Here are some more information for Rear Emergency:

Large SUV's built on truck chassis present a serious danger to others (DTO) on the road. A truck-based SUV provides about 5% greater safety for its occupants than a car does in a front, rear, or side crash, and deals about a 300% greater risk of death to the people in any vehicle it hits. The Insurance Institute for Highway Safety looked at deaths per million miles driven and found that large SUV's involved in two-vehicle accidents inflict far more damage on other vehicles and their occupants. The reason is simple physics.

Full size SUV's and pickups weigh about 1000 pounds more than the average car. A vehicle that weighs a half ton more delivers a far greater destructive force on impact. Add to that a significant difference in the vehicles' construction. SUV's and pickups are built with stiff frame rails. When an SUV or truck rams another vehicle, it doesn't give. It transfers the force of impact to the other vehicle. Cars, minivans, and small SUV's built on car frames are designed with energy-absorbing structures. They're built to absorb and the force of impact, and because the SUV isn't, the smaller, more flexible vehicle absorbs more force.

SUV's are taller than cars, with higher road clearance, and their height makes them more dangerous to other cars. The modern car bumper is a superbly designed energy absorption system. But in front and rear end collisions, the tall SUV is likely to ride up over the other vehicle's bumper. When the SUV rides over the bumper and pushes its way into the engine compartment or the trunk, the bumper's energy absorbing value is lost. In side crashes, the SUV's height means it can ride over the car's door-frame and T-bone directly into the passenger compartment.

In rollovers, SUV's are also DTS, danger to self. Large SUV's are at much higher risk of rollovers than other vehicles. Again, it's simple physics. Its height and resulting high center of gravity make it much more likely for the vehicle's rear end to fishtail, or slide sideways in a tight turn or an emergency braking maneuver. The SUV's height and high weight distribution mean that once the vehicle is moving sideways, it's much easier for it to flip and roll over once or multiple times.

When a pickup or SUV rolls, it exposes its occupants to much more danger of roof crush, the collapsing of a roof under the weight of the vehicle. Physics again: The vehicle's weight, including that extra thousand pounds, is now on top, crushing down on a roof that too often is simply not designed to support it. Most pickup and SUV roofs are not unibody construction. The incremental cost of a unibody roof and sturdier metals would run about $50 per vehicle, but manufacturers have chosen not to make this simple improvement.

If you or a loved one has been seriously injured, or your loved one has been killed in a crash involving an SUV, you will want to consult with an experienced SUV crash attorney to determine whether you may have a case against the manufacturer. It is important to do this as soon after the crash, to assure that the SUV involved is not destroyed, as it will be vital evidence in your case.

Your SUV attorney will want to have an automotive design safety expert examine the vehicle. In rollover cases, particularly consultants and experts help your attorney put together the most accurate and case for presentation to an arbitrator or a jury.

Auxiliary emergency vehicle lights are a welcome sight in emergencies

Besides these main emergency vehicle lights, there are smaller lights on most emergency vehicles known as auxiliary lights. These help the vehicle users in their jobs in various ways. More common auxiliary lights are spotlights, floodlights, load lights, alley lights, and take down lights. The most common face of emergency lights is the LED light bar with its blue, red, and white lights. It is a frequent sight on most streets as the police have these lights on their routine patrol cars, as well as on their vehicles engaged in emergency services. Emergency vehicles lights are the insignia that demarcate emergency vehicles from the rest and give them the right to cross speed limits and ignore other traffic rules.

Emergency vehicle lights, sirens, communication devices, medical equipments, and other duty aid devices carried by emergency vehicles are collectively known as emergency vehicle equipment. Different types of emergency vehicles will have different devices that form part of this larger equipment pool, but a common item in many of them, besides emergency vehicle lights, are what are known as auxiliary lights.

The more conspicuous emergency vehicle lights are larger light bars, strobe lights, rotating beacons, smaller deck lights, dash lights etc. Auxiliary lights are necessary to aid in the work that the vehicle is involved in, or to supplement the light provided by the more prominent emergency vehicle lights. Small spot lights mounted on the top, sides, or back of smaller emergency vehicles, and larger flood lights that can be fixed the same way in larger vehicles, to provide extra illumination are called auxiliary lights.

Ambulances, which generally use rotating beacons or light bars as its main emergency vehicle lights, may have auxiliary lights known as load lights near its rear doors through which the injured individuals and attendants get in. Towing trucks or other emergency vehicles, which have cargo doors, for extra light in the area surrounding the cargo door, may also use such load lights.

Police vehicles, which use LED light bars as emergency vehicle lights for warning as well as traffic direction, use additional lights known as alley lights. These may be mounted on the sides of the police vehicle, or on the sides of the light bars itself. Alley lights are necessary to light up alleys, that is, both the sides of the road through which the vehicle is passing, as the main light will be designed to focus forward.

Take down lights are lights added to emergency vehicle lights to light up the interior of the car in front, which the police vehicle might be searching or chasing. These lights help the police in spotting contraband items in the car, or people who are trying to hide or escape. The high intensity take down lights are also useful in temporarily disorienting suspects with its brightness.

Even where the police are not chasing another vehicle, takedown lights help the main emergency vehicle lights in illuminating a crime scene or an accident scene in front. The quality of take down lights also help in improving the quality of the photographs and videos done of the vehicle in front, or of the crime scene or accident scene ahead. Though they are small, auxiliary lights aid emergency vehicle lights, in their job in a big way.

Replacing the Emergency Brake Shoes inside the rear disc on a O3 Town & Country?

Do I have to remove the Hub to get at all of the springs??? Where could I find some pictures

I can't say I have experience with that particular model but of the dozens I have seen they are not that complicated; if it is not AWD then the hub is easily removed making the parking brake assembly easily accessible. The hardest part of this type of job is removing the rotor due to the buildup of rust on the inner drum so I would suggest buying the hardware kit as well as the shoes.

There are fewer parts than conventional drum brake assemblies because it is only mechanically actuated so it's pretty easy to tell which spring goes on the top and which one goes on the bottom. The fact that you are considering doing this yourself is indication enough that you should have no trouble figuring it out.
