary the position of the first pivot shaft in the first pair of opposing slots.

A brake lever assembly, comprising:

• a master cylinder assembly having a dead band and comprising a master piston disposed in a master cylinder;
• a lever operatively connected to the master piston;
• and
• means for adjusting the dead band.

A brake lever assembly, comprising:

• a housing having a pair of opposing slots;
• a master cylinder disposed in the housing and having a port;
• a master piston assembly disposed in the master cylinder, the master piston assembly comprising a master piston, the master piston having a seal, the master piston further having a non-actuated state defining a distance between the seal and the port when the master piston is in the non-actuated state;
• a lever having a first end and a cross member, wherein the first end is pivotally connected to the housing, and the cross member is spaced apart from the first end and disposed in the pair of opposing slots;
• and
• an adjustable connector operatively connecting the cross member to the master piston assembly, wherein the adjustable connector is adjustable to vary the distance.

A brake lever assembly, comprising:

• a housing;
• a master cylinder disposed in the housing, the master cylinder having a port;
• a master piston assembly disposed in the master cylinder, the master piston assembly comprising a master piston, the master piston having a seal and a non-actuated state;
• a lever pivotally connected to the housing, the lever having first and second forked portions and a space between the first and second forked portions;
• an adjustable connector disposed in the space and operatively connecting the lever to the master piston;
• wherein the seal and the port define a distance when the master piston is in the non-actuated state, and the adjustable connector is adjustable to vary the distance.
