  Servicing Disc Brake    
  This is a general overview of common brake problems and errors made during "on the car" brake disc service.  
  Modern Disc Brake Design    
Today's automobile manufacturers are equipping new cars and light trucks with either two-wheel or four-wheel disc brakes. These systems provide improved vehicle deceleration, weight reduction, simpler inspection and maintenance. All car manufacturers are also paying ever-increasing attention to safety, cost of maintenance and comfort, which dictates that correct service of the brake system is essential.
  Brake Maintenance    
Friction between the disc pad and disc generates heat and wear. Optimum brake deceleration can only be achieved if both components are flat and parallel. If one of the components is replaced , the other must be corrected in order to provide correct brake performance. Braking efficiency can be reduced by as much as 20%, when only pads are serviced leaving the disc glazed and not flat or parallel.

  Brake Problems      
Because of constant refinements in manufacturing tolerances, quality awareness, as well as advances in steering and suspension technology, the driver notices even minor defects in the disc brake system. Vibrations in the steering wheel or brake pedal are felt immediately and brake noise is also audible. There are three directly attributable causes:

Run-out is the oscillation of the brake disc . This may be caused by tolerance in the brake disc or hub or by the distortion of these parts by shock loads. The oscillation of the brake disc can be felt in the steering wheel. The brake disc and pads are not in line. (Parallel)
Disc Thickness Variation (DTV) is the difference in the thickness of the rotor, measured at various points around its circumference. This is caused by differences in material structure, run-out and changes in brake conditions, such as ambient temperature and load rates. DTV can clearly be felt in the brake pedal in the manner of a pulse. Roughness of the disc surface leads to high or low frequency vibration of the brake components. The differences in surface structure do not not conform to the manufacturer's specifications and will result in excessive brake noise.
  Possible Solution    
  Mad Aligner There are possible solutions for eliminating the problems of disc run-out; OTV and roughness. However, these are not necessarily cost effective or permanent. 1) Replacement of the brake disc is expensive and usually results in a recurrence of the problem . Also, if there is a slight oscillate ion of the hub, it will continue to cause a vibration.
2) Use of a bench brake lathe to resurface the disc , adds to the expense of disassembly and requires precise adjustment upon reassembly. Again, if there is any hub oscillation present, the vibration will continue .
3) New discs and pads are the only way to assure flat surfaces but is far more expensive and also does not eliminate the possibility of hub oscillation. Many OEMs require new rotors to be lightly surfaced once installed, so as to insure that it matches the hub for proper brake operation.
  The Proper Solution: MAD DA 2002 Disc Aligner  
Most car manufacturers agree, that the only correct method to eliminate brake problems is to realign the brake disc on the car. They also agree that it is vital to use the caliper mounting point as the alignment reference. This assures that only now you achieve parallel surfaces once again.
The Results
Correct alignment achieved, all of the brake problems are solved in one step, requiring an average of only 20 minutes for each rotor, which includes the removal and reinstallation of the tire and wheel assembly. Once again the original brake performance is restored .
