Claim 3

Hydraulic disc brake construction comprising: a caliper body member having a top surface and a side surface extending from one edge of said top surface; a fluid passage in said body; a cap member overlying at least a portion of said side surface; a fluid passage in said cap member; a fluid connector projecting between said body and cap members and providing fluid communication between the passage in said body and the passage in said cap member, said connector including an endless side wall having a rim projecting into said body member; a recess formed in the side surface of said body member and having an end wall defining a seat for said rim; a port communicating with the end wall of said recess and with said fluid passage in said body member, said port being smaller than said recess such that said seat is defined by the end wall of said recess surrounding said port; an endless elastomeric sealing member interposed between said rim and said seat; a cylindrical projection extending into said recess from said port, said rim and elastomeric member being received between said cylindrical projection and the side wall of said recess.

Claim 4

Hydraulic disc brake construction comprising: a caliper body member having a top surface and a side surface extending from one edge of said top surface; a fluid passage in said body; a cap member overlying at least a portion of said side surface; a fluid passage in said cap member; a fluid connector projecting between said body and cap members and providing fluid communication between the passage in said body and the passage in said cap member, said connector including an endless side wall having a rim projecting into said body member; a recess formed in the side surface of said body member and having an end wall defining a seat for said rim; a port communicating with the end wall of said recess and with said fluid passage in said body member, said port being smaller than said recess such that said seat is defined by the end wall of said recess surrounding said port; an endless elastomeric sealing member interposed between said rim and said seat; a cylindrical projection extending into said recess from said port, said rim and elastomeric member being received between said cylindrical projection and the side wall of said recess.

Claim 5

Hydraulic disc brake construction as claimed in claim 2 further including a resilient gasket received between said cap member and side surface; said gasket being cut away at its periphery to define a peripheral portion of reduced thickness; and a brake actuating component having a flange received between said reduced thickness portion and one of said end cap and caliper body.

Claim 6

Hydraulic disc brake construction as claimed in claim 3 wherein the flange of said component is of metal and is coated on at least one surface with elastomeric material.

Claim 7

Hydraulic disc brake construction as claimed in claim 2 wherein said connector has a loose fit relationship with said recess.

Claim 8

Hydraulic disc brake construction as claimed in claim 5 wherein said sealing member is bonded to said rim.

Claim 9

Hydraulic disc brake construction as claimed in claim 6 wherein said connector is threadedly mounted in said cap member.

Claim 10

Hydraulic disc brake construction as claimed in claim 7 wherein said connector includes a head portion with a cavity therein surrounded by said endless side wall, and a threaded shank portion extending from the end of said head portion opposite said rim.

Claim 11

Hydraulic disc brake construction as claimed in claim 8 including a passage through said shank portion communicating at one end with said cavity.

Claim 12

Hydraulic disc brake construction as claimed in claim 9 including a transverse port in said shank portion communicating with the passage in said cap member.

Claim 13

Hydraulic disc brake construction as claimed in claim 10 including an annular groove in said end cap sUrrounding said shank, and an elastomeric sealing member received in said groove and retained therein by said head portion.

Claim 14

Hydraulic disc brake construction as claimed in claim 11 wherein the passage in said shank portion is of noncircular cross-section.

Claim 15

Hydraulic disc brake construction as claimed in claim 2 wherein the endless side wall of said connector has a rim projecting into said cap member, and including means defining a seat in said cap member for said last named rim.

Claim 16

Hydraulic disc brake construction as claimed in claim 13 including a port surrounded by the seat in said caliper body and communicating with the passage in said caliper body, and a port surrounded by the seat in said cap member and communicating with the passage in said cap member.

Claim 17

Hydraulic disc brake construction as claimed in claim 14 including an endless elastomeric sealing member interposed between each rim and its associated seat.

Claim 18

Hydraulic disc brake construction as claimed in claim 15 wherein a recess is formed in said side surface and a recess is formed in said cap member, the port in said caliper body communicating with the end wall of the recess in said side surface and the port in said cap member communicating with the end wall of the recess in said cap member, said recesses being of larger cross-section than the respective ports, and said seats are defined by the end walls of the recesses surrounding the respective ports.

Claim 19

Hydraulic disc brake construction as claimed in claim 16 further including a cylindrical projection extending into each recess from the respective ports, said rims and elastomeric members being received between the respective cylindrical projections and side walls of said recesses.

Claim 20

Hydraulic disc brake construction as claimed in claim 17 wherein said connector has a loose fit relationship with said recesses.

Claim 21

Hydraulic disc brake construction as claimed in claim 18 wherein each sealing member is bonded to the respective rim of said connector.

Claim 22

Hydraulic disc brake construction as claimed in claim 19 further including a resilient gasket received between said cap member and side surface; said gasket being cut away at its periphery to define a peripheral portion of reduced thickness; and a brake actuating component having a flange received between said reduced thickness portion and one of said end cap and main body.

Claim 23

Hydraulic disc brake construction as claimed in claim 20 wherein the flange of said component is of metal and is coated on at least one surface with elastomeric material.
