Today's modern brake systems have come a long way in their design, complexity and performance. The cars today are generally lighter and faster, utilize smaller power plants that generate a lot of torque. they run hotter but are quite compared to just a few years ago. The materials used are far more advanced and most are computer controlled.

Needless to say I have seen some vehicles come in that have been improperly repaired by the customer that have led to some very expensive corrective measures. Primarily vehicles equipped with ABS systems (Anti-lock Brakes) CANNOT be serviced using the same methods used on older cars.

There are required accumulator purge procedures that if not performed correctly  have been  known to cause significant damage to ABS components resulting to the brake/anti-lock light coming on after a routine brake job. To repair this type of problem could be a very costly mistake, so to be on the safe side on any vehicle that have an ABS system DO NOT attempt to service but refer to your service professional.

Another problem I have experienced is the installment of sub-standard parts by the customer that results in excessive heat build-up (blue rotors) brake noise and decreased stopping power. Also if the brake rotors are not resurfaced the pads will wear out prematurely, result in a "pulsating brake pedal when stopping and warped rotors

• ABS Systems require special bleeding procedures
• When compressing the brake calipers the bleeder screw should be opened and the fluid recovered in a container rather than allowing the fluid to return through the system to the master cylinder. This is necessary due to the possibility of brake fluid contamination from dirt that may enter the accumulator, ABS pump & valves which may result to damage to the system.
• Rotors should always be re-finished or replaced when servicing brakes to assure the overall integrity of the system is not compromised.
• There IS a difference in the type of pad you install! Cheaper is never better. Cheap pads create high levels of brake dust, causing premature overheating and damage to the rotors. Excessive heat can brake down the fluid and lead to advanced deterioration to the brake systems seals. Use only OE Quality or better pads rated for the type of driving conditions relevant to the application. Don't believe the adds claiming $99.00 brake specials. Remember! You get what you pay for!
