Abstract
A caliper for use in a disk brake system where a sufficient amount of grease exists at least in a space formed between a groove for setting a piston seal provided on the inside surface of the caliper body and a piston seal to be set therein, in a space formed between the outer surface of dust boots and said caliper body, and in a space formed by the dust boots, the caliper body, the piston and the piston seal; and a wheel cylinder for use in a drum brake system where a sufficient amount of grease exists at least in a space formed between a piston and a cup seal and in a space formed by the piston, a cylinder body and dust boots.
Claims11
A caliper for use in a disk type brake system comprising at least a caliper body having a cylinder portion, a piston, a piston seal, and dust boots;
- said caliper body comprising a first groove for setting said piston seal and a second groove for setting said dust boots, and said piston comprising a third groove for setting said dust boots,
- wherein a sufficient amount of grease exists in a space formed by said first groove for setting said piston seal and said piston seal attached around said piston, in a space formed by an outer side surface of said dust boots and said second groove formed in said caliper body, in a space formed by an inner side surface of said dust boots and said third groove formed in said piston, and in a space formed by said dust boots, said caliper body, said piston and said piston seal.
A method for assembling a caliper for use in a disk type brake system, which comprises at least a caliper body, a cylinder, a piston, a piston seal, and dust boots, comprising the following steps when said piston is put into said caliper body:
- a) applying grease to almost a half section of an outer surface of said piston from an inserting end;
- b) pressing the piston having grease on the half section thereof into said caliper body;
- thereby making said grease exist in a space formed by said dust boots, said caliper body, said piston and said piston seal.
A wheel cylinder for use in a drum type brake system at least comprising a cylinder body, a piston, a cup seal being provided between said cylinder body and said piston, and dust boots for covering said cylinder body and said piston, wherein a sufficient amount of grease exists at least in a space formed between said piston and said cup seal, and in a space formed by said piston, said cylinder body, and said dust boots.
