Q: I have an anti-Lincoln Mark VII.
Lock brake system.
These types of brakes are new to me.
When I try to park, the brakes create a feeling of instability.
I complained to the dealer but was told it was the normal function of the brake system.
After 18,000 miles, I had to replace the rotor because the pad was not fully recovered.
After the repair, I never experienced the raw feeling of braking.
These new reactions
The lock brake system feels different from the old brake system, is the updated brake pads worn faster? --K. D. W. Answer:
There are sensors on the wheel of the locking brake system, and when a specific brake device locks or starts to slip on the road surface, the sensor reports to the computer.
In the event of a lock, the computer takes over and commands the system to start the pulse brake in a somewhat similar manner to the manual pump delivery brake to prevent loss of control. But in an anti-
Lock system, very fast pulse--
About 12 times per second.
The way each system works is different, but usually the pulse happens so fast that you can\'t really detect it from the feel of the brake pedal.
If you experience a pulse or beat of the brake, it is more likely to be caused by a defect in the brake rotor or drum than by a counterlock system.
Twisted rotor or out-of-
The drum will cause obvious fluctuations on the brake pedal.
The failure of the pad retraction is not uncommon.
In the old drum system, the brake shoe is pulled back from the drum through a solid spring.
But in the disc brake system, the brake pads are pulled back from the rotor (or disk)
Elasticity of rubber seals.
Due to the aging of these seals or the damage of contaminated brake fluid, they may not be able to complete the work.
As a result, the pads will be too early on the rotor and wear.
If your rotor is twisted, it can cause pad wear even if there is no failure of the rubber seal.
The twisted rotor swings during rotation, thus scraping the liner during rotation.
In the end, the pads wear and the metal back plate will damage the metal rotor.
The pads no longer contain asbestos, but that doesn\'t mean they wear out faster. The new semi-
The metal pads are fairly hard and actually durable than the old ones.
Besides, they do not cause lung cancer.
Q: New EC of Arco-
1 gasoline is sold as a substitute for lead gasoline but not lead.
Since it\'s cheaper than unleaded gasoline and has a higher Cetane value, why can\'t I use it on a new car that uses unleaded fuel? --L. L. K.
You can use it except for a question.
Nozzle on EC-
1 The pump is designed to fit the neck of the tank with lead gasoline.
The nozzle is too large to fit the neck of lead-free fuel.
As a marketing decision, Arco wants to limit fuel as a lead fuel alternative.
Ironically, this fuel is not a lead-free alternative.
In contrast, Arco believes that lead-free fuel has little damage to the old engine designed for lead fuel.
The reason is that unless the engine is subjected to high load at high rpm, there is little chance of damage to the engine valve.
Many owners of classic cars disagree, but Arco and other refiners insist that they have test and technical data to support their claims.

Anyone riding a bicycle with a spring coil shock absorber on a hard and undulating surface will know how different and efficient the damping of pneumatic and hydraulic shock absorbers is.Today\'s impact is a very advanced shock and damping vibration device that can work on compressed air power or liquid to dissipate the energy and vibration generated by the tire\'s contact with the road surface.The impact pulse dissipated through the pneumatic and hydraulic cylinders with a sliding piston device inside.
The cylinder is filled with fluid or air as required.Shock absorbers are used not only for engines and car suspension, but also for aircraft landing gear, drilling equipment, earth-moving equipment, oil rigs and many other large industrial machinery.In rail transport, the principle behind the shock absorber is the same, which limits the steering of Bogota from one side to the other in fast-moving trains.
Pneumatic and hydraulic damping systems contain pneumatic cylinders or hydraulic cylinders that use steel pistons, piston rods, cylinder cylinders to help achieve damping effects.When compressed air or fluid enters a pneumatic or hydraulic cylinder, it pushes the piston up or down through the length of the cylinder.The reflective action of the piston is either activated by compressed air or by the spring mechanism, and the spring returns to its original position.
These are also called single action cylinders.There are many types of cylinders, which can be cylinders, electric cylinders, hydraulic cylinders or electric hydraulic cylinders.The dual-acting cylinder (DAC) uses the power of the air to move in two ways, one is to extend the stroke and the other is to retract the stroke.
The dual action cylinder has two ports, one for the outer stroke and one for the inner strokestroke.As industry requirements may vary, there are a wide variety of holes and stroke configurations for pneumatic and hydraulic cylinders.These may vary between less than inches until a few feet.
The power of compressed air or air may range from a few pounds per square inch to a few hundred pounds, generating enough power and a few thousand pounds of force.The piston rod is usually made of tempered alloy.The cylinder tube is seamlessly stretched, with precise sanding to achieve the smoothest finish to prevent corrosion and provide long life for the pistonseals.
The valves inside the pneumatic and hydraulic cylinder help to adjust the flow of compressed air or fluid and maintain the pressure of the internal pressure of the pneumatic or hydraulic cylinder.Some pneumatic cylinders have a diameter of 1000mm and are used instead of hydraulic cylinders in special cases where leakage of hydraulic oil can cause extreme danger.Pneumatic and hydraulic cylinders are also suitable for automatic blinds of trains and electric doors, as well as automatic exits monitored and activated by sensors.
Low friction properties arranged in pneumatic and hydraulic cylinders enable it to be smooth and slowFast operation under low pressure, which is a safety consideration in the field of human transportation
