Sleeve for disk brake caliper and disk brake fitted with such a sleeve

#The present invention relates to a sleeve for a disk brake caliper and a brake disk fitted with such a sleeve.

#A disk brake of the known type comprises a carrier fixed to a wheel hub of an automotive vehicle and a caliper slidably mounted in the carrier. The disk brake also comprises a first and a second lining or brake pad, capable of respectively cooperating with a first and a second face of a brake disk fixed in rotation to a wheel.

#A pad, known as the internal pad, bears against one end of a hydraulic piston slidably mounted in the caliper along an axis parallel to the axis of the brake disk when the brake is applied.

#Further features and advantages of the invention will appear from reading the following description of an embodiment of the invention, by way of illustrative and non-limiting example, and with reference to the accompanying figures in which:

#FIG. 1 shows a disk brake caliper fitted with a sleeve according to the invention,

#FIG. 2 is a sectional view of the disk brake disclosed in FIG. 1,

#FIG. 1 shows a disk brake caliper 1 comprising a sliding carrier 2 fitted with two plates, internal 3 and external 4, permitting the disk 5 fixed to a wheel to be clamped as disclosed above.

#In order to guide the sliding of the caliper relative to the pins 6 and 8 of the caliper 1, sleeves or “bushings” are arranged between the carrier 2 and each pin 6 or 8 as shown in FIG. 2.

#In said FIG. 2, a sleeve 9 associated with the pin 8 is shown in a sectional view thereof corresponding to the axis 2-2 of FIG. 1.
