A few sprays of brake cleaner onto your pads and rotors will break up and dissolve caked-on grunge. Rinse will clean cool water and immediately dry to prevent rust formation onto the rotor face drum brakes will require physical disassembly. Brake friction material is available in a wide array of compounds, but these compounds fall into three basic categories:. Some compounds are engineered for general use while others can be delegated to perform in a specific environment such as heavy towing or race applications.
Most modern ATVs use hydraulic disc brakes on all four corners. The advantages of disc brakes are the same as they are in cars and trucks; disc brakes stop quicker and more effectively. Both discs and drums rely on heat and friction in order to work but disc brakes can better manage the heat since they are exposed to open air and not enclosed like drum brakes.
Drum brakes trace their lineage back to the earliest automotive braking systems, just slightly more refined than the old-fashioned handbrake. Drum brakes are perfectly acceptable under most normal riding conditions but their major drawback is their tendency to overheat. Drum brakes operate at a reduced capacity over discs and are not recommended for any type of sport riding or competition.
They are, on the other hand, cheaper to manufacture and cheaper to replace albeit, more difficult to service. Disc brakes are the preferred option for high-performance riding and motorsport as they allow for enhanced control and handling versus drum brakes. If you are so inclined, aftermarket drum-to-disc conversion kits can be had that will allow you to retrofit modern disc brakes on your drum-equipped ATV or UTV.
Also, when purchasing disc brake rotors, be sure you understand where and how you ride and pay attention to the different types of brake rotors there are in the market. The majority of ATV brake rotors are a solid single-piece fixed design while others are a 2-piece floating or 2-piece fixed rotor. Rotors can have flat blank faces no drilled holes which offer the greatest amount of brake biting surface. They can also be drilled or cut for the purpose of thermoregulation and to reduce unsprung weight.
Wave rotors also help sling sticky mud away from the brake pads, which helps inhibit the damage sustained during mudding. Think of touching a stick of butter onto a frying pan. When the pan is cold, the stick of butter takes a while for it to start melting onto the surface of the metal.
If you fire the stove and increase the flame, the butter has an easier time softening up and melting onto the face of the pan. Now, when the flame is at its highest setting, the butter will melt, burn, and vaporize upon contact with the hot metal.
This effect is also happening when you apply your brakes. The brake caliper and brake disc. The metal part at the bottom of the picture is a wheel spacer, which is not an original part on the bike. Hand lever operated disc brakes activate the brake calipers either on all four wheels.
Or they activate only on the two front wheels together with one of the rear wheels. The latter option is true on bikes that rely on the rear diff to have brakes on both rear wheels. Thus needing a caliper on only one of them. The pressure on all calipers is equal as there is no proportioning valve like you would find on most cars. Many bikes also feature a foot pedal in addition to the hand lever. On bikes fitted with just disc brakes on all four wheels, this pedal basically works just the same way as the hand lever.
It does have its own master cylinder that pushes brake fluid to the calipers, as described above. It might, however, have its brake fluid reservoir located somewhere else on the bike. Another key difference is that the foot pedal will not operate the front brakes on all bikes. On some, it will only operate the rear. The master cylinder on the foot pedal will not be connected to the front calipers on these bikes. The most common setup on newer bikes is one caliper on each wheel.
The hand lever will operate all calipers, while the foot pedal will operate just the rear calipers. Some older bikes have their own separate caliper trailing for the foot brake, usually fitted on one of the rear wheels.
And even on some newer bikes, you will only find one single caliper fitted on one of the rear wheels. Bikes set up this way, with a caliper just on one of the rear wheels, will likely have a locked rear diff, effectively making both wheels brake when you step on the pedal. If you suddenly need to stop at fast as possible, activating just the rear wheel brakes will on these bikes give a much longer stopping distance than when all wheels are braking.
Or, you can test the bike at slower speeds on an open gravel lot, with no risk of smashing into others. ATVs that do not have disc brakes will likely have drum brakes. Drum brakes are more common on cheaper or older models. You may also run into models with drum brakes on the rear wheels but disc brakes on the front. Drum brake systems are fairly simple designs, but they are generally not as effective as disc brakes. Operates the same way as on disc brake systems.
The cable consists of a thin steel wire inside a protective housing where it can slide freely back and forth as you operate the brake lever. Brake hub The brake hub is fitted where the suspension meets the wheel and spins freely at the same speed which the wheel turns.
The drum is all metal, and inside, it is shaped like the inside of a drum, hence the name, drum brakes. The inside steel walls of the hub serve the same purpose as the discs on the disc brakes. They create friction when brake pads are pushed against them. Two brake shoes in each hub are the most common setup.
The brake cable is connected to a lever on the brake hub, that when pulled, forces the brake shoes outward against the steel drum, creating the braking effect. Small springs connected directly to the shoes then retract them away from the drum when you release the brake lever or foot pedal. Parking brake Most bikes are fitted with a parking brake system to help keep the bike in a stationary position whenever parked.
While on many cars, you usually have a separate brake wire that bypasses the hydraulic braking system, this is not the case on ATVs. Mud is Bad While ATVs are designed to run across all terrains as its name suggests, the chassis and suspension system is specially designed to handle all terrains. Hence, after a run through muddy trials, it is good to clean your ATV to keep the braking system in the best shape.
Q: How to effectively use the brakes while going downhill? A: When you are riding downhill, it is always better to shift your weight backwards and using the back brakes. Using front brakes is not recommended going downhill as it can be dangerous and can even flip your vehicle upside down. Q: Can we use both brakes together for braking?
A: Yes, it is always better to use both brakes as while you are moving forward, it is the front brakes that does all the hard work. But when you use only the front brakes at high speed, there are more chances of you losing control of your ATV and locking up your wheels.
