The Importance of Brake Service

Importance Of Brake Service

I think you’ll agree that your brake system is the most important safety system on your car. At Anoka Auto Care, we take your car’s brake system very seriously. Because of this, we have invested heavily in equipment, tools and personnel to make sure that any brake system we service will be brought back to factory performance standards or better.

Personnel:

Every brake job at Anoka Auto Care is performed by an ASE Certified Master Technician. Certified in every area of your car, not just the brake system. Because so many of your car’s systems are integrated with each other, we believe that in order to do a good job on any part of your car, the technician needs to fully understand the entire car. To see if your Technician is Master Certified, look for a gold bar on his certification patch that reads “Master Auto Technician” or ask to see their ASE Certification credentials.

Equipment:

Anoka Auto Care has the finest brake equipment money can buy. Of course we have the normal brake fluid flushing, rotor and drum resurfacing equipment but it doesn’t stop there.

For bleeding and flushing brake fluid we have the Ammco pressure bleeder and the Phoenix Injector:

When we realized that disc brake pulsations were the number one brake complaint of drivers nation wide, we invested in the most sophisticated disc brake rotor refinishing system available; The Pro-Cut PFM 900. This is not only the most accurate refinishing system on the market but it is also the fastest one we tested. This is an “on the car” refinishing system that compensates for run out caused by corrosion and stacking. Corrosion is unavoidable in this part of the country so there are only 2 ways to prevent it from becoming an issue in a brake service operation; either replace the rotors and the hub and wheel bearing assembly with every brake job at outrageous expense, or use the Pro-Cut refinishing system to restore the system run out to factory specs. Stacking is another big concern on modern disc brake systems. This is unavoidable. Small inconsistencies in the disc brake rotor and wheel bearing hub that are acceptable for the individual components will usually grow to become unacceptable when the components are bolted together. There is only one cure for this; bolt the components together and finish the rotor on the car with the Pro-Cut system. This is also the only brake lathe recommended for use by GM, Ford and Chrysler. The expense of this type of equipment has prevented most auto repair shops from purchasing it but we think that you are worth it.

The above pictures show a brand new premium rotor installed on a 1995 Ford Explorer rear hub. After a thorough cleaning and careful torque procedure there is still over seven thousandths (.007) run out. The maximum run out for a newly reconditioned brake rotor on this vehicle is three thousandths (.003). Without the Pro-Cut system this rotor would leave the shop with more than twice the maximum run out recommended by the manufacturer. By using the Pro-Cut system we can get the run out under one thousandth (.001) every time.

We also have the standard industry “work horse” brake lathe for refinishing brake drums and rotors when “off the car” refinishing is desired:

Brake parts:

We use the best brake parts money can buy. Raybestos, the official brake pads of NASCAR.

Proper lug nut torque can improve safety and smooth stops.

On every wheel all lug nuts should be snugged up in the proper sequence first, then final torqued with a torque wrench using the proper torque specs and the proper torque patterns for that particular application. This will prevent cantilevering of the wheel to the mating surface which has been proven to cause wheels to loosen up. It can also prevent warping of rotors, wheels and hubs. Never snug or torque lug nuts using a circular torque pattern, even if the car has drum brakes, as it will put extreme stress on the wheel, huband rotor in the area between the first and last lug nut that were tightened. This willcause warping and in some cases irreparable damage to the hub. Warped rotors and hubs are what cause annoying brake pulsations.

All aluminum wheels should be retorqued within 50-100 miles of installation. Aluminum wheels expand with heat generated by the brakes and contract after cooling down at a much greater rate than traditional steel wheels. This expansion and contraction can loosen the lug nuts and usually happens shortly after wheel installation. Once retorqued the chances are slim that the wheels could loosen but they still should be checked periodically. Some aftermarket aluminum wheels may require many retorque procedures.

This inexpensive service can make your car safer an save you money at the same time!

Changing your brake fluid regularly is probably the most important thing you can do for your brake system. In the long run it will save you money by keeping expensive brake system components like calipers, wheel cylinders and anti-lock brake valves from corroding and sticking. Nearly all brake system manufacturers recommend flushing your brake systemat least every other year to keep moisture from corroding the system and to keep debris from accumulating in cylinder bores. We have a short movie clip of what 5 year old brake fluid looks like being pumped out of a caliper bleed screw. When you view this movie, notice that the fluid is coffee colored instead of clear like it should be. Also notice that just before the end of the piston travel it turns into mud. This muddy looking sludge is debris that has accumulated in the bottom of the caliper bore. Caliper pistons need to be compressed in order to accommodate new disc pads which are always thicker than the worn out pads that are being replaced. Had the bleeder not been open during piston compression this sludge would have been forced into the master cylinder and anti-lock brake components. This could have caused thousands of dollars worth of damage to the brake system. Also this caliper is in danger of sticking because the sludge has been compacted around the piston as it was pushed back. This caliper should be overhauled or replaced. Of course this could have been prevented had the brake fluid been flushed as recommended by the manufacturer. This is why at Anoka Auto Care we clamp the hoses and open the bleeders when compressing caliper pistons on every brake job. We also open all bleeder screws and completely flush the brake fluid on every brake job. We feel that this inexpensive service is the most important yet overlooked service in the automotive industry today.
