An excellent braking system is critical to your vehicle. This article highlights some of the essential factors that bring out the differences between the brake shoes and brake pads.

Introduction:
Brake shoes are curved pieces of metal that carry brake lining that is inside the drum systems.
They work in drum systems, and when a driver applies the brake, the shoe is forced outwards by a wheel cylinder creating friction between the drum and the lining hence bring the axle into a stop. The brake shoes is applied mostly on the rear axle.
On the other hand, brake pads are found on disc brake systems. They are a flat steel piece attached to calipers on the wheel system.
When you press a brake pedal, the calipers hold the brake pads against a disk called rotor hence creating the friction that stops the vehicle.
Things to Consider about Brake Shoes vs. Brake Pads

Construction difference
The two types of braking systems have been constructed differently. Brake shoes are applicable with a drum system where a drum aligns with the wheel.
The brake shoes have a spring or cylinder that enable its outward motion to press against the drum to create the friction that stops the vehicle.
Brake shoes are attached to a metallic component that holds it in place. The braking system relies on a hydraulic cylinder found on the drum.
Brake pads, on the other hand, are attached to the caliper that presses it in place to stop the rotor. The reasoning behind it is, it tries to clamp the disk hence stopping it.

Brake force difference or efficiency
The brake force that is applied by the brake pads is quite high. The brake pads do a lot of work in bringing the vehicle to a halt.
The friction force created by the brake pads is quite high, and that leads to wearing out of the brake pads. It leads to the replacement of the brake pads now and then.
Brake shoes do not apply much braking force as the brake pads. Many at times the contact is moderate or low but is quite enough to bring the car into a stop.
Brake shoes are widely used in heavy vehicles and also in the rear axle of many cars. On the other hand, brake pads are commonly used in smaller vehicles.

Cost
The cost of purchasing brake shoes is lower than that of brake pads. The cost of manufacturing brake shoes is cheaper also, and that is why still many vehicles have brake shoes.
Therefore it is common to see a full replacement cost of brake shoes being half the cost of replacing brake pads.
Since the brake shoes apply mostly in the rear axle, it takes quite a long time to replace them.
They also have a lesser work input compared to the brake pads hence the reason why brake pads wear quite quickly. With less replacement comes lower cost.

Friction and wear
Brake pads generally work more in braking the vehicle hence wear quickly compared to brake shoes. Brake shoes used in rear axle offer the best traction and more friction on the drum thus higher efficiency.
Brake pads are always in immense strain and thus wear out quickly. The brake shoe is more applicable in parking that immediate braking in smaller cars.

Final Verdict
In general brake shoes are advantageous in many ways but are not best for front wheels. The two when combined create best results, and that is why many vehicles take that form of the braking system.
The brake shoe is meant to handle a higher friction force; hence, it is good to spot whenever it has started wearing out so that you ensure safety. Both systems are great and different and separately work when applied right.
