A disc brake for an automotive vehicle which includes: - a brake disc which extends in a plane transverse to a disc rotational axis (A) with an axial orientation; - a fixed support relative to a chassis of the vehicle; - at least one braking pad which includes a vertical transverse lining-holder plate ; -- which holds a friction lining a transverse friction face of which cooperates with an associated braking surface of the disc , the braking pad being axially slidably mounted in the fixed support between a front active position in which said friction face is bearing against the associated braking surface of the disc , and a rear inactive position in which said friction face is axially spaced apart from said associated braking surface of the disc, by a determined running clearance (J1) ; -- which includes, at each of both its opposite transverse ends, a lateral lug with a transverse orientation which is slidably mounted in an associated slide of the fixed support ; -- each lateral lug of which is fitted with a pad spring which is fastened to the associated lateral lug; - and at least one elastic return spring for elastically returning the braking pad to its inactive position including: - a fastening portion for fastening the elastic return spring to the fixed support ; - a connecting branch (B4), with an axial orientation parallel to the sliding direction of the braking pad, which is extended to an active tab which acts on the braking pad , characterised in that said active tab acts on a branch of the associated pad spring . - a brake disc which extends in a plane transverse to a disc rotational axis (A) with an axial orientation; - a fixed support relative to a chassis of the vehicle; - at least one braking pad which includes a vertical transverse lining-holder plate ; -- which holds a friction lining a transverse friction face of which cooperates with an associated braking surface of the disc , the braking pad being axially slidably mounted in the fixed support between a front active position in which said friction face is bearing against the associated braking surface of the disc , and a rear inactive position in which said friction face is axially spaced apart from said associated braking surface of the disc, by a determined running clearance (J1) ; -- which includes, at each of both its opposite transverse ends, a lateral lug with a transverse orientation which is slidably mounted in an associated slide of the fixed support ; -- each lateral lug of which is fitted with a pad spring which is fastened to the associated lateral lug; -- which holds a friction lining a transverse friction face of which cooperates with an associated braking surface of the disc , the braking pad being axially slidably mounted in the fixed support between a front active position in which said friction face is bearing against the associated braking surface of the disc , and a rear inactive position in which said friction face is axially spaced apart from said associated braking surface of the disc, by a determined running clearance (J1) ; -- which includes, at each of both its opposite transverse ends, a lateral lug with a transverse orientation which is slidably mounted in an associated slide of the fixed support ; -- each lateral lug of which is fitted with a pad spring which is fastened to the associated lateral lug; - and at least one elastic return spring for elastically returning the braking pad to its inactive position including: - a fastening portion for fastening the elastic return spring to the fixed support ; - a connecting branch (B4), with an axial orientation parallel to the sliding direction of the braking pad, which is extended to an active tab which acts on the braking pad , <EOS>
