What component holds the brake shoes to the backing plate?
Springs hold the brake shoes in place so they don’t contact the drum when the brakes aren’t active. When the driver pushes down on the brake pedal, this places pressure on the hydraulic fluid in the brake lines. At the top of the backing plate is a wheel cylinder containing two pistons, one at either end.
How do ATV rear brakes work?
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.
Where are the brackets on a front brake pad?
Each front brake pad has corresponding to it three metal ancillary parts, the brackets/clips I referred to. These three parts are diagrammed and labeled in the service manual as: “Inner shim” is a thin metal backing plate that is the same shape as the pad and goes directly on the back of the pad.
Can you use the original brake pad backing?
The plastic adhesive backing that may be included in the box with the new pads is just a supplemental noise reduction shim. Use it of course, but understand it does not stand in place of the original shim parts. The original shim parts can fit right on over the supplemental one.
What kind of hardware are brake pads made of?
Just one question: The original pads had various ancillary metal hardware attached to them: slotted metal backing shims, some other metal brackets with tabs that wrapped around the sides at certain places, and a small L-shaped clip/bracket (not sure what to call it) that fit at the bottom corner hole where the pin goes through.
Where does the inner Shim go on a brake pad?
“Inner shim” is a thin metal backing plate that is the same shape as the pad and goes directly on the back of the pad. Several rounded slots are cut out of the middle of its face. A few small tabs extend from it and right angle around the long sides of the pad, I presume to hug the pad and keep it in place.
Do you need disc brakes on an ATV?
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.
How does the foot brake work on an ATV?
The hand lever will operate all calipers, while the foot pedal will operate just the rear calipers. But there are some variations out there. Some older bikes have their own separate caliper (trailing) for the foot brake, usually fitted on one of the rear wheels.
Where are the brake calipers on an ATV?
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.
How is a brake disc connected to a wheel?
Each wheel has a brake disc that is directly connected to- and spins at the same speed as the wheel. When the brake fluid reaches the piston inside the caliper, the piston is being pushed against the brake pad, which in turn, is being pushed against the brake disc.
