Why does Toyota still use drum brakes?

Why Toyota Still Uses Drum Brakes
Toyota still uses drum brakes in some of its vehicles for several reasons:
1. Rear Brake Strength:
– Rear brakes do not need to be as strong as front brakes and must be weaker. Drum brakes are considered good enough for the rear as they are more amenable to use as a parking/emergency brake.
2. Cost-Effectiveness:
– Drum brakes are cheaper to manufacture than disc brakes, allowing Toyota to keep manufacturing costs low and pass the savings onto consumers .
3. Off-Roading Benefits:
– Drum brakes are better for off-roading, ensuring that the brakes won’t be affected by dirt, which can be beneficial for vehicles like the Toyota Tacoma.
4. Braking Performance:
– For vehicles like the Tacoma, there may not be a measurable improvement in braking distances or brake feel by upgrading to disc brakes.
5. Rear Brake Usage:
– On most unloaded pickups, the front brakes do 70%-80% of the braking, while the rear brakes are barely doing anything. Therefore, drivers may not notice a difference in braking feel between drum and disc brakes on these vehicles.
In summary, Toyota’s decision to continue using drum brakes in certain vehicles is based on considerations of rear brake strength, cost-effectiveness, off-roading benefits, and the specific braking dynamics of their vehicles.

Why do new cars still come with rear drum brakes?

Auto manufacturers continue to use rear drum brakes for two main reasons – lower cost and less complexity. Drum brakes are less expensive to produce because they require fewer parts than disc brakes. Unlike disc brakes, drum brakes can function as both a service brake and a parking brake.

Which is better disc or drum brakes in cars?

Braking power is better in a disc brake. They are capable of effectively stopping a vehicle even at high speeds. Disc brakes have a lower chance of failure from overheating because of their open-air design. Disc brakes stay cleaner, and their components do not rust easily.

Why do modern cars use drum brakes?

This makes the cars more efficient. In addition to the other comments about drum brakes lasting long and disc brakes don’t get used much (since these are RWD motors that does regen on rear wheels), it also decreases rolling resistance as the pads drag a bit when coasting.

What are the disadvantages of drum brakes?

Drum brake disadvantages
Under hard braking, the diameter of the drum increases slightly due to thermal expansion, the driver must press the brake pedal farther. Brake shoes can overheat to the point where they become glazed. Excessive brake drum heating can cause the brake fluid to vapourise.

When did Toyota stop using drum brakes?

It’s only fitting that with a high-tech hybrid powertrain comes … four-wheel disc brakes. It looks like the 2024 Toyota Tacoma will be leaps and bounds ahead of the current-gen pickup.

Will 2024 Tacoma have drum brakes?

Though not directly related to suspension, the 2024 Tacoma has a new brake system, and all versions of the new Tacoma have rear disk brakes.

What is the main problem with drum brakes?

Uneven wear on brake drums can occur due to misaligned brake shoes, uneven brake shoe contact, or irregular braking habits. This problem can result in inconsistent braking performance, vibrations, or brake noise.

Do drum brakes last longer than disc?

Brake drums are a durable part of the braking system and typically can last several thousand kilometres. They also generally last a bit longer than disc brakes due to the way they are built. They wear slower and are hardier, making them a great choice for passenger vehicles.

Why do Toyotas have drum brakes?

However, there are a few good reasons why Tacomas have drums: Cost: Drum brakes are cheaper to manufacture than disc brakes, and Toyota passes the savings along to its customers. On the Tacoma (and most unloaded pickups), the front brakes do 70%-80% of the braking. The rear brakes are barely doing anything.

Will 2024 Tacoma have disc brakes?

2024 Toyota Tacoma: Now With Disc Brakes, More Power, Impressive Payload, and So Much More. For 2024, the Toyota Tacoma is all-new. That means a new frame, new powertrains, and seriously beefed-up suspension upgrades. There is also a new Trailhunter trim with overland parts from ARB.
