Brakes ne to be maintained forward a regular basis. In an age when many modern vehicle ads create the impression that present cars and trucks need little upkeep if any, this may surprise an consumers.

Though not each automaker lists it in their maintenance manual, flushing and replacing brake fluid is an important preventive maintenance measure Regular inspections and proper lubrication also help obstruct brake system problems.

Q in what way often and why should brake fluid be flushed and replaced?

A Typical manufacturer commended intervals are two to three years regardless of vehicle mileage, as moisture can accumulate in a brake hydraulic theory over time whether the vehicle is parked or driven.

To help obstruct water from accumulating, DOT 3 and DOT 4 brake fluid disperse dampness from head to foot the entire hydraulic system. If brake fluid is flushed and replaced before it has become saturated, or "wet," the moisture does little damage. However, after couple or three years, brake fluid can become saturated. When this happens, the fluid is unable to absorb any additional water, which instead may "precipitate" into droplet This can cause hydraulic order parts to deteriorate from the inside, which is especially precious when ABS components are involved.

An additional, serious effect of wet brake fluid is that it boils at a lower temperature than it does when novel That's bad news for any driver, because the brakes can fail, either partially or completely if the brake fluid boils. Consider the heat generated according to brakes of an SUV towing a trailer by the agency of the mountains in the summer and it is easy to descry the potential, grave consequences of boiling brake fluid--and for what cause brake fluid boiling is not a far-fetched situation.

Q What is the difference between DOT 3 and DOT 4 brake fluid?

The biggest difference between DOT 3 and DOT 4 brake fluid is their boiling point temperatures. DOT 4 has higher wet and craving drink boiling points than DOT 3

However, not all orders designed to use DOT 3 brake fluid will work well with DOT 4 For example, Hyundai prohibits using DOT 4 brake fluid in a certain number of of their DOT 3 supplied classifications Meanwhile, DOT 3 fluid should none be used in a DOT 4 connected view because of its lower boiling point.

Q Is DOT 5 fluid a viable alternative to stock onward my shelves?

A DOT 5 brake fluid does have higher boiling points than DOT 3 or DOT 4 unless it is not desirable for greatest in number automotive braking systems. For single in kind thing, DOT 5 fluid does not absorb and disperse moisture, which may from one side of to the other time lead to the appearance of free water in the plan This is not a desirable condition, considering water's relatively reasonable boiling point and how it can raise rust. In addition, DOT 5 brake fluid aerates more readily than DOT 3 or 4 fluid, making it incompatible for any vehicle with antilock brakes.

Q When should brakes be inspected?

A Anytime a vehicle is upon a lift, technicians should seize the opportunity to at least check the major brake composings Spotting nearly worn pads provides the technician with an opportunity to vend a "hang-and-turn" job before the pads have damaged the rotors--not solitary saving the consumer money, however in some cases, preventing accidents. In addition, finding cracked, weakened trouserss dangerously rusted tubing or an underfilled reservoir provides an opportunity for the technician to correct those unsafe conditions.

More thorough inspections are commended whenever possible. General Motors, for example, calls for periodically checking disc brake pads for freedom of manner of moving to help prevent erratic wear.

Q What lubrication do brakes require?

A Brake pads and shoe influence in relation to the parts that restrain them; lubricating the contact points immediately after installation helps prevent noise, irregular wear and, sometimes, erratic operation. High-temperature lubricants as it is as Bendix[R] Ceramlub, specifically engineered for brake use, are critical in preventing heat from causing the lubricant to post and ultimately damage the brake pads and shoes

Jay Buckley the Bendix[R] Answerman, is a certified Michigan and ASE (Automotive Service Excellence) master mechanic with through 25 years of hands-on automotive repair experience and a rank from Denver Automotive and Diesel guild He fields hundreds of brake repair and maintenance questions each week by brake technicians in the industry.
