BRAKE FLUID & a ton of other stuff according to BMW


c.d.iesel

Recommended Posts

for the YOUNG ONES - and a refresher for

old pfharts

Brake fluid, (glycol-based) as used in BMW brake systems, must conform with the following requirements:

— High boiling point

— Good low temperature resistance

— Low compressibility

— Corrosion inhibition for all metal parts inside of brake system

— Compatibility with all rubber parts used in brake system

These requirements are fulfilled by reputable brand name DOT 4 brake fluids.

Silicone-based brake fluid has better compressibility, but because

it cannot absorb moisture, is subject to vapor lock

attemperatures above 212°F/ 100°C. At lower temperatures, it

may even ice-up. Silicone-based brake fluid is not approved by BMW.

Glycol-based brake fluid absorbs moisture from the atmosphere (hygroscopicity) through the brake fluid reservoir, brake

hoses, etc. This absorption of water lowers the original boiling

point of brake fluid and active safety of the entire system.

If there is extended use of the brakes while driving downhill at high speeds, the thermal loads could cause vapor bubbles

in the brake fluid. This situation could lead to reduced braking effectiveness.

The original boiling point of factory-approved brake fluids is

approximately 500°F/260°C. Due to the hygroscopic behavior

of brake fluid, 2% of water within one year is permissible. The

boiling point of brake fluid will drop by 100°C with 3% water

absorption. It is essential to conform with brake fluid changing

intervals in order to guarantee the safety and maximum

effectiveness of a brake system.

It would not be sufficient simply to replace the brake fluid in the

reservoir. Experience has shown that vapor bubbles will

occur first on areas of the brake caliper. This area is subjected to

high thermal loads and also exposed to heat transmission.

When replacing the brake fluid, the brake fluid used as the working

fluid in the hydraulic clutch should also be replaced.

This is done by draining the clutch operation system or bleeding

with the help of the clutch slave cylinder.

The brake fluid should be replaced by filling the brake fluid reservoir. Make sure that each bleeder valve of all wheel

cylinders or brake calipers is kept open until the escaping

brake fluid is clear and without air bubbles. Never use brake

fluid that has been drained from the system.

Storage of brake fluids also deserves your special attention.

The aging process begins with the initial contact between the

brake fluid and the atmosphere. This means immediately after

a new container is opened.

To keep the boiling point of stored brake fluids as high as possible,

we recommend conforming with the following points:

— Close all containers tightly.

— Select small size containers, which can be used up quickly.

— Avoid pouring contents of one container into a different container.

2.0 Handling Brake Fluids

Brake fluids could be mixed up accidentally with mineral oil

products so it is important to leave them in their original

containers and not pour them into a different container.

Caution

If brake fluid accidentally comes into contact with your skin,

wash it off with soap and water immediately. Eyes should be

thoroughly flushed with cold water if contacted by brake fluid.

Vomiting should be induced if brake fluid is internally

consumed and a physician should be consulted.

If brake fluid is spilled or drips on a painted surface, wash it

off with water immediately to prevent damage to the paint

finish. Never rub it off. Brake fluids should not have contact

with grease or oil. Wash hands to remove grease and oil before

working with brake fluids. Also make sure that grease cannot

enter the brake system.

Drained brake fluid must never be discarded in the garbage,

oil disposal tanks or water drains.

Read instructions on container label prior to use.

1.0 Introduction

These operating fluids specifications describe the standards

which are necessary for approval and application for

BMW automobiles. Operating fluids are arranged in vehicle

group category and are approved for all assemblies. Any

reference to a particular fluid contained in an active Service

Information Bulletin since January 1987 will be listed next to

the fluid’s part number. Before applying operating fluids, it is

important to make sure that the specifications and

manufacturing codes on the container conform with those

on the enclosed specification list.

Prior to their approval, all operating fluids are tested in detail on test stands, in laboratories, and in cars during field tests.

As new information is received, the Operating Fluids Manual will be updated. Some lubricants or fluids may be listed in

more than one specific group.

For example, Part No. 81 22 1 468 879 (Pentosin CHF7.1 Fluid) is listed under Group 32

(Steering) as well as in Group 37 (Integrated Suspension Systems).

BMW Car Care products are listed in Group 99.

BMW of North America has also approved various fluids for use which are not available through the Parts Department, but

may be obtained locally. A list of these approved fluids is found on sections 4.0 and 5.0.

Some fluids have been phased out of PDC inventory. Such fluids will be marked by an asterisk (*) after the part number

along with the name(s) of alternate supplier(s) and the product

name/part number.

A binder containing the Material Safety Data Sheets (MSDS) for

BMW NA distributed Chemical Products was sent out

with Parts Bulletin 99 05 97. Questions on the use of this

information may be directed to the Safety and Health

Officer (201-307-3623) or to the Parts Consultant Group (800-272-0202).

2.0 Corrosion Protection For Vehicle In Long-term Storage

Location - inside of a building whenever possible or covered

parking lot (especially convertibles).

Replace engine oil and filter after engine reaches operating

temperature. Run engine several minutes after replacing oil.

Engine oil must be replaced every 12 months. Factory engine

oil (in new cars) can remain in the engine up to 12 months.

Check/correct electrolyte level in battery cells.

Disconnect battery ground lead to avoid discharging battery

through current draw of electrical equipment. Or, switch off

battery main disconnect switch (if equipped).

Recharge battery according to S.I. Bulletin B 61 07 88.

Inspect undercoating for damage and repair as necessary.

Inspect wax coating in engine compartment, on engine,

underbody and axles. Repair as necessary.

Operate air conditioner monthly for 10 minutes in order to

lubricate the seals and the expansion valve. Note: The air

conditioner will only work at temperatures above 37°F/3°C.

Pre-Delivery Cars

Replace brake fluid if car has been parked outdoors longer

than six (6) months.

Fill the vehicle fuel tank with fresh fuel in order to prevent

condensation inside the tank (applies only to metal fuel tanks).

Check, and if needed, correct the coolant level and

concentration of long-term antifreeze and corrosion inhibitor.

Apply brakes to dry the brake discs of any moisture and spray

them with a corrosion inhibitor. Spray the complete brake

assemblies after parking the car at its final storage location.

Do not apply the parking brake. Brake linings could seize

when the parking brake is applied for an extended period of

time. Rather, engage first gear (manual transmissions) or

“park” position (automatic transmissions) to hold vehicle

stationary.

Increase inflation pressure on all road tires to 50 psi.

Thoroughly clean the entire car, including underside, engine

and engine compartment.

Exterior Finish

Repair any damage to the paint finish. Wash entire vehicle

exterior with BMW Car Wash Shampoo (Part No. 82 14 9 400

129) or equivalent. Polish painted and chrome finishes with

Car Polish Cream - 3M Part No. 6055 (former BMW Part No.

82 14 9 400 131) or equivalent.

Polishing the vehicle with abrasive cleaners and/or cleaner

waxes may have a detrimental effect on the appearance of

the paint. Waxing of Paint Sealer treated vehicles may still

be done, but only if non-abrasive cleaners or non-abrasive

cleaner-waxes are used.

Wax painted and chrome finishes with BMW Car Wax

(Part No. 83 12 9 408 527) or equivalent.

Wax painted and chrome plated parts if storage period

is 12 months or longer. Dewax and rewax cars every six (6)

months if stored outside.

Check convertible top for damage.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,
