Abstract
The invention provides a method of apparatus for refinishing a vehicle brake disc. The brake disc is rotated while in place on the vehicle and is brought into contact with one or more abrading discs, which are rotated as well, thereby grinding the brake disc. The abrading discs are maintained in contact with the brake disc by being mounted on a holder which is secured into a portion of the vehicle which is fixed with respect to the brake disc. The preferred arrangement is to attach the holder to the brake caliper mounting associated with the brake disc to be ground. In a preferred embodiment two abrading discs are used, and they can be adjusted to be slightly out of parallel with one another, so as to grind the brake disc with more pressure in a desired region than in another region.

Apparatus for regrinding a vehicle brake disc mounted on a vehicle which apparatus comprises:
- a rotatably abrading disc having an abrading face and being fixedly mounted for rotation about an axis at right angles to said face;
- means for mounting such abrading disc from a portion of a vehicle which is fixed relative to the axis of the brake disc, such that said abrading face is positioned for rotation on a side of such brake disc in face-to-face frictional contact with such brake disc.
Apparatus for regrinding a vehicle brake disc which apparatus comprises:
- a rotable abrading disc having an abrading face and being fixedly mounted for rotation at right angles to said face;
- means for mounting such abrading disc from the caliper mounting of a vehicle such that said abrading face is positioned for rotation on a side of a brake disc mounted on such vehicle in face-to-face frictional contact with such brake disc.
Apparatus for regrinding a vehicle brake disc which apparatus comprises:
- two rotatable discs each having an abrading face and each being fixedly mounted for rotation about an axis at right angles to its said face;
- means for mounting said abrading discs from a portion of a vehicle which is fixed relative to the axis of rotation of the brake disc such that said abrading faces are positioned for rotation one on each side of the brake disc mounted on such vehicle and in face-to-face frictional contact with such brake disc.
Apparatus for regrinding vehicle brake discs which apparatus comprises:
- two rotatable abrading discs each having an abrading face and each being fixedly mounted for rotation about an axis at right angles to its said face;
- means for mounting such abrading discs on the caliper mounting of a vehicle such that said abrading faces are positioned for rotation one on each side of a brake disc mounted on such vehicle and in face-to-face frictional contact with such brake disc.
Apparatus for regrinding a brake disc in situ on a vehicle axle, which apparatus comprises:
- a base member;
- two relatively movable supporting members upstanding from the base member;
- grinder support means supported by each of said supporting members;
- axle means journalled in said grinder support means;
- an abrading disc fixedly mounted on each axle means for rotation therewith, each abrading disc having a face perpendicular to its axle means, the face being provided with abrasive means;
- said two abrading discs being orientable with their respective abrasive faces in face-to-face relationship to one another;
- means for urging said abrading discs towards one another, and;
- means for removable and adjustably attaching said base member to a portion of a motor vehicle which is fixed with respect to the axis of rotation of a brake disc on that motor vehicle, which brake disc is to be reground with the said abrasive faces on opposite sides of a vehicle brake disc and in contact with said vehicle brake disc.
Apparatus for regrinding a brake disc in situ on a vehicle axle, which apparatus comprises:
- a base member;
- two relatively movable supporting members upstanding from said base member;
- a grinder support means mounted on each of said supporting members;
- axle means journalled in each of said grinder support means;
- an abrading disc fixedly mounted at the end of each axle means for rotation therewith, each abrading disc having a non-abrasive face, in which its axle means terminate perpendicular to said non-abrasive face, and an abrasive face on the other side of said disc;
- the face being coated with abrasive material;
- said two abrading discs being orientable with their respective abrasive faces in face-to-face relationship to one another;
- means for urging said discs towards one another;
- and,
- means for removably and adjustably attaching said base member to the caliper mounting of a vehicle brake disc unit with said abrasive faces on opposite sides of a vehicle brake disc and in contact with said vehicle brake disc.
A method for regrinding a brake disc in situ on a vehicle, said brake disc being rotatable about an axle of said vehicle, which method comprises:
- providing at least one abrading disc having an abrading face and rotatable about an axis of rotation perpendicular to its abrading face;
- mounting said abrading disc from a portion of the vehicle which remains fixed with respect to the axis of rotation of the brake disc, with said abrading face of said abrading disc in face-to-face frictional contact with a face of the brake disc to be reground;
- and,
- rotating the brake disc while maintaining such frictional contact and such perpendicular relationship of such abrading disc to its axis of rotation.
A method for regrinding a brake disc in situ on a vehicle, said brake disc being rotatable about an axle of said vehicle, said vehicle also being provided with a brake caliper mounting bracket to mount brake calipers associated with said brake disc, which method comprises:
- providing at least one abrading disc having an abrading face and rotatable about an axis of rotation perpendicular to its abrading face;
- mounting said disc on said caliper mounting bracket such that the abrading face of such disc is in face-to-face frictional contact with the brake disc to be reground;
- and,
- rotating the brake disc while maintaining said frictional contact and such perpendicular relationship of such abrading disc to its axis of rotation.
A method for regrinding a brake disc in situ on a vehicle, said brake disc being rotatable about an axle of the vehicle, which method comprises:
- providing two abrading discs each having an abrading face and each rotatable about an axis of rotation perpendicular to said abrading face;
- mounting said discs from a portion of the vehicle which is fixed with respect to the axis of rotation of said brake disc, such that the abrading face of each disc is in face-to-face frictional contact with a face of the brake disc to be reground;
- and,
- rotating the brake disc while maintaining such frictional contact and such perpendicular relationship of such abrading discs to their axis rotation.
