Brake with two discs of fixed spacing

The present invention relates to a disc brake for a motor vehicle, comprising an inner (12) and an outer (14) disc, fastened one to the other and with a fixed spacing (D), an outer pair and an inner pair of friction elements for coming into frictional engagement with the opposite faces of the two discs, and support (16) and control (42, 42') members intended for laying the friction elements against their respective disc, the brake comprising a supporting yoke (16) extending both on the inside of the inner disc (12), in the gap (D) between the two discs, and on the outside of the outer disc (14), an inner caliper, interacting with the inner pair (40i, 40e) of friction elements, and an outer caliper, interacting with the outer pair (40'i, 40'e) of friction elements, the two calipers (42, 42') being mounted slidably in the supporting yoke (16). The inner caliper (42) comprises a body (44) in the form of an upturned U, the base (46) of which straddles the inner disc (12) and has an outer wing (48) descending into the gap (D) between the two disc (12, 14) and coming into contact with fraction element (40e) and an inner wing descending on the inner side of the inner disc (12), forming a cylinder (52), receiving a piston (54) in contact with friction element (40i). The outer caliper (42') comprises a body (44') in the form of an upturned U, the base (46') of which straddles the two discs (12, 14) and has an outer wing (48') descending on the outside of the outer disc (14) and comes into contact with friction elements (40'e) and an inner wing (50') descending on the inside of the inner disc (12), forming a cylinder (52') receiving a piston (54'), and the caliper (42') having a spacer (74) in the form of an upturned U, the base (26) of which straddles the inner disc (12) in a radial gap (I) separating the periphery of the inner disc (12) and the base (46') of the caliper and having an inner wing descending on the inner side of the inner disc (12) in order to come into contact with the piston (54'), and a outer wing descending in the gap (D) between the two discs in order to come into contact with friction element (40'i).
