<p>PURPOSE: To prevent deterioration of brake properties for a long time by reliably preventing the slide resistance of a guide arm of a caliper to a cylindrical member from being increased in a slide mechanism of a pin slide-type disc brake. CONSTITUTION: In a pin slide-type disc brake in which a small-diameter hole is provided on the end of one guide arm 20, and this small-diameter hole is blocked by fitting a plug 54 for aspiration to the small-diameter hole. An annular groove is formed on the tip outer periphery of a slide pin 26 for supporting one guide arm 20, an U-shaped packing 60 is fitted into this annular groove, and the slide surfaces of the guide arm 20 and the slide pin 26 are sealed.</p> |
