Chevrolet Sailo Hatchback Brake Drum

This Rear Brake Drum of Chevrolet Sailo hatchback brake drum 9024113, features a far wider mating surface than you might expect. It is a compatible match for high-volume vehicles including Sail, Lova, Aveo, Epica and the classic old Cruze, provided the vehicles are equipped with rear drum brakes. It has an inner diameter of 200 mm, a drum depth of 45 mm, a 5-hole PCD of 105 mm for positioning, and a central bore of 57.1 mm. Do not hastily install it after a casual measurement with a vernier caliper; you must cross-reference the specifications of the original drum removed from the vehicle.

In terms of casting, this rear brake drum (part number 9024113) for all Chevrolet Sailo hatchback models is manufactured from HT200 gray cast iron with a carbon equivalent controlled at approximately 3.9%. Its metallographic structure consists of a pearlite matrix with uniformly distributed Type A graphite, and the friction surface hardness ranges from HB170 to HB210. When the brake shoes expand, the inner wall of the drum remains undeformed, friction builds up rapidly, and the handbrake can firmly hold the rear of the vehicle on slopes. The out-of-roundness of the inner bore at factory delivery is limited to less than 0.03 mm, eliminating issues such as brake pedal kickback or repetitive clattering vibrations from the rear during low-speed braking after installation.

Advantages of Surface Spraying Technology: The outer black coating of rear brake drum Part No. 9024113 for all Chevrolet Sailo hatchback models resists mud and water immersion

Unlike front brake discs shielded by wheel hubs, rear brake drums are fully exposed under the chassis, directly splattered with mud, water and gravel. We never cut corners on the surface treatment of Rear Brake Drum of Chevrolet Sailo hatchback brake drum 9024113 models. First, iron phosphating is applied to seal pores on the cast iron surface, followed by electrostatic spraying of a black epoxy polyester powder coat. After high-temperature curing, the coating thickness uniformly ranges from 30 to 40 micrometers. After a 320-hour salt spray test, barely any rust spots can be found on the outer shell of the disassembled drum.

What is the most practical merit of the paint finish on this rear brake drum Part No. 9024113 for all Chevrolet models? After driving on salt-spread roads in winter, de-icing agents are highly corrosive. Ordinary drums turn heavily rusted yellow within two to three months and even get seized and impossible to disassemble. Our coating withstands chloride corrosion and will not peel off even when blasted upward from under the vehicle with a high-pressure water gun. Moreover, the paint only covers the outer shell and edges of the drum, while the inner friction circle remains a bare precision-machined surface. Brake shoes only make contact with raw iron without touching the coating, so the paint will never flake off throughout the service life.The friction surface is precision-ground, with uniform roughness and close fit with brake shoes. Combined with surface treatment, it can achieve stable braking torque, low-noise operation and efficient heat dissipation, and effectively suppress thermal fading even under harsh braking conditions; it is directly compatible with the original factory, can be quickly installed without modification, meets the original factory standards, and ensures driving safety under various road conditions.

Advantages of the Factory Processing Workshop: Rear Brake Drum of Chevrolet Sailo hatchback brake drum 9024113, each processed on a dynamic balancing machine

Our workshop has set up a dedicated production line exclusively for rear brake drums (Part No. 9024113) fitted to all Chevrolet Sailo hatchback models. Upon arrival, raw castings first undergo hardness sorting; those with excessive hardness deviation are returned directly to the foundry. Horizontal CNC lathes paired with special expansion sleeve tooling are adopted for clamping. A single clamping operation completes full machining of the inner friction surface, bearing locating bore and end face. The inner circular surface roughness is controlled between Ra 1.6 and Ra 2.0, maximizing the contact area once brake shoes expand.

In terms of inspection, every Rear Brake Drum of Chevrolet Sailo hatchback brake drum 9024113 models must pass through an automatic dynamic balancing machine. Units with an unbalance mass exceeding 8 g·cm undergo on-machine weight removal. The weight removal slots are milled shallow and narrow to avoid compromising structural strength. A coordinate measuring machine (CMM) conducts sampling inspections on inner circular roundness, end face runout and PCD hole positional tolerance, with all inspection data uploaded in real time. Full traceability is available via QR code scanning, which retrieves the production date and shift of each brake drum.

Q: I removed the rear brake drum of my Lova and it still looks pretty thick. Do I have to replace it with thisRear Brake Drum of Chevrolet Sailo hatchback brake drum 9024113?
A: Don't just judge by its thickness. Measure it with an internal caliper; if the inner diameter exceeds 201.5 mm, it has exceeded the service limit. Replacement is required if deep grooves or steps form on the inner circle, or if the vehicle fails to stop immediately when the handbrake is pulled at high speeds. Drum brakes dissipate heat poorly. Once a worn drum heats up, its inner diameter expands, and the brake shoes cannot clamp tightly even when fully extended-by then, it will be too late to replace it.

Q: Does this Rear Brake Drum for all Chevrolet Sailo hatchback models, Part Number 9024113 require running-in after installation?
A: Just avoid harsh handbrake drifting for the first few hundred kilometers. The brake shoes will naturally fit the inner surface of the drum, and full contact will be achieved after 100 to 200 kilometers of running-in. However, be sure to sand off the aged surface layer of the brake shoes with fine sandpaper before installation; otherwise, the brake pedal will feel spongy during the first few stops, which can be unsettling.

Q: My Chevrolet Cruze is equipped with rear disc brakes. Can I use this Rear Brake Drum for all Chevrolet Sailo hatchback models, Part Number 9024113?
A: It is not compatible. Vehicles with rear disc brakes and rear drum brakes feature different chassis structures. Your Cruze has solid rear discs with separate calipers, an entirely different system from this brake drum. Send your vehicle identification number to customer service before purchasing, and we will verify the correct fit for you.

Q: Will the black outer paint coating on this Rear Brake Drum for all Chevrolet Sailo hatchback models, Part Number 9024113 pass vehicle inspection?
A: Absolutely. Original factory brake drums come with black anti-rust coating, and the paint color of our product matches the factory specification. Vehicle inspections do not check the color of brake drums-they only verify whether braking force meets standards. Once installed, your braking force will reach the required threshold and handbrake parking gradient performance will qualify, allowing you to pass the inspection on the first try.

In recent years, the global automotive braking industry has been undergoing new changes. Many people consider drum brakes as outdated technology, but in fact, with the popularization of new energy vehicles, drum brakes are embracing new application scenarios. The rear drum brake technical route represented by theRear Brake Drum of Chevrolet Sailo hatchback brake drum 9024113 is also continuously upgrading and optimizing in line with industry trends. According to the 2026 Global Drum Brake Market Report, with the widespread adoption of electric vehicle regenerative braking systems, the frequency of rear wheel braking usage has significantly decreased, and the previous wear failure has gradually shifted to corrosion failure. However, the enclosed structure of drum brakes can better isolate moisture and sediment, reduce rust on braking components, and collect brake dust, meeting the requirements of the upcoming Euro 7 particulate emission regulations. For this reason, more and more entry-level new energy models are re-adopting rear drum brake configurations, and the technological research and development of drum brakes is moving towards the direction of sealing, low maintenance, and high corrosion resistance.

When using the Rear Brake Drum of Chevrolet Sailo hatchback brake drum 9024113 in daily life, mastering a few tips can effectively extend its service life. Firstly, try to avoid frequent sudden braking. For long downhill sections, it is recommended to use engine braking to assist in deceleration, reducing the continuous high-temperature load on the brake drum. Do not wash the car immediately after continuous braking, as sudden cooling of the high-temperature brake drum is prone to deformation, which may lead to brake judder problems later. Secondly, perform regular inspections of the braking system every 20,000 kilometers, clean the friction dust inside the brake drum, check the wear of the brake shoes, and observe if there are abnormal grooves or rust spots on the inner surface of the brake drum. Addressing minor issues early can avoid greater losses. Thirdly, after driving in rainy weather or wading through water, lightly step on the brakes several times to use the heat generated by braking to dry the moisture inside the drum, preventing rust on internal components and ensuring normal braking performance for the next use. The Rear Brake Drum of Chevrolet Sailo hatchback brake drum 9024113 already undergoes high-standard external anti-rust treatment, but paying attention to these details in daily use can further extend its service cycle..
