What is Brake Fluid?

PEG Products +

• Laxatives• Eye Drops• Skin Creams• Tooth Paste• Printer Ink Solvent• Spandex• Foam Cushions• Paintball Fill

The Base of brake fluid is made up of polyethylene Glycol or PEG for short, Which is also known as Anti-Freeze. (Not Oil Based) PEG is used to make products like eye drops and spandex.

Motorist Assurance Program (MAP)was created to

protect the interest of:

• Auto Repair Industry

• Vehicle Owners

MAP Missions

MAP’s mission is to insure consistency in inspections of vehicles and communication of that inspection to the customer.

Who is MAP?

Uniform Inspection and Communication Standards

Shops needed uniformity in repair recommendations

Customers needed more information to make an educated decision

(Company) has printed hand out that say manufacturers recommend replacing brake fluid once a year or each 12,000 miles. I've researched for hours on the net and calling all kinds on dealer service departments, I haven't found any recommends for brake fluid replacement under 50,000 mile unless the fluid becomes contaminated. BS statements to make more profit. From what I've witnessed most of the techs don't even do a proper bleed and flush. Some agency should conduct and investigation and interview current and past employee's. (Company) would be in poor shape if they were checked out by the attorney general and or TV-radio stations.

COMPLAINTS

WHEN SHOULD YOU CHANGE BRAKE FLUID?

Every 24,000 miles?Every 36 months?It’s Hygroscopic and absorbs moisture?Replace if color is dark?Its just a good thing to do?

WHAT’S RIGHT???

Do NOT have SERVICE INTERVALS

Most Imports service interval is 24 to 36 months or 24-36,000 miles

HygroscopicMoisture lowers the

boiling point

Moisture Testing

Absorbs moisture

Wet & Dry Boiling Point STANDARD 116

DRY BOIL WET BOIL

IS MOISTURE A PROBLEM?

• Very rare today• OE Fluids have higher boiling points• System design changes• Studies by Ford showed less than 6% of cars tested failed a moisture test.

SAE 2001-01-0947

Hoses with rubber inner layers did not resist moisture as well as today’s hoses with EPDM inner layers.

MAP moisture guidelines as of 11/01/2003

• While moisture is an issue with brake fluids The measurement of moisture that is detrimental to brake fluid performance has not been found.

• In additionNo specification exists for an in-use brake fluid boiling point.

Therefore no recommendation for replacement based on moisture content can be made with confidence.

COLORIs it Good or Bad?

• New fluid specification is colorless to amber.

• Dye from seals and hoses may cause the brake fluid to turn a darker color.

• New vehicles have been found to have dark fluid even before being driven.

2 Functions of Brake Fluid

1. Apply hydraulic pressure to brake components to slow the vehicle

2. Protect the Brake System from CORROSION

COPPER

Direct relationship to depleted corrosion inhibitors

1 Copper Where does it come from?

It comes from the steel brake lines

Copper bracing is used to fill in the spaces in-between the spiral steel lines

Copper Is … +

• Early Warning for iron corrosion

• Indicator of lost buffering capability

• A cholesterol test for your car.

SAE, Jackson, “After 30 months of service copper reached 200ppm”.

NIST, Ricker, “The hypothesis that the large surface area of copper in the brake lines corrodes slowly during normal service resulting in the accumulation of copper ions in the brake fluid that can be transported to other parts of the braking system and cause corrosion of ferrous alloys, once the corrosion inhibitors become depleted”.

NIST STUDY

ABS systems have increased brake fluid mixing results in the corrosion inhibitor concentration decreasing faster.

ABS systems use close tolerance valves that must operate quickly and more concisely than conventional braking systems.

ABS systems are more susceptible to degradation in performance due to corrosion or deposits.

NHTSA investigated sudden increased pedal travel due to a leak in the modulator dump valve. Their findings of the cause of valve leakage was “very small particles of pure copper present in the area of the valve's dump seat and sealing surfaces.

Here is a chart that shows a relationship to copper versus iron. On the left-hand side here, you can see we have parts per million and across the bottom are months. You can see the pink is the iron which goes up the scale in relationship to the copper. As the copper increases so does the iron.

MAP Uniform Inspection &Communication Standards for Brake fluid

Component : Brake Fluid

• At or beyond OEM service interval Suggest service

• Brake fluid type incorrect Require flushing • Contaminated Require flushing

• Corrosion inhibitors depleted Require flushing

A copper content of 200 ppm or greater indicates a depletion of corrosion inhibitors in the brake fluid

• Hydraulic component overhaul or replacement Recommend fluid exchange

Customer’s Brake Fluid Corrosion Test Results

Brake Fluid FlushingPRESSURE IS THE BEST METHOD

1. Apply brakes a few times to suspend contaminants in brake fluid.2. Remove old brake fluid and contaminants from reservoir. 3. Add new brake fluid to reservoir.4. Hold down brake pedal 1 inch to allow fluid to escape from master

cylinder chamber.5. Perform OE bleeding instruction including correct sequence.6. Use at least 1 quart to ½ gallon of new brake fluid to pass through

system. (1 minute flow at each bleeder).

“The test strips are great and most of our brake flushes come from the test strips. The guys love to use them and it makes them extra money.”

“The brake flush strips have increased flush system sales 70% at our location over the previous year.”

“Test strips work great and increase the trust factor in the relationships with my customers.”
