A brake arrangement comprising:

• a brake disk means, brake lining means disposed on respective sides of said brake disk means for selective engagement therewith, a substantially planar floating saddle means for selectively moving said brake lining means into and out of engagement with said brake disk means, said floating saddle means being provided with first and second pairs of spaced frame members, said first pair of frame members being disposed on respective sides of said brake disk means and extending in a longitudinal direction parallel to the respective sides of said brake disk means, said second pair of frame members extending traversely of said brake disk means bridging the edge thereof and connecting the respective ends of said first pair of frame members, at least one brake cylinder means operatively engageable with said saddle means for selectively moving said saddle means, abuttment means provided on said saddle means for maintaining at least one of said brake lining means in a predetermined relationship with respect to said brake disk means, a substantially planar brake carrier means for carrying said floating saddle means, said brake carrier means being provided with first and second pairs of spaced frame members, said first pair of frame members of said brake carrier means being disposed on respective sides of said brake disk means and extending in a longitudinal direction parallel to the respective sides of said brake means, said second pair of frame members of said brake carrier means extending transversely of said brake disk means bridging the edge thereof and connecting the respective ends of said first pair of frame members of said brake carrier means, such that said first and second pairs of frame members of said brake carrier means and said floating saddle means defined therebetween a radially extending opening for accommodating an arcuate portion of said brake disk means, said radial opening having a width defined by the spacing between said first frame members of one of said brake carrier means and said floating saddle means and having a length defined by the spacing between said second frame members of one of said brake carrier means and said floating saddle means whereby only said second frame members of said brake carrier means and said floating saddle means extend over the edge of said brake disk means, guide means at each of said second frame members of said floating saddle means for guiding the displacement thereof, guide means at respective side edges of said brake lining means for guiding the displacement thereof, guide groove means provided in each of said second frame members of said brake carrier means for receiving said guide means of both of said floating saddle means and said brake lining means, each of said guide groove means includes a guide groove having an upper and lower surface, each of said guide means of said floating saddle means and said brake lining means includes a projection having an upper and lower surface, each of said upper surfaces of said projection of said floating saddle means engaging only at the upper surface of a respective guide groove, the lower surface of each of said guide grooves is disposed beneath a plane extending through the lowermost portion of said at least one brake cylinder means whereby said brake lining means are exclusively supported beneath the plane by the respective projection means of said brake lining means.
